(6× 4)+(15\div 5)

解答

(6 \times 4) + (15 \div 5)

27

求解步骤

(6 \times 4) + (15 \div 5)

遵循 PEMDAS 运算顺序

计算括号内的值

(6 \times 4) : 24

6 \times 4

6 \times 4 = 24

= 24

= 24 + (15 \div 5)

计算括号内的值

(15 \div 5) : 3

15 \div 5

15 \div 5 = 3

= 3

= 24 + 3

加减（左右）

24 + 3 : 27

24 + 3

24 + 3 = 27

= 27

= 27

[- 5 + 6] - [- 4 - 2] - [12 + 9 - 24] + 1

2 + 4 \times 3

- 6 (+ 2) - 2

3 (4)^{2} - 16

89 + 9 \times 9 - 21 \div 7 + 13 + 4 \times 8 - 7
