i was working on it a couple of weeks ago but on a different calculator.

so is it me or the formula i have?

so its a mortgage payment formula

M= monthly repayment

P = principal(amount borrowed)

T = term of loan

K = 1 +

__R__

100

R = interest rate

M =

__PKt__(

__K-1__)

12spaceKt-1

so for a £30K @ 8% over 25 years

Im inputting the formula (i used* for the power of)

(30000x1.08*25)/12)x(1.08-1)/(1.08*25-1)

now I was just checking the calculators functions and this is the example from the text

yet inputting the above gives a syntax error directed to the 1st *25 in the formula

am i missing something obvious here?

I know for some this will be basic stuff but its been many years for me
