Solve (57+6):9-[9+(8*4-16)-(36:4-5)]:7=

$$( 57 + 6 ) : 9 - [ 9 + ( 8 \cdot 4 - 16 ) - ( 36 : 4 - 5 ) ] : 7 =$$

Evaluate

$$4$$

Solution Steps

Add 57 and 6 to get 63.

$$\frac{63}{9}-\frac{9+8\times 4-16-\left(\frac{36}{4}-5\right)}{7}$$

Divide 63 by 9 to get 7.

$$7-\frac{9+8\times 4-16-\left(\frac{36}{4}-5\right)}{7}$$

Multiply 8 and 4 to get 32.

$$7-\frac{9+32-16-\left(\frac{36}{4}-5\right)}{7}$$

Add 9 and 32 to get 41.

$$7-\frac{41-16-\left(\frac{36}{4}-5\right)}{7}$$

Subtract 16 from 41 to get 25.

$$7-\frac{25-\left(\frac{36}{4}-5\right)}{7}$$

Divide 36 by 4 to get 9.

$$7-\frac{25-\left(9-5\right)}{7}$$

Subtract 5 from 9 to get 4.

$$7-\frac{25-4}{7}$$

Subtract 4 from 25 to get 21.

$$7-\frac{21}{7}$$

Divide 21 by 7 to get 3.

$$7-3$$

Subtract 3 from 7 to get 4.

$$4$$

Factor

$$2^{2}$$
