An equation that is true for every value

Thank you guys for everything you do. A great app. Thank you for making this app, It's really useful for me and to people who are staggering with math. So easy to use, it's perfect when it comes to double checking your work, or doing corrections, has gotten me through some problems.

Great for help with Pearson's mymathlab frustrations, good stuff tho, really helpful in solving math problems, I honestly love it and for sure benifit much from it.
