Basic Math Examples

$a n = 2 n - 1$

Step 1

Divide each term in

$a n = 2 n - 1$ by

$n$ .

$\frac{a n}{n} = \frac{2 n}{n} + \frac{- 1}{n}$

Step 2

Simplify the left side.

Step 2.1.1

Cancel the common factor.

$\frac{a n}{n} = \frac{2 n}{n} + \frac{- 1}{n}$

Step 2.1.2

Divide

$a$ by

$1$ .

$a = \frac{2 n}{n} + \frac{- 1}{n}$

$a = \frac{2 n}{n} + \frac{- 1}{n}$

$a = \frac{2 n}{n} + \frac{- 1}{n}$

Step 3.1.1.1

Cancel the common factor.

$a = \frac{2 n}{n} + \frac{- 1}{n}$

Step 3.1.1.2

Divide

$2$ by

$1$ .

$a = 2 + \frac{- 1}{n}$

$a = 2 + \frac{- 1}{n}$

Step 3.1.2

Move the negative in front of the fraction.

$a = 2 - \frac{1}{n}$

$a = 2 - \frac{1}{n}$

$a = 2 - \frac{1}{n}$
