Integers - Basics, Properties, Applications

As learned in the previous chapters, numbers that start with Zero are called 'Whole Numbers', on the other hand, numbers that come naturally, such as 1,2,3, and so on are called 'Natural Numbers'. But what if we tell you that there are numbers that are placed before zero? Baffled? Don't worry. There are a group of numbers that are placed before the whole and natural numbers. These numbers are identified as 'Negative Numbers'. The combination of all positive and negative numbers are called 'Integers'. Why is that so? Integers come with different properties that help us in their calculation. For instance- one of the properties of integers is - Closure property. It states that the sum of integers always gives out an integer. Confused? Don't worry, let us watch these videos and understand these properties in detail.
