Activate Maths by doing the Maths problems provided in the book. If you're able to solve the problems with ease then you've understood the how to solve this math problem.
Start with the mid difficult ones if you get the solutions easily move on to the more difficult ones. If you have difficultly play with some of the easy one. If you're able to get 4 to 6 correct answers in a row there is hardly any point in doing more of the exercises once you've demonstrated you can do them move on to different problems.
