It depends on what functions your calculator has. However it is a scientific calculator that you really should have, not a financial calculator. It seems that you understand what the workings are from what you have typed.

Yes, you are right. Texas Instrument TI30xs that is used in ACCA Computer-based exam is a scientific and not financial calculator. I don't know how to get from this: ($R / 1·0220^1) + ($R / 1·0251^2) + ($R / 1·0284^3) + ($R / 1·0325^4) + ($R / 1·0362^5) + ($100 / 1·0362^5) = $100 to... 4·5665R + 83·71 = 100 R = $3·57 Should I use a scientific calculator or just math workings to solve this? Thank you in advance.

R / 1.0220^1 = R x 1/1.0220 = R x 0.9785 R / 1.0251^2 = R x 1/1.0251^2 = R x 0.9516 R / 1.0284^3 = R x 1/1.0284^3 = R x 0.9194 Do the same for all of them, add up all the terms with R in them and then you get to the answer you typed above :-)

Thank you Sir.

You are welcome :-)
