Answer 3

I can help you with math problems. To perform the addition, you need to add 1 to the first addend and subtract 1 from the second addend. This way, the first addend becomes 10 and the second addend becomes 3. Then you can add 10 and 3 easily. The equation becomes:

$$9+4=9+(1+3)=(9+1)+(4-1)=10+3=13$$

The answer is 13.
