SUBTRACTION

Subtraction

Subtraction is a mathematical operation that represents the operation of removing objects from a collection. It is signified by the minus sign . For example, in the picture on the right, there are 5 - 2 apples—meaning 5 apples with 2 taken away, which is a total of 3 apples. Therefore, 5 - 2 = 3. Besides counting fruits, subtraction can also represent combining other physical and abstract quantities using different kinds of objects: negative numbers, fractions, irrational numbers, vectors, decimals, functions, matrices and more.
