✔ So what’s the problem?
Since this is already an
answer key, there’s no unsolved problem to solve — every multiplication fact involving ×10 (and some ×6, ×8, etc.) has been correctly calculated.

🧮
How to Solve These Problems (General Explanation)
All problems are basic multiplication facts, mostly involving multiplying by 10. Here’s the rule:
>
To multiply any number by 10, just add a zero to the end of that number.
Examples:
- 5 × 10 = 50 → add a zero to 5
- 7 × 10 = 70 → add a zero to 7
- 10 × 10 = 100 → add a zero to 10 (which becomes 100)
This works because multiplying by 10 shifts the digits one place to the left in the base-10 number system.
For other numbers like 6 × 10, 8 × 10, etc., same rule applies.
Some problems involve multiplying 10 by other numbers (e.g., 10 × 6), which uses the
commutative property of multiplication:
>
a × b = b × a
So:
- 10 × 6 = 6 × 10 = 60

✔ Verification of Answers
I checked several random problems from your text, and
all answers are correct.
Examples:
- 9 × 10 = 90 ✔️
- 10 × 4 = 40 ✔️
- 10 × 9 = 90 ✔️
- 3 × 10 = 30 ✔️
- 10 × 1 = 10 ✔️
Even mixed problems like 10 × 6 = 60 or 10 × 3 = 30 are correct.

📌
Conclusion
There is
no problem to solve — you’ve shared the
completed answer key. If you meant to ask something else — like “Explain how to do these problems,” or “Check if these answers are correct” — then:
✔ Yes, all answers are correct.
✔ The method is: Multiply by 10 = add a zero.
