Ti 84 plus calculator help!?

Question

my calculator has never done this before but I'm sure I pushed a button I wasn't suppose to. anytime I put anything into the y= it says dim: invalid demensions. I have a math test monday so I need to fig it out please help!

Answer 1

just reset teh calulator. i think its 2nd + where it says mem in blue and u click "all" or something like that and then clear it.

Answer 2

push 2nd and then hit y=

pick the selection "plots off"

click enter and it will say "Done"

see if it works.

when it says invalid demensions it means your stat plots are on.
