I ordered this for my grandaughter for HS math. This product requires codes and complicated entries for each function, making it frustrating for reasonable use. Attempts to reset failed. Even her Math teacher could not get it to function with any ease. Not recommneded.

The calculator is just the one I wanted and when they said it would take 5 to 10 days to ship I thought that was just fine, gues what , It arrived the very next day less than 24 hours after I ordered it,Thanks, Overstock

This calculator is so easy to use. I love it. I was a little disappointed to find I could have purchased it for less money, but overall an excellent purchase!
