How to add, subtract, divide and multiply

Excel can perform a number of basic mathematical functions, and the articles below will show you how to create the formulas needed to add, subtract, multiply, or divide numbers. Also, learn how to work with exponents and basic math functions.

Exponents in Excel

Although less used than the mathematical operators listed above, Excel uses the caret ( ^ ) as an exponent operator in formulas. Exponents are sometimes called repeated multiplication because the exponent tells how many times to multiply the base number by itself.

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

Anyway, the formula is shorthand, stating that the base number must be multiplied by two (4 x 4) to get a result of 16.

Similarly, 5^3 (five dice) indicates that the total number 5 must be multiplied by three (5 x 5 x 5), giving 125.

Excel math functions

In addition to the basic mathematical formulas listed above, Excel has several functions – built-in formulas – that can be used to perform many mathematical operations.

These features include:

  • That SUMMER Function – Add columns or rows of numbers.
  • That PRODUCT Function – Multiplies two or more numbers together. When multiplying just two numbers, a multiplication formula is simpler.
  • That QUOTIENT Function – Returns only the integer part (integer only) of a division operation.
  • That MOD Function – Returns only the remainder of a division operation.
