We can use a number line for ordering numbers and integers. Learn how to order numbers in few simple steps.

## Step by step guide to ordering integers and numbers

- When using a number line, numbers increase as you move to the right.
- When comparing two numbers, think about their position on the number line. If one number is on the right side of another number, it is a bigger number. For example, \(- \ 3\) is bigger than \(- \ 5\) because it is on the right side of \(- \ 5\) on number line.

### Example 1:

Order this set of integers from least to greatest. \(- \ 4, – \ 1, – \ 5, 4, 2, 7\)

**Solution:**

The smallest number is \(- \ 5\) and the largest number is \(7\).

Now compare the integers and order them from least to greatest:

\(- \ 5 \ < \ – \ 4 \ < \ – \ 1 \ < \ 2 \ < \ 4 \ < \ 7\)

### Example 2:

Order this set of integers from greatest to least. \(3, – \ 2, – \ 1, 6, – \ 9, 8\)

**Solution:**

The largest number is \(8\) and the smallest number is \(- \ 9\).

Now compare the integers and order them from greatest to least:

\( 8 \ > \ 6 \ > \ 3 \ > \ – \ 1 \ > \ – \ 2 \ > \ – \ 9 \)

### Example 3:

Order this set of integers from least to greatest. \(-2,1,-5,-1,2,4\)

**Solution:**

The smallest number is \(-5\) and the largest number is \(4\).

Now compare the integers and order them from greatest to least:

\(-5<-2<-1<1<2<4\)

### Example 4:

Order each set of integers from greatest to least. \(10,-6,-2,5,-8,4\)

**Solution:**

The largest number is \(10\) and the smallest number is \(-8\).

Now compare the integers and order them from least to greatest:

\(10>5>4>-2>-6>-8\)
