To add 64 and 37 mentally, you can break it down into simpler steps.
1. Recognize that 37 is 3 less than 40.
2. So, you can adjust 64 by separating it into 3 + 61. That means you can consider it as:
- \( 64 - 3 + 37 + 3 = 61 + 40 \).
3. Now, you can add:
- \( 61 + 40 = 101 \).
Thus, the correct sum of 64 and 37 is **101**.
