Solve +650:[+3*(+176-388+144):(+196-358+145)-142]=

$$+ 650 : [ + 3 \cdot ( + 176 - 388 + 144 ) : ( + 196 - 358 + 145 ) - 142 ] =$$

Evaluate

$$-5$$

Solution Steps

Subtract 388 from 176 to get -212.

$$\frac{650}{\frac{3\left(-212+144\right)}{196-358+145}-142}$$

Add -212 and 144 to get -68.

$$\frac{650}{\frac{3\left(-68\right)}{196-358+145}-142}$$

Multiply 3 and -68 to get -204.

$$\frac{650}{\frac{-204}{196-358+145}-142}$$

Subtract 358 from 196 to get -162.

$$\frac{650}{\frac{-204}{-162+145}-142}$$

Add -162 and 145 to get -17.

$$\frac{650}{\frac{-204}{-17}-142}$$

Divide -204 by -17 to get 12.

$$\frac{650}{12-142}$$

Subtract 142 from 12 to get -130.

$$\frac{650}{-130}$$

Divide 650 by -130 to get -5.

$$-5$$
