Solve 17*2-{5+[16-3*(7-3*1)]:2-4}

$$17 \cdot 2 - \{ 5 + [ 16 - 3 \cdot ( 7 - 3 \cdot 1 ) ] : 2 - 4 \}$$

Evaluate

$$31$$

Solution Steps

Multiply 17 and 2 to get 34.

$$34-\left(5+\frac{16-3\left(7-3\times 1\right)}{2}-4\right)$$

Multiply 3 and 1 to get 3.

$$34-\left(5+\frac{16-3\left(7-3\right)}{2}-4\right)$$

Subtract 3 from 7 to get 4.

$$34-\left(5+\frac{16-3\times 4}{2}-4\right)$$

Multiply 3 and 4 to get 12.

$$34-\left(5+\frac{16-12}{2}-4\right)$$

Subtract 12 from 16 to get 4.

$$34-\left(5+\frac{4}{2}-4\right)$$

Divide 4 by 2 to get 2.

$$34-\left(5+2-4\right)$$

Add 5 and 2 to get 7.

$$34-\left(7-4\right)$$

Subtract 4 from 7 to get 3.

$$34-3$$

Subtract 3 from 34 to get 31.

$$31$$

Factor

$$31$$
