(12\div 4)× (3+5)

解答

(12 \div 4) \times (3 + 5)

24

求解步骤

(12 \div 4) \times (3 + 5)

遵循 PEMDAS 运算顺序

计算括号内的值

(12 \div 4) : 3

12 \div 4

12 \div 4 = 3

= 3

= 3 \times (3 + 5)

计算括号内的值

(3 + 5) : 8

3 + 5

3 + 5 = 8

= 8

= 3 \times 8

乘除（左右）

3 \times 8 : 24

3 \times 8

3 \times 8 = 24

= 24

= 24

30 - (2 \times 6 + 15/3) + 8 \times 3/6

- 5 (3)^{2} + 5 (3) + 5

\frac{- 2 - 4}{- 2 ^{2} - 5 ( - 2 ) - 36}

2^{10} + 2^{0} + 2

4 (4)^{2} + 10
