[QUOTE="Hound dog, post: 548934, member: 84"] Janet, I also come from those dark ages. lol And soon as they start giving instructions for doing the problems with the calculator.......I'm totally lost. I think they're cheating the kids to teach them to do the math that way at the very beginning. We're teaching them to be overly reliant on gadgets to do the real work for them and to not really think about it all the way through. When mine were young, they weren't allowed a calculator for homework (I didn't give a darn what the teacher did/didn't want) and I refused to buy them one for class. I don't think they even saw one until college.....unless the teacher had some in the classroom. I watched in my college algebra course grown people reduced to tears because using the calculator only made it ten times more confusing. (didn't help they didn't know how to use the calculator properly either.......which included me) Bff and I had to tutor classmates on the steps worked out on paper (heaven help you if you tried to follow professor skip ten steps) .......and bff tutored all of us on wth the buttons on the calculator did. Not that teaching me a calculator did much good. If I tried to use it I couldn't work the problem. Since the professor had problems worded such you had to use it......well, there is a reason I barely passed the course and it wasn't all Traumatic Brain Injury (TBI) related. (or I don't think it was as I wasn't the only one having issues.) I'm weird. I learned math pre kindergarden as money.
