Thanks! I use Desmos all the time so I don't know why I didn't think about using it. Thanks a ton!

Good luck with it, but what are SOLS? 

a_n=n²

For example: a₁=1² and 1² is 1

                      a₂=2² and 2² is 4

                      a₃=3² and 3²​ is 9

0.4 as a fraction is 2/5.

Are you trying to solve for a certain variable? You have to be more specific.

72-0 is just 72 because if you take nothing away from 72 you still have 72.

Hey Melody, how do you enter aswers in that format with fractions and exponents?

t(t​^3​​+2t^​2​​−4t+5)
