6× 5+(15\div 5)-2+6

解答

6 \times 5 + (15 \div 5) - 2 + 6

37

求解步骤

6 \times 5 + (15 \div 5) - 2 + 6

遵循 PEMDAS 运算顺序

计算括号内的值

(15 \div 5) : 3

15 \div 5

15 \div 5 = 3

= 3

= 6 \times 5 + 3 - 2 + 6

乘除（左右）

6 \times 5 : 30

6 \times 5

6 \times 5 = 30

= 30

= 30 + 3 - 2 + 6

加减（左右）

30 + 3 - 2 + 6 : 37

30 + 3 - 2 + 6

30 + 3 = 33

= 33 - 2 + 6

33 - 2 = 31

= 31 + 6

31 + 6 = 37

= 37

= 37

5 \times 2^{6}

2500 - 1200 - 700 - 350

4 + (- 7) + 9 + (- 1) + 6 + (- 8) + 3 + (- 20)

\frac{1}{( - 1 ) ^{2} + 1}

(4/3) + (5/3) + (8/3)
