Description

Work with numbers vertically like you wouldwith pencil and paper.

I caught myself doing math on scratch paper, then using an appto calculate the answer. It struck me, "What am I using pencil andpaper for when I have a pocket super computer?"

Something was lacking in the standard calculator interface, or Iwould not have needed pencil and paper. Sketchpad Calculator is anattempt to fix this problem. It is similar to most calculators, butarranges the problems vertically and displays a constantly visiblehistory.

The killer feature is the ability to touch any number on thescreen to insert it into the current calculation. With traditionalcalculators, I was frequently re-entering numbers that I had justentered or calculated. Typing the same numbers over and over is notonly a waste of time, but an unnecessary source of errors.

There is no "Clear", "Clear All", or "CE" (whatever that is)button needed to remove previous operations. With SketchpadCalculator, what you see is what will be calculated. There is nomystery math. But what if you need to erase a calculation? Youdon't. Just move on and enter the next one.

There are no memory buttons needed either. All the memory yourequire and more is on the screen as part of the scrollingcalculation history.

The $ button is something new, but they way it works is simple.If any term in a calculation contains a dollar sign, then itsresult will be rounded to the nearest penny.

Speaking of rounding, if any term in a calculation usesscientific notation, then the result will be rounded to the properprecision: the number of significant figures in the least preciseterm.

The % button can be used to add a percent sign to the left orright of any non-currency number as a shortcut for "divided by100." (÷ 100)
