98-87+(35-6)-(84\div 6)+9

解答

98 - 87 + (35 - 6) - (84 \div 6) + 9

35

求解步骤

98 - 87 + (35 - 6) - (84 \div 6) + 9

遵循 PEMDAS 运算顺序

计算括号内的值

(35 - 6) : 29

35 - 6

35 - 6 = 29

= 29

= 98 - 87 + 29 - (84 \div 6) + 9

计算括号内的值

(84 \div 6) : 14

84 \div 6

84 \div 6 = 14

= 14

= 98 - 87 + 29 - 14 + 9

加减（左右）

98 - 87 + 29 - 14 + 9 : 35

98 - 87 + 29 - 14 + 9

98 - 87 = 11

= 11 + 29 - 14 + 9

11 + 29 = 40

= 40 - 14 + 9

40 - 14 = 26

= 26 + 9

26 + 9 = 35

= 35

= 35

5^{2} \times 4^{3}

4 - 2 \cdot (5 - 8) + 2 \cdot [5 \cdot (2 - 7 + 3) - 7]

(1)^{2} - 4 (1) + 4

(1)^{2} - 4 (1) + 3

7 - (- 19) - 18 + (- 19) + 18
