Parameters:
number1:
The operands number1 and number2 are literal numbers, or expressions
that evaluate to numbers, or arrays containing numbers.

number2:


Description:
Use the <+> (plus) <operator> to add two numbers, or to add two
<array|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>
<element(glossary)|elements> must be a number. If a number is added to
an <array>, the number is added to each <element(keyword)>. If an
<array> is added to an <array>, both <array|arrays> must have the same
number of <element(glossary)|elements> and the same dimension, and each
<element(keyword)> in one <array> is added to the corresponding
<element(keyword)> of the other <array>.

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

Changes:
The option to add arrays was introduced in version 1.1. In previous
versions, only single numbers could be used with the + operator.
