# Can you help me with a little algebra?

I know you can use a calculator but I want to be able to calculate a mortgage without.

The correct answer is $ 1,199.10

30 year mortgage at a 6% interest rate with a $ 200,000 loan.

Here is a link to the formula

Here is what I bashed into my calculator

200 000 * 0.0005 = 100

0.06 / 12 + 1 = 1.005

1 – 1.005 = -0.005

-0.005 – 12 * 30 = -360.15

100 / -360.15 = -260.15

What did I do wrong?

I already have the algebra I just don’t know how to interpret it.
