!! If you are familiar with the elementary concepts of addition, e.g. because you have taken the quiz before, YOU MAY SKIP THE THEORY PART and head down to take the math quiz and test your knowledge !!

**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**

While “a+b” is called the **sum** of “a” and “b”, there are a variety of designations used for “a” and “b”:

- The most accurate appelations for “a” would be first addend, and for “b” second addend.
- Sometimes “a” is also called augment.
- “a” or “b” can also be called
**addend(s)**or**summand(s)**or simply**term(s)**.

In the following a quiz with a variety of questions that test your knowledge and skill level in elementary arithmetics.

Do not use a digital calculator, but try to solve the questions in your head. You can also use paper and pencil or the note/memo app on your smartphone to carry out manual arithmetics (carry and borrow operations).
