Video: How to Subtract Integers

This math video is a supplement material How to Subtract Integers.  In this video, I have explained how to convert a subtraction problem into addition problem in order to simplify it. This way, you only have to master addition of integers.

The idea is that all numbers that are of the form a - b can be converted into a + (-b).  Therefore, any subtraction can be converted into an addition problem. Watch the video to understand this strategy.

How to Solve Number Series Tutorials

The “number series” tutorials of PH Civil Service review contains tutorials on methods and strategies used in solving number series problems. As I have mentioned in the teaser of this tutorials, the term “series” is technically wrong: what you are solving are really sequences. Although they maybe similar to many of you, to mathematics majors, they are very different.  In mathematics, series means sequence of sums. I will not go into details about this since this is irrelevant for the review. In this series of tutorials, mathematically, we will use the term “series” and “sequence” interchangeably.

1.) A Teaser on Answering Number Series Questions discusses a brief introduction to number sequence.
