Problem Description:
The task involves solving a series of addition problems where three-digit numbers are added to two-digit numbers. Some of these problems require regrouping (carrying over digits). The goal is to calculate each sum accurately.
Solution:
####
Step 1: Solve the first row
1.
832 + 95
- Add the units place: \( 2 + 5 = 7 \)
- Add the tens place: \( 3 + 9 = 12 \) (write down 2, carry over 1)
- Add the hundreds place: \( 8 + 0 = 8 \), plus the carried-over 1 gives \( 8 + 1 = 9 \)
- Result:
927
2.
644 + 33
- Add the units place: \( 4 + 3 = 7 \)
- Add the tens place: \( 4 + 3 = 7 \)
- Add the hundreds place: \( 6 + 0 = 6 \)
- Result:
677
3.
201 + 92
- Add the units place: \( 1 + 2 = 3 \)
- Add the tens place: \( 0 + 9 = 9 \)
- Add the hundreds place: \( 2 + 0 = 2 \)
- Result:
293
####
Step 2: Solve the second row
1.
778 + 97
- Add the units place: \( 8 + 7 = 15 \) (write down 5, carry over 1)
- Add the tens place: \( 7 + 9 = 16 \), plus the carried-over 1 gives \( 16 + 1 = 17 \) (write down 7, carry over 1)
- Add the hundreds place: \( 7 + 0 = 7 \), plus the carried-over 1 gives \( 7 + 1 = 8 \)
- Result:
875
2.
696 + 12
- Add the units place: \( 6 + 2 = 8 \)
- Add the tens place: \( 9 + 1 = 10 \) (write down 0, carry over 1)
- Add the hundreds place: \( 6 + 0 = 6 \), plus the carried-over 1 gives \( 6 + 1 = 7 \)
- Result:
708
3.
936 + 38
- Add the units place: \( 6 + 8 = 14 \) (write down 4, carry over 1)
- Add the tens place: \( 3 + 3 = 6 \), plus the carried-over 1 gives \( 6 + 1 = 7 \)
- Add the hundreds place: \( 9 + 0 = 9 \)
- Result:
974
####
Step 3: Solve the third row
1.
502 + 47
- Add the units place: \( 2 + 7 = 9 \)
- Add the tens place: \( 0 + 4 = 4 \)
- Add the hundreds place: \( 5 + 0 = 5 \)
- Result:
549
2.
566 + 36
- Add the units place: \( 6 + 6 = 12 \) (write down 2, carry over 1)
- Add the tens place: \( 6 + 3 = 9 \), plus the carried-over 1 gives \( 9 + 1 = 10 \) (write down 0, carry over 1)
- Add the hundreds place: \( 5 + 0 = 5 \), plus the carried-over 1 gives \( 5 + 1 = 6 \)
- Result:
602
3.
377 + 84
- Add the units place: \( 7 + 4 = 11 \) (write down 1, carry over 1)
- Add the tens place: \( 7 + 8 = 15 \), plus the carried-over 1 gives \( 15 + 1 = 16 \) (write down 6, carry over 1)
- Add the hundreds place: \( 3 + 0 = 3 \), plus the carried-over 1 gives \( 3 + 1 = 4 \)
- Result:
461
