When teaching with technology, we want to teach mathematics, but we cannot avoid teaching software as well. In a similar way, a car is a means of getting from A to B, but you cannot make the journey without a driver's license. I discuss my experience of getting from x to y using Maple and Matlab. In both cases, I have collected the places where students most often crash and I have developed teaching material to set up buffers before they arrive. For example, in Maple there are differences between expressions and functions; in Matlab [1,2]/[4,5] is different from [1,2]./[4,5].
