i am a circuit design engineer and happen to love rpn, as i owned an hp-28s for 15 years until the battery cover could not be glued shut anymore (the calculator still works fine, but i don't feel

i like it especially for trips and outside activities when i can do quite useful mathematical explorations that i don't normally have time for at home or in the office with my busy schedule.

not that there's that much software out there for hp calculators, as compared to ti models -- there's even more stuff for my not-permitted-in-most-classrooms ti-89 than there is for my cherished hp

it addresses most of the complex math problems.

i can't confirm this fact as of yet, but it uses 4 aaa batteries as well as a lithium backup battery to be used as a backup while changing the main batteries.2) most high schools require ti units,

hp sets the standard for engineering calculators.
