Question

Using number line, how do you compare one positive and one negative integer?

Answer 1

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 one positive and one negative integers on the number line, then a positive integer is always greater than the negative integer. e.g.

Here, we see that 2 is on the right of –1, so 2 is greater and –1 is smaller.
