pmt always negative
type 0 = at the end of the period
type 1 = at the beginning of the period
Describe the PV function.
=PV(rate,nper,pmt,[fv],[type])
look at pmt/how it’s compounded for rate and nper
Describe the PMT function.
=PMT(rate,nper,pv,[fv],[type])
look at type of payment for rate and nper

Describe the LEN function.
returns number of characters
=LEN(text)
Describe the MID function.
