MultiSet + operator
M + N
M + N + P + ...
M, N, P, ...
MultiSet; MultiSets, sets, or lists
M + N returns the MultiSet which is the sum of M and N, accounting for multiplicities. For example, if a has multiplicity 2 in M and 3 in N then it will have multiplicity 5 in M + N.
The M + N + P ... command performs the n-ary sum of the arguments
At least one argument must be a MultiSet for this routine to be invoked. Any other argument which is expected to be a MultiSet can be a MultiSet, a set or a list; in the latter two cases the argument is converted to a MultiSet before proceeding to evaluate this command. IsGeneralized(M) must return the same value for all MultiSet arguments M, and all non-MultiSet arguments will be promoted to MultiSets with this same property.
Increment the multiplicity of every element by 1:
The MultiSet/+ operator was introduced in Maple 2016.
