subtraction
Removing one number
Subtraction is the mathematical operation of taking one quantity away from another—the inverse of addition.
The result is called the difference: Seven minus three equals four.
Beyond arithmetic, subtraction refers to any removal or reduction: The subtraction of key players weakened the team.
