Subtraction Table for 9
Each row subtracts numbers 1 through 12 from 9. Subtraction is the inverse of addition and appears in change-making, scores, and measurements.
Rows drop below zero once the subtrahend passes 9: 9 − 10 = −1, and the column keeps walking down — the smallest value here is 9 − 12 = -3. Subtract an even number and parity survives; subtract an odd and it flips: 9 − 3 = 6. Taking away 10 moves only the tens digit: 9 − 10 = -1, a first dip below zero. Read the difference column bottom-up and it climbs, one step at a time, back to 8 — a countdown fully reversed.

Frequently asked questions
What is 9 − 4?
9 − 4 = 5.
What does the difference column mean?
The difference is the result after subtracting — here, the second number in each row, such as 9 − 2 = 7.
Is subtraction commutative?
No — swapping the order changes the result: 9 − 3 = 6, but 3 − 9 = -6. That is why reading the row direction matters.
