Let's solve each subtraction problem using the number line method as shown in the image.
We are asked to
subtract by moving left on the number line. The idea is:
- Start at the
first number (the minuend).
- Move
left by the number of steps equal to the
second number (the subtrahend).
- The number you land on is the
answer.

1. 8 − 1 = ?
- Start at
8
- Move
1 step left → land on
7
✔ Answer: 7
