The numbers that are grouped within a parenthesis or bracket become one unit. Test. It states that any quantity is equal to itself. The result of a subtraction is called a difference.Subtraction is signified by the minus sign, −.For example, in the adjacent picture, there are 5 − 2 apples—meaning 5 apples with 2 taken away, resulting in a total of 3 apples.
