Solve 5-10+0.4+10^2-(5*5+0.4*5^2)=

$$5-10+0.4+ { 10 }^{ 2 } -(5 \times 5+0.4 \times { 5 }^{ 2 } )=$$

Evaluate

$$60.4$$

Solution Steps

Subtract 10 from 5 to get -5.

$$-5+0.4+10^{2}-\left(5\times 5+0.4\times 5^{2}\right)$$

Add -5 and 0.4 to get -4.6.

$$-4.6+10^{2}-\left(5\times 5+0.4\times 5^{2}\right)$$

Calculate 10 to the power of 2 and get 100.

$$-4.6+100-\left(5\times 5+0.4\times 5^{2}\right)$$

Add -4.6 and 100 to get 95.4.

$$95.4-\left(5\times 5+0.4\times 5^{2}\right)$$

Multiply 5 and 5 to get 25.

$$95.4-\left(25+0.4\times 5^{2}\right)$$

Calculate 5 to the power of 2 and get 25.

$$95.4-\left(25+0.4\times 25\right)$$

Multiply 0.4 and 25 to get 10.

$$95.4-\left(25+10\right)$$

Add 25 and 10 to get 35.

$$95.4-35$$

Subtract 35 from 95.4 to get 60.4.

$$60.4$$

Factor

$$\frac{2 \cdot 151}{5} = 60\frac{2}{5} = 60.4$$
