It works just fine, but TI used to put more effort in even their simple models. It does not have a button to zero the memory.

Summary: Works as well as any handheld calculator. I just wish that entries placed into the memory were to disappear permanently when shutting the gadget off.
Summary: I bought a couple of other calculators in the past couple years but they were solar powered and I could not see the numbers in the display very easily.
Summary: I never can find a calculator when I need one so I just picked this up to toss in a drawer so I have a better chance of stumbling across one when the time comes.
