8+2^2+200/8*4+8

解答

8 + 2^{2} + 200/8 \cdot 4 + 8

120

求解步骤

8 + 2^{2} + 200/8 \cdot 4 + 8

遵循 PEMDAS 运算顺序

计算幂值

2^{2} : 4

2^{2}

2^{2} = 4

= 4

= 8 + 4 + 200/8 \cdot 4 + 8

乘除（左右）

200/8 \cdot 4 : 100

200/8 \cdot 4

200/8 = 25

= 25 \cdot 4

25 \cdot 4 = 100

= 100

= 8 + 4 + 100 + 8

加减（左右）

8 + 4 + 100 + 8 : 120

8 + 4 + 100 + 8

8 + 4 = 12

= 12 + 100 + 8

12 + 100 = 112

= 112 + 8

112 + 8 = 120

= 120

= 120

1 6^{2} + 6 3^{2}

16 - 12 \div 2^{2} + 8 \div (- 3 + 7)

53 + 22 + (35 - 20) + 45 \times 2^{2}

(54 - 8) \div (- 12)

(3^{2} + 2)^{2}
