Addition and Subtraction of Positive and Negative Numbers:
6 - 5 = 1 or -5 + 6 = 1
5 - 6 = -1 or -6 + 5 = -1
-6 - 5 = -11
6 + 5 = 11

Examples:

  1. 25 - 4 + 9
    • First add the two numbers, 25 and 9 which gives 34.
    • Subtract 4 from 34, 34-4 = 30
    Answer: 30

  2. 45 - 56 - 67
    • Subtract 45-56, since 56 is greater, we subtract 45 from 56 and put the sign of the negative number. This gives -11
    • Now the problem reduces to -11 - 67 which gives -78.(When there are two negative numbers, find their sum and use the negative sign)
    Answer: -78
