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.
