Thanks a lot I was struggling how to calculate this type of math by using scientific calculator but I couldn't. Now it will be really easier for me to solve this type of problem.
SCHOOL told me to buy fx-991es, they said its a new model that will help us take on more complicated math, they lied, this video was posted 9 years ago, this calculator came out 9 years ago
Omg you are an actual lifesaver, I have a CPA accounting exam in two days and was panicking over having to calculate this manually and not realising I could do this with a scientific calculator until now!
