Answer:
Its 13
Step-by-step explanation:
Pretty much its 9 + 4 (13) x 1 which equals 13.
13
To solve this you have to add 9 and 4 first so you get 13. Next, you have to subtract 8 from 7 so you get 1. Now all you have to do is multiply 13 and 1 so you get 13 as your answer.
9 + 4 = 13
8 - 7 = 1
13 × 1 = 13
