Problem Overview:
The task involves solving addition and subtraction problems with 3-digit numbers, focusing on those that result in sums or differences where the tens place is a
3. After solving each problem, you trace the bear's path to its cave by connecting the trees whose answers have a
3 in the tens place.
Step-by-Step Solution:
#### 1. Solve Each Problem:
We will solve all the given addition and subtraction problems and identify which results have a
3 in the tens place.

#### Top Row:
1.
687 + 143
\[
687 + 143 = 830
\]
- Tens place:
3 (Keep this tree).
2.
584 - 146
\[
584 - 146 = 438
\]
- Tens place:
3 (Keep this tree).
3.
727 + 204
\[
727 + 204 = 931
\]
- Tens place:
3 (Keep this tree).
4.
364 - 125
\[
364 - 125 = 239
\]
- Tens place:
3 (Keep this tree).
---
#### Middle Row:
5.
148 + 132
\[
148 + 132 = 280
\]
- Tens place:
8 (Discard this tree).
6.
952 - 219
\[
952 - 219 = 733
\]
- Tens place:
3 (Keep this tree).
7.
497 + 236
\[
497 + 236 = 733
\]
- Tens place:
3 (Keep this tree).
8.
470 + 289
\[
470 + 289 = 759
\]
- Tens place:
5 (Discard this tree).
---
#### Bottom Row:
9.
486 + 250
\[
486 + 250 = 736
\]
- Tens place:
3 (Keep this tree).
10.
845 - 486
\[
845 - 486 = 359
\]
- Tens place:
5 (Discard this tree).
11.
657 - 594
\[
657 - 594 = 63
\]
- Tens place:
3 (Keep this tree).
12.
604 - 266
\[
604 - 266 = 338
\]
- Tens place:
3 (Keep this tree).
---
#### Trees to Keep:
The trees whose answers have a
3 in the tens place are:
- Top row: 1, 2, 3, 4
- Middle row: 6, 7
- Bottom row: 9, 11, 12
---
#### 2. Trace the Bear's Path:
Now, connect the trees in a logical path from the bear to the cave, ensuring you only use the trees identified above. The path should follow the sequence of these trees.
---
Final Answer:
The bear's path includes the following trees (in order):
1.
687 + 143 (830)
2.
584 - 146 (438)
3.
727 + 204 (931)
4.
364 - 125 (239)
5.
952 - 219 (733)
6.
497 + 236 (733)
7.
486 + 250 (736)
8.
657 - 594 (63)
9.
604 - 266 (338)
Boxed Final Answer:
\[
\boxed{687 + 143, 584 - 146, 727 + 204, 364 - 125, 952 - 219, 497 + 236, 486 + 250, 657 - 594, 604 - 266}
\]
