Calculator doesn't work

Some students report that the online TI-30 XS calculator doesn't work if they can't enter the Quadratic Equation formula. The calculator works all the time, but you need to know how to operate it.

So, If it happens to you, please ensure that a calculator is in the Math Print mode so that you can enter fractions.
