Subtract 4 takes away a double of 2, so children who know subtract 2 can do it in two steps.
The pattern in the answers
The starting numbers 5 to 16 give the answers 1 to 12, and 8 - 4 = 4 is the one fact whose answer equals the number taken away.
Tip for the subtract 4 facts
Subtract 2 two times. For 13 - 4, 13 - 2 = 11 and 11 - 2 = 9.
The 3 hardest facts
- 11 − 4 = 7 (matching addition: 4 + 7 = 11)
- 12 − 4 = 8 (matching addition: 4 + 8 = 12)
- 13 − 4 = 9 (matching addition: 4 + 9 = 13)
Each starts in the teens. Count back to ten first, then take away the rest: 12 - 2 = 10, then 2 more makes 8.
Check with addition
Every subtraction fact is an addition fact turned around. Add the answer back to 4 to get the number you started with.
- 1 + 4 = 5, so 5 − 4 = 1
- 2 + 4 = 6, so 6 − 4 = 2
- 3 + 4 = 7, so 7 − 4 = 3
- 4 + 4 = 8, so 8 − 4 = 4
- 5 + 4 = 9, so 9 − 4 = 5
- 6 + 4 = 10, so 10 − 4 = 6
- 7 + 4 = 11, so 11 − 4 = 7
- 8 + 4 = 12, so 12 − 4 = 8
- 9 + 4 = 13, so 13 − 4 = 9
- 10 + 4 = 14, so 14 − 4 = 10
- 11 + 4 = 15, so 15 − 4 = 11
- 12 + 4 = 16, so 16 − 4 = 12

Questions parents ask
Does subtract 4 need a new idea?
No. It uses subtract 2 twice, or the double 4 + 4 = 8 to find 8 - 4 = 4. Reuse the tools learned earlier.
What is a good warm-up for subtract 4?
Start with 5 - 4 up to 8 - 4, where the answers are 1 to 4, then add the larger starting numbers.
