Basic Math Examples

P = 7000 {(1 + 0.05)}^{- 12}

$P = 7000 {(1 + 0.05)}^{- 12}$

Step 1

Add

1

$1$ and

0.05

$0.05$ .

P = 7000 \cdot {1.05}^{- 12}

$P = 7000 \cdot {1.05}^{- 12}$

Step 2

Rewrite the expression using the negative exponent rule

b^{- n} = \frac{1}{b^{n}}

$b^{- n} = \frac{1}{b^{n}}$ .

P = 7000 \cdot \frac{1}{{1.05}^{12}}

$P = 7000 \cdot \frac{1}{{1.05}^{12}}$

Step 3

Raise

1.05

$1.05$ to the power of

12

$12$ .

P = 7000 \cdot \frac{1}{1.79585632}

$P = 7000 \cdot \frac{1}{1.79585632}$

Step 4

Divide

1

$1$ by

1.79585632

$1.79585632$ .

P = 7000 \cdot 0.55683741

$P = 7000 \cdot 0.55683741$

Step 5

Multiply

7000

$7000$ by

0.55683741

$0.55683741$ .

P = 3897.86192724

$P = 3897.86192724$
