Basic Math Examples

$N = \frac{1}{2} \cdot (n^{2} - n)$

Step 1

Apply the distributive property.

$N = \frac{1}{2} n^{2} + \frac{1}{2} (- n)$

Step 2

Combine $\frac{1}{2}$ and $n^{2}$ .

$N = \frac{n^{2}}{2} + \frac{1}{2} (- n)$

Step 3

Combine $\frac{1}{2}$ and $n$ .

$N = \frac{n^{2}}{2} - \frac{n}{2}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
