Basic Math Examples

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

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

Step 1

Apply the distributive property.

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

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

Step 2

Combine

\frac{1}{2}

$\frac{1}{2}$ and

n^{2}

$n^{2}$ .

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

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

Step 3

Combine

\frac{1}{2}

$\frac{1}{2}$ and

n

$n$ .

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

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

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

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