I'm looking for software that can serve as a replacement for a physical "scratch pad", on a Windows system with only keyboard and touchpad interfaces. This is intended to facilitate manual calculations, but not actually do any computation.

$\LaTeX$ is good for some things, but I haven't found an easy way to do things like vertical addition/subtraction/multiplication/division with the same speed & comfort as I might do on a scratch pad.

Excel and Notepad can serve the purpose, but they're a bit clumsy at it. Paint could do, but is not so great to use without a mouse.

Is there any purpose-built "scratch pad" software out there? Or, are there other workarounds I might not have thought of which work well on a laptop with no regular mouse?

I think you are in the wrong SE board. Your question is not a mathematical one. – Ittay Weiss Nov 14 '12 at 4:53
@IttayWeiss I posted the question in chat, and was told there are already similar questions for other mathematical software requests here - so, presumably, this would be acceptable. – Iszi Nov 14 '12 at 13:46
@IttayWeiss: Help Center > Asking says that questions about "software that mathematicians use" are on-topic. This appears to fall in that category. – robjohn Aug 23 '13 at 9:27

Microsoft Math has math handwriting recognition capabilities.

MS Math

A few other products claim similar functionality:

My problem with these, as with Paint, is that "handwriting" with a touchpad isn't exactly fun. – Iszi Nov 14 '12 at 2:05
Ah, you said touchpad. I was thinking touchscreen. – Emily Nov 14 '12 at 2:11
I'm searching for the same sort of thing - MS Math doesn't work, because it stubbornly refuses to simply let me write down what I need... It solves everything, which I don't want out of a scratch pad. Has anyone found any software that allows you to write mathematical equations nicely, in order to solve them manually? – PhoenixCodes Aug 23 '13 at 0:33

You might try Math-o-mir. I haven't used it myself but the site says:

The idea behind Math-o-mir was: "why can't I use my PC as simple as I am using pencil when writing mathematical equations?"
