Subtraction Table for 7
Each row subtracts numbers 1 through 12 from 7. Subtraction is the inverse of addition and appears in change-making, scores, and measurements.
Rows drop below zero once the subtrahend passes 7: 7 − 8 = −1, and the column keeps walking down — the smallest value here is 7 − 12 = -5. Subtract an even number and parity survives; subtract an odd and it flips: 7 − 3 = 4. Taking away 10 moves only the tens digit: 7 − 10 = -3, a first dip below zero. Read the difference column bottom-up and it climbs, one step at a time, back to 6 — a countdown fully reversed.

Frequently asked questions
What is 7 − 4?
7 − 4 = 3.
What does the difference column mean?
The difference is the result after subtracting — here, the second number in each row, such as 7 − 2 = 5.
Is subtraction commutative?
No — swapping the order changes the result: 7 − 3 = 4, but 3 − 7 = -4. That is why reading the row direction matters.
