Answer 5

Let's break it down:

You started with the equation **37 + 3 + 61**.

- First, add **37 + 3** which equals **40**.
- Then add this to **61**:
- **40 + 61 = 101**.

Among the options you provided:

- **40 + 60** = 100 (not correct)
- **40 + 62** = 102 (not correct)
- **40 + 61** = 101 (this is correct)

So, **37 + 3 + 61 can be added to become 40 + 61**.

Therefore, the answer is **40 + 61**.
