Hi,
I've got the first version of OneNote showed on this
list. Looks like the normal version and not the OneNote for Windows 10 version.
I found a guide to solve equations for the windows 10 version
here, but I cant seem to find this on the normal version?
Also, is it possible to quick draw a straight line? In some drawing apps you can just draw a line, and hold, and it'll draw a straight line.
