casio calculator help!! a level maths

was doing linear interpolation, just typing simple numbers, and it was giving me such a big number, i tried twice, then i left my calculator on the side for a few mins, tried again and it gave me the right answer. i literally typed the same thing, so my calculator was giving me wrong answers before for no reason! is it malfunctioning or what? thxx

either your calculator is malfunctioning or you are, there's no real way to tell which it is without watching you
