I'll solve the math problems shown in the worksheet step by step.
Let me work through each problem carefully:
Problem 1 (Set B4 - Word Problem):
An African elephant and an Asian elephant weigh 18,785 pounds together. If the African elephant weighs 11,423 pounds, how much does the Asian elephant weigh?
To find the Asian elephant's weight:
- Total weight = 18,785 pounds
- African elephant = 11,423 pounds
- Asian elephant = Total - African elephant
- Asian elephant = 18,785 - 11,423
Let me calculate:
```
18,785
- 11,423
--------
7,362
```
The Asian elephant weighs
7,362 pounds.
Problem 2 (Set B4 - Word Problem):
Last year, Mr. Smith saved $95,625 and his wife saved $76,___ (the number is cut off). Let me check what I can see... It appears to say "$76," but the rest is cut off. I cannot complete this problem without the full amount.
Set B3 Problems:
Problem 1:
```
41,232
+ 28,453
--------
```
Adding column by column from right to left:
- Ones: 2 + 3 = 5
- Tens: 3 + 5 = 8
- Hundreds: 2 + 4 = 6
- Thousands: 1 + 8 = 9
- Ten thousands: 4 + 2 = 6
Answer:
69,685
Problem 2:
```
56,827
- 24,703
--------
```
Subtracting column by column from right to left:
- Ones: 7 - 3 = 4
- Tens: 2 - 0 = 2
- Hundreds: 8 - 7 = 1
- Thousands: 6 - 4 = 2
- Ten thousands: 5 - 2 = 3
Answer:
32,124
Problem 6:
```
320,568
- 14,375
---------
```
Subtracting column by column from right to left:
- Ones: 8 - 5 = 3
- Tens: 6 - 7 → need to borrow. 16 - 7 = 9
- Hundreds: 4 - 3 = 1 (after borrowing)
- Thousands: 0 - 4 → need to borrow. 10 - 4 = 6
- Ten thousands: 1 - 1 = 0 (after borrowing)
- Hundred thousands: 3 - 0 = 3
Answer:
306,193
Problem with partial numbers (appears to be problem 2 on right side):
I can see "3,146" and "9,382" but the operation isn't clear. This appears incomplete.
Problem 11:
Add 140,723 to 358,246
```
140,723
+ 358,246
---------
```
Adding column by column:
- Ones: 3 + 6 = 9
- Tens: 2 + 4 = 6
- Hundreds: 7 + 2 = 9
- Thousands: 0 + 8 = 8
- Ten thousands: 4 + 5 = 9
- Hundred thousands: 1 + 3 = 4
Answer:
498,969
Problem 12:
Subtract 35,240 from 741,523
```
741,523
- 35,240
---------
```
Subtracting column by column:
- Ones: 3 - 0 = 3
- Tens: 2 - 4 → need to borrow. 12 - 4 = 8
- Hundreds: 4 - 2 = 2 (after borrowing)
- Thousands: 1 - 5 → need to borrow. 11 - 5 = 6
- Ten thousands: 3 - 3 = 0 (after borrowing)
- Hundred thousands: 7 - 0 = 7
Answer:
706,283

Final Answer:
Set B4:
1. Asian elephant weighs:
7,362 pounds
2. [Incomplete - missing wife's savings amount]
Set B3:
1. 41,232 + 28,453 =
69,685
2. 56,827 - 24,703 =
32,124
6. 320,568 - 14,375 =
306,193
11. 140,723 + 358,246 =
498,969
12. 741,523 - 35,240 =
706,283
