MATHS FACTS : Addition or Subtraction of Numbers – Part 1

Remember

1. 0 added to a number gives same number

0 + 0 = 06 + 0 = 60 + 5 = 58 + 0 = 80 + 9 = 9
0 added to a number gives same number

2. 1 added to a number gives next number

1 + 2 = 36 + 1 = 71 + 4 = 57 + 1 = 81 + 9 = 10
1 added to a number gives next number

3. 0 subtracted from a number gives same number

2 – 0 = 27 – 0 = 71 – 0 = 18 – 0 = 89 – 0 = 9
0 subtracted from a number gives same number

4. 1 subtracted from a number gives previous number

2 – 1 = 18 – 1 = 72 – 1 = 19 – 1 = 86 – 1 = 5
1 subtracted from a number gives previous number

5. Number subtracted from itself gives zero (0)

1 – 1 = 08 – 8 = 02 – 2 = 09 – 9 = 06 – 6 = 0
Number subtracted from itself gives zero (0)
