In a number line the number increases going from left side to right side. If we move to the right side we are moving in the positive direction. If we move to the left side we are moving in the negative direction. In a number line any number to the left of another number is considered to be smaller than the number to its right. One can order the numbers by arranging them from smallest to the largest or the largest to the smallest.
To find the largest or smallest number in a set of numbers one has to compare each number with one another. In this section we will be learning more about how to compare numbers and the symbols used for that.
