Basic Math Examples

A n B = A

$A n B = A$

Step 1

Subtract

A

$A$ from both sides of the equation.

A n B - A = 0

$A n B - A = 0$

Step 2

Step 2.1

Factor

A

$A$ out of

A n B

$A n B$ .

A (n B) - A = 0

$A (n B) - A = 0$

Step 2.2

Factor

A

$A$ out of

- A

$- A$ .

A (n B) + A \cdot - 1 = 0

$A (n B) + A \cdot - 1 = 0$

Step 2.3

Factor

A

$A$ out of

A (n B) + A \cdot - 1

$A (n B) + A \cdot - 1$ .

A (n B - 1) = 0

$A (n B - 1) = 0$

A (n B - 1) = 0

$A (n B - 1) = 0$

Step 3

Divide each term in

A (n B - 1) = 0

$A (n B - 1) = 0$ by

n B - 1

$n B - 1$ and simplify.

Step 3.1

Divide each term in

A (n B - 1) = 0

$A (n B - 1) = 0$ by

n B - 1

$n B - 1$ .

\frac{A (n B - 1)}{n B - 1} = \frac{0}{n B - 1}

$\frac{A (n B - 1)}{n B - 1} = \frac{0}{n B - 1}$

Step 3.2

Simplify the left side.

Step 3.2.1

Cancel the common factor of

n B - 1

$n B - 1$ .

Step 3.2.1.1

Cancel the common factor.

\frac{A (n B - 1)}{n B - 1} = \frac{0}{n B - 1}

$\frac{A (n B - 1)}{n B - 1} = \frac{0}{n B - 1}$

Step 3.2.1.2

Divide

A

$A$ by

1

$1$ .

A = \frac{0}{n B - 1}

$A = \frac{0}{n B - 1}$

A = \frac{0}{n B - 1}

$A = \frac{0}{n B - 1}$

A = \frac{0}{n B - 1}

$A = \frac{0}{n B - 1}$

Step 3.3

Simplify the right side.

Step 3.3.1

Divide

0

$0$ by

n B - 1

$n B - 1$ .

A = 0

$A = 0$

A = 0

$A = 0$

A = 0

$A = 0$
