Solve 0.2*9-9^2+4*9+8

$$0.2 \times 9- { 9 }^{ 2 } +4 \cdot 9+8$$

Evaluate

$$-35.2$$

Solution Steps

Multiply 0.2 and 9 to get 1.8.

$$1.8-9^{2}+4\times 9+8$$

Calculate 9 to the power of 2 and get 81.

$$1.8-81+4\times 9+8$$

Subtract 81 from 1.8 to get -79.2.

$$-79.2+4\times 9+8$$

Multiply 4 and 9 to get 36.

$$-79.2+36+8$$

Add -79.2 and 36 to get -43.2.

$$-43.2+8$$

Add -43.2 and 8 to get -35.2.

$$-35.2$$
