Only performs simple calculations

This is exactly the calculator I thought I was looking for because I was so insanely tired of having to memorize the number the calculator showed because it disappeared to the back once I clicked on the webpage to enter it into my homework. It does perform this task of always staying in the front which is very nice and I guess technically it does exactly what it says it does, but I bought it with the expectation that pretty much every calculator should be a scientific one or at least perform functions such as square roots, but this literally only does +/-/division, etc., so I was definitely disappointed.
