Math in Maple Learn exists *within* groups. When you start Maple Learn, the first group is already there:

To enter math, ensure that your cursor is in a group. Then, you can use a mixture of typing, the math toolbar at the top of the screen, and keyboard shortcuts to enter your expression, as you prefer.

You can switch between different palettes on the toolbar using the buttons on the left of the toolbar.

You can use the free Maple Calculator app to enter math into Maple Learn. While logged in to your Maplesoft account, use the camera to take a picture of your math.

Next, in Maple Learn, click on the Cloud icon on the toolbar. A list of your most recent expressions from the Maple Calculator will appear. Select the expression you want, and it will automatically get added to your Maple Learn document.

Note: You must be signed into the app and Maple Learn with the same login credentials in order to enter a problem using your phone's camera.

To keep your work organized and readable, put unrelated problems, side calculations, or substeps of a larger problem into separate groups. When you start Maple Learn, Group 1 is already there. You can insert a new group anywhere on the canvas by doing one of the following:

- Double-click on the canvas
- Type
**[ Ctrl ]**+**[ G ]** - Click the New Group icon

Groups are made up of a collection of cells, where each line of math or piece of text is in its own cell.

To add a new line (cell) at the bottom of a group, simply put your cursor on the last line and press **[ Enter ]**.

To insert a new cell below the line your cursor is on, click on the Insert Cell icon or press **[ Shift ]+[ Enter ]**. When using **[ Shift ]+[ Enter ]**, your cursor can be in any position in that line except the very first position at the beginning of the line.

To insert a new cell *above* the line your cursor is on, press **[ Home ]+[ Shift ]+[ Enter ]**, or place your cursor at the beginning of the line, to the left of the first character, and press **[ Shift ]+[ Enter ]**.

You can include text inside a group, or place text anywhere on your canvas as a free floating text box.

You can **add text to a group** in several different ways:

- Click on the Pencil icon to add a text cell beneath the currently selected cell
- From the
**Insert**menu, select**Text** - In an empty math cell, press [ spacebar ] or to convert the cell from a math cell to a text cell.

To add **text anywhere on the canvas**, click an area on the canvas outside of any groups, and

- Click on the Pencil icon ; or
- Type
**[ Ctrl ]+ [ I ]**(that’s an “i”)

You can **add a new line to your text cell or text box** by pressing **[ Shift ]+[ Enter ] **or **[ Alt ]+[ Enter ]**

The light bulb provides easy access to a **Quick Actions** menu. When you click on the light bulb, you will be offered a choice of common actions to perform, such as parameterizing your expression, or removing the expression from the plot window.

If you want to give a value to a variable, you assign that value to the variable using the assignment operator, ‘:=’. For example:

*n* := 5

*t* := *s*+2**r*

**f**(x) := sin(x)+cos(x)

These variables will then automatically have those values in subsequent statements. In the first example, if you then type “5*n*+1”, Maple Learn will automatically give a result of 26, because *n* now has the value of 5.

A slider will appear whenever you assign a numeric value to a variable, so that you can easily explore the effects of different values for that variable. If you don’t want it there, you can remove it using the **Quick Actions** menu.

**Note:** It is useful to understand the difference between equations and assignment statements. As explained above, assignments change the value of the variable, and are performed using the assignment operator, ‘:=’. By contrast, the ’=’ symbol is used in equations, for example, x + z = 2y, or y = 2x + 5. The = sign specifies a mathematical relationship between the expressions on the left- and right- hand sides, but does not affect the values of any of the variables. You can continue to *x¸y*, and *z* as unknowns in other calculations.

When appropriate, you can **convert an equation to an assignment** by clicking on the light bulb to bring up the **Quick Actions** menu and selecting **Convert to Assignment**.

Defining a function is similar to assigning a value to a variable, and uses the assignment operator ‘:=’, like this:

**f**(x) := x^{3} + 3x^{2}

Once the function is assigned, you can call it use the same notation you would see in a textbook.

Notice that the function name, **f**, appears in bold. In Maple Learn, all function names are in bold so you can distinguish between a function call, such as **f**(t+1), and multiplication involving parentheses, such as w(t+1) = w*t + w.

You can move a group by dragging the grey vertical bar, or handle, that appears to the right of the group number.

Note that when you move a group, the group numbers may change. The group numbers reflect the order of execution of the calculations. Calculations are done in "reading order" based on group position. When you move a group to a different part of the page, it can affect the order that the calculations are performed. See How are assignments evaluated in Maple Learn? for more information.

Yes. Shortcuts are available for math entry, document navigation, group creation, and more. Here is the list of keyboard shortcuts for Maple Learn.

Getting Results

Premium math operations are more advanced computations that go beyond what standard numeric calculators can do, such as factoring polynomials, inverting matrices, or solving equations. The free version of Maple Learn provides unlimited plotting and calculator use, and also allows you to use up to ten Premium math operations every day, A Premium account gives you unlimited access to all premium math operations.

The menu buttons for premium operations have a lock symbol on them, which is unlocked when the menu is available and locked if you reach your limit for the day.

