The Civil Service Exam includes questions on integers. There may be questions involving integers as well as a flow chart which makes use of integers (more on that flow chart thing next time). Let’s start with the basics first.

**Integers** are zero plus all the positive and negative whole numbers (0, 345, -678, 43, -26, etc.). They can be represented on a number line with zero in the middle. To the left are all the negative integers and to the right are all the positive integers. Remember that integers do not have a fractional part.

Now we move on to** Basic Math Operations with Integers**. The table below shows how to add, subtract, multiply, and divide positive and negative integers (The table is taken from our soon-to-be-released Ultimate Civil Service Reviewer – to be launched this June).

[…] The Civil Service Exam will include questions involving integers – from basic math calculations to number flow charts. That being said, you have to be familiar with what integers are and how to add, subtract, multiply, and/or divide them. You have to know the rules that govern operations involving positive and negative integers. To know more about these rules, check our post: How to Add, Subtract, Multiply and Divide Positive and Negative Integers […]
