Let’s solve each multiplication problem one by one. We’ll go row by row, left to right (a then b), and write the answer after the equals sign.
---
1 a. 10 × 7 =
Think: 10 groups of 7 → 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 70
✔ 70
1 b. 5 × 7 =
Think: 5 groups of 7 → 7 + 7 + 7 + 7 + 7 = 35
✔ 35
---
2 a. 7 × 5 =
Same as 5 × 7 → 35
✔ 35
2 b. 9 × 7 =
Think: 9 groups of 7 → 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 63
Or: 10×7=70, minus 7 → 63
✔ 63
---
3 a. 7 × 9 =
Same as 9 × 7 → 63
✔ 63
3 b. 7 × 8 =
Think: 7 groups of 8 → 8+8+8+8+8+8+8 = 56
Or: 7×10=70, minus 7×2=14 → 70-14=56
✔ 56
---
4 a. 7 × 6 =
Think: 6 groups of 7 → 7+7+7+7+7+7 = 42
✔ 42
4 b. 7 × 2 =
Just 7 + 7 = 14
✔ 14
---
5 a. 7 × 12 =
Think: 7×10=70, 7×2=14 → 70+14=84
✔ 84
5 b. 12 × 7 =
Same as above → 84
✔ 84
---
6 a. 7 × 4 =
7+7+7+7 = 28
✔ 28
6 b. 2 × 7 =
Same as 7×2 → 14
✔ 14
---
7 a. 11 × 7 =
Think: 10×7=70, plus 1×7=7 → 70+7=77
✔ 77
7 b. 7 × 7 =
7 groups of 7 → 49 (you can memorize this!)
✔ 49
---
8 a. 7 × 11 =
Same as 11×7 → 77
✔ 77
8 b. 8 × 7 =
Same as 7×8 → 56
✔ 56
---
9 a. 7 × 3 =
7+7+7 = 21
✔ 21
9 b. 3 × 7 =
Same → 21
✔ 21
---
10 a. 1 × 7 =
One group of 7 → just 7
✔ 7
10 b. 4 × 7 =
Same as 7×4 → 28
✔ 28
---
Final Answer:
1 a. 70
1 b. 35
2 a. 35
2 b. 63
3 a. 63
3 b. 56
4 a. 42
4 b. 14
5 a. 84
5 b. 84
6 a. 28
6 b. 14
7 a. 77
7 b. 49
8 a. 77
8 b. 56
9 a. 21
9 b. 21
10 a. 7
10 b. 28
