Questions tagged [subtraction]

Subtraction is a mathematical operation that represents the removal of an object from a collection.

Subtraction is a mathematical operation that represents the removal of an object from a collection. The minus sign (-) signifies subtraction.

Subtraction is anticommutative, meaning that changing the order changes the sign of the answer. It is not associative, meaning that when one subtracts more than two numbers, order in which subtraction is performed matters.

3 - 2 = 1

3-2 number line
