TVM: (1/EXPM1(N*LNP1(I))*(PV+0*PMT+FV)+PV)*I+PMT=0

Curiously, if I expand the expression, cut/paste to calculator:

1/EXPM1(N*LNP1(I))*(PV+0*PMT+FV)*I+PV*I+PMT

All I get is 1, not the string.

Looking further, "E" caused the parsing issue.
"Everything" --> <Not a Number>
"1+E" --> 1
"1-E" --> 1
"1*E" --> 1
"1/E" --> 1

If I paste this equation while in the equation editor, the whole equation is perfectly recognized.
Do you mean that you tried to paste this equation in the stack ? In that case it is normal that it is parsed as a number...
