PEMDAS rule
2^2 = 2²
1:54 - 2^5 + 19 - 9
= 54 - 32 + 19 - 9
= 22 + 19 - 9
= 41 - 9
= 32
2:(72-10) × 6 + 8
= 62 × 6 + 8
= 372 + 8
= 380
3:34 + 8 - 6 ÷ 3
= 34 + 8 - 2
= 42 - 2
= 40
4:42 ÷ 7 × (15 - 6) + 15
= 42 ÷ 7 × 9 + 15
= 6 × 9 + 15
= 54 + 15
= 69 (W teacher)
5:5^2 - 7 + 8 × 10
= 25 - 7 + 8 × 10
= 25 - 7 + 80
= 18 + 80
= 98 (dream grade ko)
