Solve 30[2(20+2*5)-6(30-60div2)]

$$30 [ 2 ( 20 + 2 \times 5 ) - 6 ( 30 - 60 \div 2 ) ]$$

Evaluate

$$1800$$

Solution Steps

Multiply 2 and 5 to get 10.

$$30\left(2\left(20+10\right)-6\left(30-\frac{60}{2}\right)\right)$$

Add 20 and 10 to get 30.

$$30\left(2\times 30-6\left(30-\frac{60}{2}\right)\right)$$

Multiply 2 and 30 to get 60.

$$30\left(60-6\left(30-\frac{60}{2}\right)\right)$$

Divide 60 by 2 to get 30.

$$30\left(60-6\left(30-30\right)\right)$$

Subtract 30 from 30 to get 0.

$$30\left(60-6\times 0\right)$$

Multiply 6 and 0 to get 0.

$$30\left(60-0\right)$$

Subtract 0 from 60 to get 60.

$$30\times 60$$

Multiply 30 and 60 to get 1800.

$$1800$$

Factor

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