Subtraction Table for 15
Each row subtracts numbers 1 through 12 from 15. Subtraction is the inverse of addition and appears in change-making, scores, and measurements.
Every difference here stays whole and non-negative — the smallest is 15 − 12 = 3. Subtract an even number and parity survives; subtract an odd and it flips: 15 − 3 = 12. Taking away 10 moves only the tens digit: 15 − 10 = 5, and nothing else in the number moves. Read the difference column bottom-up and it climbs, one step at a time, back to 14 — a countdown fully reversed.

Frequently asked questions
What is 15 − 4?
15 − 4 = 11.
What does the difference column mean?
The difference is the result after subtracting — here, the second number in each row, such as 15 − 2 = 13.
Is subtraction commutative?
No — swapping the order changes the result: 15 − 3 = 12, but 3 − 15 = -12. That is why reading the row direction matters.
