In the previous post, I have mentioned that it is important for you to master basic mathematics. One of the basic skills that you should master is operations on integers. Luckily, I have finished writing all the tutorials and reviewers for all the operations on integers.  They are listed below.

1. How add Integers (Practice Test with Solutions, Quiz 1)
2. How to Subtract Positive and Negative Integers ( Practice Test with Solutions, Quiz 1)
3. How to Multiply Integers (Practice Test with Solutions , Quiz 1, Quiz 2)
4. Dividing Positive and Negative Integers (Practice Test  with Solution, Quiz)

Good luck and have fun. I will be posting the quizzes and PDF exercises soon, so keep posted.
