It does not even make an addition.<br \/>\n&nbsp;<\/p><\/blockquote>\n<p style=\"text-align: justify;\">That problem is very common and easy to solve. First of all, I tell you how you should have changed the batteries in case you have not done it yet, to make you know by the next time.<\/p>\n<p style=\"text-align: justify;\">The calculator has 2 big batteries (CR2032) that are the ones that make the calculator work, and a small one (CR1220) which is the one that saves the memory when the battery is changed. You have these different batteries to have a backup battery when changing, not to lose your information. Then you have to change just a battery, the big ones or the small ones, not the three at the same time. Once you are done with one, you can change the other.<\/p>\n<p style=\"text-align: justify;\"><!--more--><\/p>\n<p style=\"text-align: justify;\">To solve your problem, with the calculator turned on, push with a needle, the hole placed back, where the letter \u201cP\u201d. Doing this it will not delete the\u00a0programs you have on the Casio, and I guess with this it would be enough to solve your problem. This button works to take away the static electricity.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify;\"><img decoding=\"async\" class=\"aligncenter size-full wp-image-1532 lazyload\" data-src=\"https:\/\/www.casio880.com\/wp-content\/uploads\/2014\/06\/rester-estatica-casio.jpg\" alt=\"rester-estatica-casio\" width=\"600\" height=\"240\" data-srcset=\"https:\/\/www.casio880.com\/wp-content\/uploads\/2014\/06\/rester-estatica-casio.jpg 600w, https:\/\/www.casio880.com\/wp-content\/uploads\/2014\/06\/rester-estatica-casio-510x204.jpg 510w, https:\/\/www.casio880.com\/wp-content\/uploads\/2014\/06\/rester-estatica-casio-300x120.jpg 300w\" data-sizes=\"(max-width: 600px) 100vw, 600px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 600px; --smush-placeholder-aspect-ratio: 600\/240;\" \/><\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify;\">If it does not work, you have to push with a needle the hole in the front \u201cALL RESET\u201d.
