plus

Type

operator

Summary

Adds two numbers.

Syntax

<number1> + <number2>

Description

Use the + (plus) operator to add two numbers, or to add two arrays containing numbers.

To add a number to the contents of a container, use the add command instead.

If either number1 or number2 is an array, each of the array elements must be a number. If a number is added to an array, the number is added to each element. If an array is added to an array, both arrays must have the same number of elements and the same dimension, and each element in one array is added to the corresponding element of the other array.

If an element of one array is empty, the + operator treats its contents as zero.

If a math operation on finite inputs produces a non-finite output, an execution error is thrown. See math operations for more information.
