Solve 84*0.1+3*(-4*0.25+3^2)+4.1+2

$$84 \cdot 0.1 + 3 \cdot ( - 4 \cdot 0.25 + 3 ^ { 2 } ) + 4.1 + 2$$

Evaluate

$$38.5$$

Solution Steps

Multiply 84 and 0.1 to get 8.4.

$$8.4+3\left(-4\times 0.25+3^{2}\right)+4.1+2$$

Multiply -4 and 0.25 to get -1.

$$8.4+3\left(-1+3^{2}\right)+4.1+2$$

Calculate 3 to the power of 2 and get 9.

$$8.4+3\left(-1+9\right)+4.1+2$$

Add -1 and 9 to get 8.

$$8.4+3\times 8+4.1+2$$

Multiply 3 and 8 to get 24.

$$8.4+24+4.1+2$$

Add 8.4 and 24 to get 32.4.

$$32.4+4.1+2$$

Add 32.4 and 4.1 to get 36.5.

$$36.5+2$$

Add 36.5 and 2 to get 38.5.

$$38.5$$

Factor

$$\frac{7 \cdot 11}{2} = 38\frac{1}{2} = 38.5$$
