18\div 3× 5\div 3\div 2× 5× 2

解答

18 \div 3 \times 5 \div 3 \div 2 \times 5 \times 2

50

求解步骤

18 \div 3 \times 5 \div 3 \div 2 \times 5 \times 2

遵循 PEMDAS 运算顺序

乘除（左右）

18 \div 3 = 6

= 6 \times 5 \div 3 \div 2 \times 5 \times 2

6 \times 5 = 30

= 30 \div 3 \div 2 \times 5 \times 2

30 \div 3 = 10

= 10 \div 2 \times 5 \times 2

10 \div 2 = 5

= 5 \times 5 \times 2

5 \times 5 = 25

= 25 \times 2

25 \times 2 = 50

= 50

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

2^{3} + 5 - 8 \div 2 + 3^{2}

- 2 (3) + 3

(3 \times + 2) (3 \times (- 2))

1 1^{2} + 1 2^{2}
