B. Put a (✔️) if the expression is correct and (x) if not. Write your answer before each number. 1. ( 4 + 3 ) x ( 10 + 2) - (5 x 6 ) = 65
2. 3+ (2 + 12 x 2) - 16 + 4 + 31 = 55
3. 4 ( 15 :3 ) + (6 x 3)- 4 = 34
4. ( 15 – 13 ) x 2 + 25 – (3+ 15 ) + 3 = 0
5. ( 10 - 7) + ( 2 x 14 - 4) - 10 = 0
6. 3+ ( 4 x 5) x 9 = 183
7. 35 + ( 36 – 25 + 27) - 30 + 13 = 30
8. 39 + ( 27 + 4 + 31 - ( 18 - 12) = 34
9. 24 + 29 - ( 24 - 17 + 4) + 10 = 52
10. 44 - ( 54 - 20 + 5 + 5) x 2 = 14​
