Skill: Compare and order integers

To compare and order integers, use their positions on a number line:

• Numbers farther to the right are greater.
• Every positive integer is greater than $0$.
• $0$ is greater than every negative integer.
• For negative integers, the number with the smaller absolute value is greater. For example, $-2>-5$ because $-2$ is farther right on the number line.

Example: Order $-4,\ 2,\ -1,\ 0,\ 3$ from least to greatest.

1. Find the negative integers. Since $-4$ is farther left than $-1$,

$$-4<-1.$$

2. Place $0$ after all negative integers:

$$-4<-1<0.$$

3. Place the positive integers in order. Since $2$ is less than $3$,

$$2<3.$$

4. Combine the numbers:

$$\boxed{-4<-1<0<2<3}.$$

So, from least to greatest, the integers are $-4,\ -1,\ 0,\ 2,\ 3$.