To upgrade to Premium, or learn more about the benefits of a Premium account, visit www.maplesoft.com/getlearn.

The free version of Maple Learn allows you to use up to ten Premium math operations every day, as well as unlimited plotting and calculator use. Once you have reached that limit, the lock icon on the premium menu options will show that the menu is locked, and you will need to wait until the following day to perform your operation, or upgrade to a Premium account for unlimited access.

To upgrade to Premium, or learn more about the benefits of a Premium account, visit www.maplesoft.com/getlearn.

The free version of Maple Learn allows you to use up to ten Premium math operations every day. To see how many operations you have remaining, hover your mouse pointer over one of the lock symbols found on the premium menu items. The open lock shows that the menu operation is still available, and the popup will show you how many you have used so far and how many remain.

Maple Learn performs simple computations, such as those a calculator can do, automatically. If you want to perform a more complex operation, such as factorization, equation solving, or calculating a limit, you can request it by selecting the operation from the Context Panel. This way, you can choose whether or not you want to go straight to the answer or work out some or all of the steps by yourself.

If the built-in Maple Learn calculator doesn’t return a result automatically, you can request it by selecting the operation you want in the Context Panel.

If the operation you want is not listed, please use the Flag a Problem button to let us know!

If you use a Context Panel operation to calculate a result, and then go back and change the original problem, your result turns orange to indicate that it is now out of date. A refresh icon will appear in the lower left corner of your out-of-date result. Click on that icon to update the result.

Groups are ordered from left to right and top to bottom (same as reading text on a page), based on the position of the top left corner of the group. Each group is given a number to indicate the order that assignments to variables are performed.

By Groups

Group numbers indicate the order the groups will be evaluated. All assignments in Group 1 happen before all assignments in Group 2, etc.

Here are some examples:

If *a* used in Group 1 as an unknown variable, and then *a* is assigned the value of 10 in Group 2, the a in Group 1 will remain as an unknown. The a used in Group 2 and Group 3 will have a value of 10.

If *b* :=3 appears in Group 1, and *b* := 5 in Group 2, *b* will also have a value of 5 in Group 3 and later.

Within a Group

When you assign an expression or value to a variable, calculations that come after the assignment will use the assigned value. In general, calculations that occur before the assignment are not affected.

However, within a single group, when a slider is present, the numeric value assigned by the slider is known throughout the entire group, rather than just for calculations that come after the slider. This enables the following example to produce a graph of a line that changes based on the slider value for b.

Plotting

Graphs are generated in the plot window as soon as you begin to type your expression or function. The graph for each expression or function within a group appears the plot window, so you can add additional plots simply by adding those expressions to the same group.

All expressions in a group are plotted automatically, but you can turn off any you do not wish to see. Click on the light bulb beside the expression that should not be plotted to bring up the **Quick Actions** menu and select **Exclude from Plot**.

The color icon located to the left of each expression or function in a group corresponds to the color of the curve on the plot window.

You can use your mouse wheel or trackpad to zoom into or out of a plot. If you only want to zoom along one axis while keeping the other fixed, you can first click on the “Only zoom horizontally” or “Only zoom vertically” icons to the right of the plot window.

Saving and Sharing

To save a Maple Learn document, you must be signed in to your Maplesoft account. If you don’t have an account, you can create one for free.

Once you are signed in, you can save your document by giving it a name. At the top left of the screen, replace “Untitled document” with your chosen file name. After that, any changes you make will be saved automatically.

The free version of Maple Learn allows you to have up to five Maple Learn documents saved at any given time. Once you have reached five documents, you will be unable to save any more until you have deleted one of your saved documents, or updated to a Premium account for unlimited saving.

To delete a saved document, go to **File > Open MapleCloud** to bring up MapleCloud. Navigate to your My Files folder or Maple Learn folder, and use the Delete icon in the Actions column to delete the Maple Learn document you wish to remove.

To upgrade to Premium, or learn more about the benefits of a Premium account, visit www.maplesoft.com/getlearn.

The free version of Maple Learn allows you to open up to five shared Maple Learn documents a day. Once you have reached that limit, you will need to wait until the following day to open the shared document, or upgrade to a Premium account for unlimited access to shared documents.

While you are working, Maple Learn regularly autosaves your current document. If you have not saved your document explicitly by giving it a name, those autosaves are stored as temporary documents. Temporary documents are available as an emergency back-up, in case of disruption during a session. If you need to access a temporary document, you must first save it explicitly by renaming the file using the Save icon under Actions. By naming the file, you will change the documents status from “temporary” to “saved”, and then you can interact with it like any other saved document.

To access your temporary documents click on the **Temporary Documents **radio button in your Maple Learn folder within the MapleCloud.

By default, Maple Learn automatically saves changes to your document whenever you make a change. You can turn autosave off and on for a particular document. From the **Settings** menu, select **Disable Autosave. **

Once disabled, autosave will remain off for this document until you turn it on again. An indicator will appear next to the document name if autosave has been disabled. Other documents are not affected.

To save a document after you have disabled autosave, turn autosave back on again. From the **Settings** menu, select **Enable Autosave.**
