I really like free stuff! I'd like to share a couple of things with you for math help that are free.
The first one is an app called Photomath. You take a picture of a math problem, and not only do you get the answer, it animates the steps for you! Here is their website with links to both app stores:
The second resource is Khan Academy. This guy is just very good at explaining and illustrating math concepts. Check them out at https://www.khanacademy.org/
Hope this helps someone who is pulling their hair out trying to do math homework!
