16 - 13
16 - 13 =
3
2.
18 - 17
18 - 17 =
1
3.
21 - 15
21 - 15 =

44 - 31
44 - 31 =
13

Row 3
9.
88 - 43
88 - 43 =
45
10.
90 - 13
90 - 13 =
77
11.
25 - 32
Since 25 < 32, this is negative:
25 - 32 =
-7
12.
36 - 53
36 < 53 → 36 - 53 =
-17

📝 Notes:
- Most problems are straightforward two-digit subtractions.
- Problems like
25 - 32 and
36 - 53 result in
negative numbers, which may be intended to introduce the concept of negative results or might be a mistake depending on the grade level.
- If only positive answers are expected, those two problems could be skipped or revised — but mathematically, they are correct as written.
Let me know if you'd like a printable version or explanation for regrouping (borrowing) in any of these!
