Question

$$(-10-10)\div\xi-10-(-10-10)$$

Evaluate

$10-\frac{20}{\xi }$

Short Solution Steps

Subtract $10$ from $-10$ to get $-20$.

$$\frac{-20}{\xi }-10-\left(-10-10\right)$$

To add or subtract expressions, expand them to make their denominators the same. Multiply $10$ times $\frac{\xi }{\xi }$.

$$\frac{-20}{\xi }-\frac{10\xi }{\xi }-\left(-10-10\right)$$

Since $\frac{-20}{\xi }$ and $\frac{10\xi }{\xi }$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{-20-10\xi }{\xi }-\left(-10-10\right)$$

Subtract $10$ from $-10$ to get $-20$.

$$\frac{-20-10\xi }{\xi }-\left(-20\right)$$

The opposite of $-20$ is $20$.

$$\frac{-20-10\xi }{\xi }+20$$

To add or subtract expressions, expand them to make their denominators the same. Multiply $20$ times $\frac{\xi }{\xi }$.

$$\frac{-20-10\xi }{\xi }+\frac{20\xi }{\xi }$$

Since $\frac{-20-10\xi }{\xi }$ and $\frac{20\xi }{\xi }$ have the same denominator, add them by adding their numerators.

$$\frac{-20-10\xi +20\xi }{\xi }$$

Combine like terms in $-20-10\xi +20\xi $.

$$\frac{-20+10\xi }{\xi }$$

Expand

$10-\frac{20}{\xi }$

Short Solution Steps

Subtract $10$ from $-10$ to get $-20$.

$$\frac{-20}{\xi }-10-\left(-10-10\right)$$

To add or subtract expressions, expand them to make their denominators the same. Multiply $10$ times $\frac{\xi }{\xi }$.

$$\frac{-20}{\xi }-\frac{10\xi }{\xi }-\left(-10-10\right)$$

Since $\frac{-20}{\xi }$ and $\frac{10\xi }{\xi }$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{-20-10\xi }{\xi }-\left(-10-10\right)$$

Subtract $10$ from $-10$ to get $-20$.

$$\frac{-20-10\xi }{\xi }-\left(-20\right)$$

The opposite of $-20$ is $20$.

$$\frac{-20-10\xi }{\xi }+20$$

To add or subtract expressions, expand them to make their denominators the same. Multiply $20$ times $\frac{\xi }{\xi }$.

$$\frac{-20-10\xi }{\xi }+\frac{20\xi }{\xi }$$

Since $\frac{-20-10\xi }{\xi }$ and $\frac{20\xi }{\xi }$ have the same denominator, add them by adding their numerators.

$$\frac{-20-10\xi +20\xi }{\xi }$$

Combine like terms in $-20-10\xi +20\xi $.

$$\frac{-20+10\xi }{\xi }$$
