In this Section:
In this section, we learn about a new group of numbers known as the integers. To do this, we introduce a new concept known as an opposite. The opposite of a number, or additive inverse of a number is found by changing the sign of the number. We then move on to learn about the integers, which consist of the whole numbers and their “opposites”. The integers: …,-3,-2 -1,0,1,2,3,… We will also learn to compare and show the relative size of two or more integers using a number line and the inequality symbols > & <. Lastly, we will learn how to simplify when one or more "-" symbols are present.
