Inline calculations

[Brigden 0]

I would really like to see support for in-line calculations when writing notes like OneNote. In OneNote I can write e.g. 126/19= and when space is tapped the basic math is performed on the fly without having to reach for a calculator. In OneNote I find it annoying having to delete the equation afterwards (although less annoying than having to reach for a calculator) if I only want to keep the result though, so it may be useful to instead have a shortcut that brings up a calculation box and on Enter the result is placed into the note at the cursor position.
