Last year I tried replace my laptop with an iPad. I’m a math teacher and I needed to be able to create and edit word documents that contained equations…lots of them. I found a few apps (like MathBot) that would allow me to create equations. The downside with these type of apps is that they are not word processors. You have to export each equation as a photo or PDF, then you have to paste it into a document you’ve created in another app, then you have to adjust the size and if you have several equations on the same page it is nearly impossible to get them all a uniform size. And there is no editing the equations once they’ve been exported.
It’s a lot of work, and the end product is not that great.
I continued to look for a word processor with a built-in equation editor. I nearly bought a Microsoft Surface RT because it came with MS Office, but the price ($599) convinced me to keep looking for a more affordable option.
I found the perfect solution: Refurbished iPad 2 ($319) + CloudOn (free).
CloudOn is an office suite with built-in equation editor, just like MS Office.
