DM-15L Review

[n1msr]

Very interesting post. I will try to follow the progress you post.

I was encouraged to study further maths at A Level in the UK simply because I wanted to know more about hyperbolic functions that appeared on my Texas SR-50A calculator. I was the only one at school with programmable calculators and of course once it was known that there was no equals key, the calculator was safe ;-). I had an HP-67, although I had a TI-57 before that, until an avuncular neighbour showed me his HP-25C and RPN.

10 years old is very young to be using the 15L but thats no bad thing. Maybe you will need to buy a calculator later on that meets the school requirements, but even knowing that there are other ways of doing things (the DM15L) is a good lesson.

Best of luck and kudos to your kid who is prepared to give it a go!
