Question

Identify the correct subtraction equation for the given number line.

• A. 22 - 8 - 14
• B. 21 - 7 = 14
• C. 21 - 8 - 13
• D. 22 - 7 = 13

Answer 1

The correct option is A 22 - 8 - 14

Say:
Let’s observe the number line and identify the correct equation based on it.

Steps:

• From 22, 2 jumps are taken backward to reach 20. 22 - 2 = 20
• From 20, 6 more jumps are taken backward to reach 14. 20 - 6 = 14
• In all, 8 jumps are taken backward from 22 to 14. 22 - 8 = 14
• Hence, option B is the answer.
