How to Learn Math
Well, after you see the answer keys above, you may need some tips about how to learn math. According to the Eurekly site, here are how to learn math for students.

 You have to practice a lot. Math is a skill which will develop only by being practiced over and over again. So, you can use your spare time to practice equations, exercises and basic arithmetic.
 You need to review your mistakes. Usually, mathematics is all about problemsolving. To be able to solve the problems, you have to apply different solutions until you find the correct one. If you get the wrong answer, you need to review your process and find the mistakes. By understanding where you went wrong, it can strengthen your skills and avoid making the same mistakes.
 You need to focus on concepts, not processes. You need to know that math is a sequential subject where you have to understand one problem thoroughly before you move onto the next. If you only know the process of an equation, you will find it harder to understand where it fits into solutions for different problems in the future.
