12\div 12× (10× 2)

解答

12 \div 12 \times (10 \times 2)

20

求解步骤

12 \div 12 \times (10 \times 2)

遵循 PEMDAS 运算顺序

计算括号内的值

(10 \times 2) : 20

10 \times 2

10 \times 2 = 20

= 20

= 12 \div 12 \times 20

乘除（左右）

12 \div 12 \times 20 : 20

12 \div 12 \times 20

12 \div 12 = 1

= 1 \times 20

1 \times 20 = 20

= 20

= 20

3 (10)^{2} - 11

(2 + 5)^{3}

2^{2} \times 3^{2} \div 3^{2} \times 2^{2}

4 \times 5 \div (- 2) - 10 + 19

9 (2)^{2} - 2 (2)
