I’m in math 1324 (math for business and social sciences)and sorta need help with my scientific calculator.

Question

My calculator is a TI 30xa and I’m using it for my math 1324 class. One of the things we learned about today was compound interest and we learned the formula for it which was A= P (1+ r/n)^nt. I guess my question is how do I raise my equation to the power of whatever number I have because every time I try to type out the formula on my calculator, it gives me a completely different answer. I just need a refresher since the last time I used a scientific calculator was ages ago and I’m sort of bad at math lol.

Any help would really be appreciated.

Answer 1

I don't have that specific model but in any scientific calculator, you need to use brackets to help it understand what to do first. So, input your expression as P((1+ (r/n)) ^ (nt)) (Observe the brackets). Press enter and you should have the correct answer.

I understand your concern over math class. Please check your chats once.
