What does that mean Martina? When studying IT in 1995 onwards (I was 55 then) I needed algebra, indices, and probabilities and statistics - they were all rude words to me and I couldn't understand why we needed to play with the dice - I found logic and bits and bytes much easier to understand, but I can figure out anything in quilting :lol: I do most sums in my head or on paper and don't like calculators. I can build a computer (older style now 286-486+ because today's pcs configure themselves) but don't like playing with the remote control on tv :roll: We can do whatever we think is worth knowing about :thumbup:
