4+6\div 2-5^2+4+6

解答

4 + 6 \div 2 - 5^{2} + 4 + 6

- 8

求解步骤

4 + 6 \div 2 - 5^{2} + 4 + 6

遵循 PEMDAS 运算顺序

计算幂值

5^{2} : 25

5^{2}

5^{2} = 25

= 25

= 4 + 6 \div 2 - 25 + 4 + 6

乘除（左右）

6 \div 2 : 3

6 \div 2

6 \div 2 = 3

= 3

= 4 + 3 - 25 + 4 + 6

加减（左右）

4 + 3 - 25 + 4 + 6 : - 8

4 + 3 - 25 + 4 + 6

4 + 3 = 7

= 7 - 25 + 4 + 6

7 - 25 = - 18

= - 18 + 4 + 6

- 18 + 4 = - 14

= - 14 + 6

- 14 + 6 = - 8

= - 8

= - 8

(7 \times 12) + 10 \div 2 - 11

1 - 5 (\frac{4}{19})

5 - [6 - 2 (1 - 8) - 3 + 6] + 5

\frac{1}{2} 7 (11 + 15)

17 - 6 \times 3
