1. (11 + 2) x 10 + 8 =2?
1. (11 + 2) x 10 + 8 = 2. 10 + 12 x (2 + 3) = 3. (10 + 2) x (7 + 3) = 4. (10÷2 + 5) x 3 = 5. (5 - 3 + 8) x 4 - 20 = 6. 22 - 8÷2x4 - 6 = 7. ( - 1 / 2x1 / 4)2 = 8. (3. 5 - 7 + 2. 5) (2 - 4)3 = 9. (5x3x12) ÷ ( - 7 + 4 - 9 + 3) = 10. (2 + 7 - 6)2 ÷ ( - 2x3)3 = 11. ( - 5 + 4 - 3) ( - 4) ÷ ( - 8 + 5 - 7) =.
