Arithmetic actions and operations in Excel

What arithmetic operations are available in Excel? All of them. Arithmetic is a subset of broader math operations. In classic arithmetic there are five basic actions:

  1. Addition
  2. Subtraction
  3. Multiplication
  4. Division
  5. Exponentiation (raising to a power)

A special case of exponentiation is extracting a root. For example, a square root is the same as raising to the power of 1/2 (0.5).

Objects of arithmetic operations

Arithmetic actions operate on numbers, so numeric cell values are the primary target. However, booleans also participate in arithmetic: TRUE behaves like 1, and FALSE like 0. This is handy in conditional calculations.

Dates and times work too: in Excel they are just numbers with a date/time format, so you can add, subtract, multiply, etc.

Arithmetic functions

Excel has functions that perform these actions (see the Excel functions glossary):

  • SUM — adds numbers.
  • PRODUCT — multiplies numbers.
  • POWER — raises a number to a power.
  • QUOTIENT — integer division (drops the remainder).

There are no dedicated functions for subtraction or standard division because their equivalents are straightforward:

  • Subtraction is addition with a negative addend (e.g., A1 + (-B1)).
  • Division is multiplication by a fraction (e.g., divide by 2 ⇢ multiply by 0.5).

If you don’t care about the remainder, use QUOTIENT for integer division.

Arithmetic operators in Excel (table)

Here are the operators and simple formula examples:

OperationOperatorExample
Addition+=A1+5
Subtraction=A2-10
Multiplication*=A3*15
Division/=A4/20
Exponentiation^=A5^2

Do arithmetic without formulas (paste special)

You can apply arithmetic to many cells without writing formulas using Paste Special → Operation. Copy a cell with the constant (e.g., 10), select your range, and use Paste Special to add, subtract, multiply, or divide in place.

Use Paste Special for arithmetic on ranges

The limitation: your constant must exist on the sheet and be copied to the clipboard first.

Faster arithmetic with !SEMTools

!SEMTools streamlines these actions. Instead of placing a helper cell and copying it, you type the constant directly in a small dialog and apply the action to the selection. It also includes exponentiation (missing from Paste Special) and nearby menus for other math operations, such as rounding or multiplying by a random number within a chosen range.
