It's a TI-84 Plus that gives me large, negative, wrong answers when entering equations like

(15.8)^2 + (24.3)^2 - (18.6)^2 / 2(15.8)(24.3) = -65573.8112

while the actual answer is a decimal: "0.6435510757"

I hope that this is being caused by settings that I altered in " MODE " or
" Calc "

Anyone have an idea?
