Solve 5*[3+2*(2+5-3)]-10*2:4

$$5 \cdot [ 3 + 2 \cdot ( 2 + 5 - 3 ) ] - 10 \cdot 2 : 4$$

Evaluate

$$50$$

Solution Steps

Add 2 and 5 to get 7.

$$5\left(3+2\left(7-3\right)\right)-\frac{10\times 2}{4}$$

Subtract 3 from 7 to get 4.

$$5\left(3+2\times 4\right)-\frac{10\times 2}{4}$$

Multiply 2 and 4 to get 8.

$$5\left(3+8\right)-\frac{10\times 2}{4}$$

Add 3 and 8 to get 11.

$$5\times 11-\frac{10\times 2}{4}$$

Multiply 5 and 11 to get 55.

$$55-\frac{10\times 2}{4}$$

Multiply 10 and 2 to get 20.

$$55-\frac{20}{4}$$

Divide 20 by 4 to get 5.

$$55-5$$

Subtract 5 from 55 to get 50.

$$50$$

Factor

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