Here are the solutions for the double-digit subtraction problems with regrouping. I have solved each one step-by-step to ensure accuracy.
Row 1:
1.
43 - 27: You cannot subtract 7 from 3, so you borrow from the 4 (making it 3) and add 10 to the 3 (making it 13). $13 - 7 = 6$ and $3 - 2 = 1$. The answer is
16.
2.
55 - 29: Borrow from the 5 (making it 4) to make the ones place 15. $15 - 9 = 6$ and $4 - 2 = 2$. The answer is
26.
3.
82 - 76: Borrow from the 8 (making it 7) to make the ones place 12. $12 - 6 = 6$ and $7 - 7 = 0$. The answer is
6.
4.
67 - 19: Borrow from the 6 (making it 5) to make the ones place 17. $17 - 9 = 8$ and $5 - 1 = 4$. The answer is
48.
Row 2:
5.
81 - 12: Borrow from the 8 (making it 7) to make the ones place 11. $11 - 2 = 9$ and $7 - 1 = 6$. The answer is
69.
6.
74 - 38: Borrow from the 7 (making it 6) to make the ones place 14. $14 - 8 = 6$ and $6 - 3 = 3$. The answer is
36.
7.
90 - 37: Borrow from the 9 (making it 8) to make the ones place 10. $10 - 7 = 3$ and $8 - 3 = 5$. The answer is
53.
8.
65 - 49: Borrow from the 6 (making it 5) to make the ones place 15. $15 - 9 = 6$ and $5 - 4 = 1$. The answer is
16.
Row 3:
9.
71 - 49: Borrow from the 7 (making it 6) to make the ones place 11. $11 - 9 = 2$ and $6 - 4 = 2$. The answer is
22.
10.
66 - 59: Borrow from the 6 (making it 5) to make the ones place 16. $16 - 9 = 7$ and $5 - 5 = 0$. The answer is
7.
11.
78 - 49: Borrow from the 7 (making it 6) to make the ones place 18. $18 - 9 = 9$ and $6 - 4 = 2$. The answer is
29.
12.
91 - 47: Borrow from the 9 (making it 8) to make the ones place 11. $11 - 7 = 4$ and $8 - 4 = 4$. The answer is
44.
Final Answer:
16, 26, 6, 48
69, 36, 53, 16
22, 7, 29, 44
