    This appears to be a nice calculator with one large flaw. You can't follow what your typing on the screen. For example if you are adding 6+5, you type '6' then '+', at which the '6' disappears, then '5' then '=' and the answer appears. While calculating 6+5 isn't difficult, it is almost impossible to keep track of a longer or complex calculation. For example, how do you type in and solve 6x(5-3)/7 + 4^3?

    the little expression on the top is to track the formula you typed in.
