Returns the sum of two numbers.
value1 + value2
Press the [+] key to paste +.
This command works on all calculators.
The + operator adds two numbers, variables, or expressions together. Order of operations dictates that it's calculated after * and /, and at the same time as -.
The + operator can also be used on lists and matrices. For the most part, it behaves in the intuitive way, distributing the operation over each element. However, adding a number to a matrix (in either order) behaves differently: the number is only added along the main diagonal of the matrix. For "normal" addition that applies to every element of the matrix, see .+.
