Elementary Arithmetics - Addition (quiz and brief tutorial)
A typical example of manual arithmetic is this pencil-and-paper addition. The five numbers are the summands (or addends or terms), and the result below the horizontal line is the sum. The handwritten digits on the top are the carries.

Addition is the (most) basic operation of arithmetic. It is very simple and straightforward, as you don’t have to worry in which order you add theterms, thus a+b = b+a, and a + (b+c) = (a+b) + c.

This is a result of the associative law of addition.

NOMENCLATURE
