I read the forum rules regarding posting strictly in the format laid out; I hope this is a legitimate post. Thanks for understanding! 1. The problem statement, all variables and given/known data As a Calculus II student in high school, I have been in increasing need of a means to create calculus expressions that can be emailed or manipulated digitally. Would any of you experienced forum members have any suggestions for me? 2. Relevant equations Free, online or downloadable, calculus expression-maker tool. 3. The attempt at a solution I've searched online for Latex editors, as I've heard that these are used for this purpose. However, I was unable to find a free solution. I've tried to scan handwritten expressions, but this process takes too long and the resulting JPG is hard to manage once I get it onto the computer. I also thought of Wolfram Alpha, but was unable to use it to make custom expressions. P.S. I just noticed your "Quick Symbols" box; what tool is this based on?
