note: PLEASE MAIL YOUR REPLY TO jeffq@gorn.santa-cruz.ca.us (or @deeptht - it all ends up at gorn.) I am in search of a calculator which boasts 'solve for x' as its main feature; in other words, something really cheap that can do +-X/, powers, sq. root, and FRACTIONS, as well as solve for x in complex polynomials. This is for my son in high school and I don't want to go broke purchasing some gem that has on-screen graphing and a special subdivisory keypad that only the top mathematicians at NASA would even look at. I have been told about something like 'educalc' or 'educomp' that sells handheld cal's for lower prices that an average store - the # for the above would also be wonderful. Thanks! -jq

I don't know what you mean by really cheap but I do suggest that the calculator your son would be most pleased with is the HP 27S. This calculator will perform all of the functions your son will need for high school level classes and the HP solve function will solve for x in any equation. It is also an algebraic mode machine so it will be easy for him to learn to use. I have purchased many HP 27S calculators as gifts for my high school level relatives and they were all very happy with them. It is also prestigious to own the quality of HP. These calculators list for something around $79. but I am sure you can find them for less at discount educational retailers. I would buy HP calculators even if I didn't work for the company because they are the best.
