# How to solve compound interest on ti-83 - Texas Instruments TI-83 Plus Calculator

I reccently had the same problem, but I have a Ti-84 Plus,and I am disgusted by how poorly this matter is covered by Texas Intruments. Esp. since the solution is rather simple.

The antilog key is [2nd] [log] or the 10^x. On your screen it should apear as 10^( and then you just input the value that you want to find the antilog of.

When used to solve pH problems remember to input the pH value as a negative number, since pH= -log[H+] then [H+]= antilog(-pH).

Hope that helped))))) ^^

Hello,
Some old junk is in memory. Reset the memory to defaults and everything will be fine. It is a good practice to clear memory before a new calculation.
To reset memory
Press [2nd][MEM][7:Reset][1:All ram][2:Reset] [EMTER] . Clear screen and enter the functions you want to graph.
Hope it helps.

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.
