Although less used than the mathematical operators listed above, Excel uses the caret character
( ^ ) as the exponent operator in formulas.

Exponents are sometimes referred to as repeated multiplication since the exponent - or power as it is sometimes called - indicates how many times the base number should be multiplied by itself.

For example, the exponent  4^2 (four squared) - has a base number of 4 and an exponent of 2, or is said to be raised to the power of two.

Either way, the formula is a short form of saying that the base number should be multiplied together twice (4 x 4) to give a result of 16.

Similarly, 5^3 (five cubed) indicates that the number 5 should be multiplied together a total of three times (5 x 5 x 5) to give an answer of 125.

In addition to the basic math formulas listed above, Excel has several functions - built-in formulas - that can be used to carry out a number of mathematical operations.

These functions include:

The SUM function - makes it easy to add up columns or rows of numbers;

The PRODUCT function - multiplies two or more numbers together. When multiplying just two numbers, a multiplication formula is easier;

The QUOTIENT function - returns only return the integer portion (whole number only) of a division operation;

The MOD function - returns only the remainder of a division operation.
