Self Checking Desmos Slides

Hi, I am trying to make a desmos that is self checking. However, when I type in the correct answer it gives Almost! Try Again. but when I copy and paste the correct answer it says Excellent!. What did I do wrong?

Try enclosing each value of solution in backticks (`) instead of quotes ("). That way, Desmos knows it is a Latex string.

PS - I like the seasonal theme!
