Step-by-step solution for: Multiplying 2 Digits by 2 Digit #1 - KidsPressMagazine.com
It looks like you've uploaded an image with a set of multiplication problems, and there are cartoon superhero characters at the bottom. The task appears to be solving the multiplication problems listed.
Let me solve each multiplication problem step by step:
---
1. $ 87 \times 44 $
$$
87 \times 44 = (80 + 7) \times 44 = 80 \times 44 + 7 \times 44 = 3520 + 308 = 3828
$$
2. $ 17 \times 62 $
$$
17 \times 62 = (10 + 7) \times 62 = 10 \times 62 + 7 \times 62 = 620 + 434 = 1054
$$
3. $ 26 \times 41 $
$$
26 \times 41 = (20 + 6) \times 41 = 20 \times 41 + 6 \times 41 = 820 + 246 = 1066
$$
4. $ 45 \times 51 $
$$
45 \times 51 = (40 + 5) \times 51 = 40 \times 51 + 5 \times 51 = 2040 + 255 = 2295
$$
---
5. $ 21 \times 18 $
$$
21 \times 18 = (20 + 1) \times 18 = 20 \times 18 + 1 \times 18 = 360 + 18 = 378
$$
6. $ 34 \times 25 $
$$
34 \times 25 = 34 \times (100/4) = (34 \times 100)/4 = 3400/4 = 850
$$
Or: $ 30 \times 25 = 750 $, $ 4 \times 25 = 100 $, total = $ 850 $
7. $ 37 \times 62 $
$$
37 \times 62 = (30 + 7) \times 62 = 30 \times 62 + 7 \times 62 = 1860 + 434 = 2294
$$
8. $ 88 \times 53 $
$$
88 \times 53 = (80 + 8) \times 53 = 80 \times 53 + 8 \times 53 = 4240 + 424 = 4664
$$
---
9. $ 35 \times 21 $
$$
35 \times 21 = 35 \times (20 + 1) = 35 \times 20 + 35 \times 1 = 700 + 35 = 735
$$
10. $ 61 \times 40 $
$$
61 \times 40 = 61 \times 4 \times 10 = 244 \times 10 = 2440
$$
11. $ 84 \times 71 $
$$
84 \times 71 = (80 + 4) \times 71 = 80 \times 71 + 4 \times 71 = 5680 + 284 = 5964
$$
12. $ 79 \times 20 $
$$
79 \times 20 = 79 \times 2 \times 10 = 158 \times 10 = 1580
$$
---
13. $ 47 \times 52 $
$$
47 \times 52 = (40 + 7) \times 52 = 40 \times 52 + 7 \times 52 = 2080 + 364 = 2444
$$
14. $ 99 \times 72 $
$$
99 \times 72 = (100 - 1) \times 72 = 100 \times 72 - 1 \times 72 = 7200 - 72 = 7128
$$
15. $ 35 \times 40 $
$$
35 \times 40 = 35 \times 4 \times 10 = 140 \times 10 = 1400
$$
16. $ 46 \times 77 $
$$
46 \times 77 = (40 + 6) \times 77 = 40 \times 77 + 6 \times 77 = 3080 + 462 = 3542
$$
---
17. $ 28 \times 34 $
$$
28 \times 34 = (20 + 8) \times 34 = 20 \times 34 + 8 \times 34 = 680 + 272 = 952
$$
18. $ 50 \times 33 $
$$
50 \times 33 = 5 \times 10 \times 33 = 5 \times 330 = 1650
$$
19. $ 83 \times 68 $
$$
83 \times 68 = (80 + 3) \times 68 = 80 \times 68 + 3 \times 68 = 5440 + 204 = 5644
$$
20. $ 12 \times 49 $
$$
12 \times 49 = 12 \times (50 - 1) = 12 \times 50 - 12 \times 1 = 600 - 12 = 588
$$
