The Operations on Integers Series

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

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