Question
Using number line, how do you compare two positive integers?
Solution
We know that, on the number line, points to the right of zero are positive integers and points to the left of zero are negative integers.
Also, if move from left to the right on the number line, then number increases and if we move from right to the left on the number line, then number decreases.
If we compare two positive integers on the number line, then the number which is on the right of the other number, will be greater. e.g.
Here, we see that 3 is on the right of 1, so 3 is greater and 1 is smaller.
