This Volume of tetrahedron calculator helps to quickly and easily solve any math problems.
It shows how to get there and every solution and even a graph , when possible! Really good for checking your work and finding where you made your mistakes. It can solv any mathematical problems within a few moment.
One thing that could maybe be a tad better is the "Show steps" that can only be used once, and then paying, try to use it, amazing app! [does not require a specific age] helps a lot with checking work.
Overall this was a pretty good app. Sometimes they'll let you look at it for free but the app is really good, and it's helping me get through Algebra 2😭. The examples are great and work. It is easy to manipulate and understand. If you know you suck at math or you just wanna confirm your answers, this app is the best way to go.
