## 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 Add Integers Video

This math video tutorial in Taglish (mixed Tagalog and English) discusses the rules and strategies in adding integers. The rules that are easy to remember is that when you add two positive integers, the answer is negative. Also, when you add two negative integers, the answer is also negative. Watch the video or read How to Add Integers to know how to add positive and negative integers.

This video is a part of my collection of Taglish math videos in Sipnayan.

## 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.

2.) How to Solve Number Series Problems Part 1 discusses simple integer, letter, and fraction sequence.  » Read more

## How to Solve Motion Problems Part 4

In Part 1, Part 2, and Part 3 of the How to Solve Motion Problems Series, we have learned how to solve problems involving objects moving in the same direction as well as those which move toward each other. In this post, we are going to learn about objects which move on opposite directions. The method in solving this problem is very similar to the method used in Part 3 of this series.

We now solve the sixth problem in this series. » Read more

## How to Solve Motion Problems Part 3

This is the third part of the How to Solve Motion Problems Series, a part of the Word Problem Solving Series of Ph Civil Service Reviewer. In Part 1 and Part 2 of this series, we discussed objects moving in the same direction. In this part, we are going to discuss objects moving toward each other. We have already discussed four problems in the previous parts of this series, so, we solve the fifth problem.

Problem 5

A car leaves City A and travels towards City B at an average speed of 60 kilometers per hour.  At the same time, another car leaves City B and travels towards city A at an average speed of 70 kilometers per hour.
