Neat little toolbox.

Does what I want, which is to compute naturally, i.e., 1 1 = 2 (NOT 1, ENTER, 1, ). But it does so much more. It anticipates the equation, giving you running results. So, for the equation 2 x 345, it will generate an intermediate result of 6, as soon as you enter "2 x 3". The intermediate result will change to 68, as soon as you enter the next digit "4". And the answer will change again to 690, as soon as you enter the final digit "5". Hit the equals sign and not only does that finalize the answer, but it automatically is saved in a scrolling memory feature. How neat is that! Its main shortcoming is that it is limited to single operations only. No hiearchy of functions and no embedded paranthetical expressions. Just simple equations. (However, it does allow you to directly manipulate memory items, so it can be used to evaluate multi-factor/multiple operand equations - but not very elegantly.). Bottom line: It does what I need a simple calculator to do. 5 stars.
