But a possible introduction with bits can be a parallel with open/close electric circuit, and this is really not a math perspective :) This can come later with pratical situation : . X windows is in 16 bits mode, what does it mean ? So you can introduce some combinator math . I have a bit representation of a number, what does it mean in decimal number ? So you can lead to a reflexion on how are represented numbers and how you decompoe them in their base (2 in this case) . You can also introduce Euclide divsion to convert from base 10 to base 2 But in most case, only the first point may be useful to computer users. From this exemple, you can see how I like to teach math, from a pratical situation leading to a more abstract one. Hope it helps. Hilaire
