4+5(7-3)\div 2

解答

4 + 5 (7 - 3) \div 2

14

求解步骤

4 + 5 (7 - 3) \div 2

遵循 PEMDAS 运算顺序

计算括号内的值

(7 - 3) : 4

7 - 3

7 - 3 = 4

= 4

= 4 + 5 \cdot 4 \div 2

乘除（左右）

5 \cdot 4 \div 2 : 10

5 \cdot 4 \div 2

5 \cdot 4 = 20

= 20 \div 2

20 \div 2 = 10

= 10

= 4 + 10

加减（左右）

4 + 10 : 14

4 + 10

4 + 10 = 14

= 14

= 14

\frac{- 3}{1} (\frac{- 11}{3} + \frac{1}{1})

\frac{139}{6} (3)^{3}

(42 + 41) \times (11 + 8 + 25)

20000 + 1000 - 120 - 10 + 120 + 20 + 40

- 5 (2) + (- 5) (\frac{1}{16})
