Math Equation Writer
I’d like to be able to enter math equations in text with special characters like in Microsoft word. With special characters and symbols. I use good notes for engineering.If you look a word, it has equation, and symbols, subscripts and super scripts. That would be great.

MathType is an application that allows you to use mathematical equations and formulas in various office programs. Formulas created in MathType can be inserted into Microsoft Office documents, OpenOffice, Adobe InDesign, etc. I needed the math equation program in the college I went to because of a wellwritten essay using college paper editor https://www.essayedge.com/collegeessayediting/ . If you want to save an equation you found on the internet  why waste time and rewrite it? Copy it to the clipboard and paste it into the program window with MathType.
