Final Answer:
Problem 5 is the trick problem.
──────────────────────────────────────
Explanation:
Let’s look at each problem one by one to see which one is NOT multiplication.
1) 6 pens in 1 pack → 7 packs → 6 × 7 = 42 pens.
✔ Multiplication.
2) 1 car has 4 wheels → 12 cars → 4 × 12 = 48 wheels.
✔ Multiplication.
3) 1 paperclip needs 10 cm wire → 11 paperclips → 10 × 11 = 110 cm.
✔ Multiplication.
4) Sally runs 3 miles per day → 2 weeks = 14 days → 3 × 14 = 42 miles.
✔ Multiplication.
5) Buys 12 apples on Monday + 7 more on Tuesday → 12 + 7 = 19 apples.
✘ This is ADDITION, not multiplication! That’s the trick!
6) 1 multipack has 6 packets → 12 multipacks → 6 × 12 = 72 packets.
✔ Multiplication.
7) Rocket takes 7 seconds per mile → 14 miles → 7 × 14 = 98 seconds.
✔ Multiplication.
So only problem 5 uses addition. That’s why it’s the “trick” problem!
