**Positive and negative integers :**

Positive numbers are numbers greater than 0. Positive numbers can be written with or without a plus sign.

For example, 3 is the same as +3. Negative numbers are numbers less than 0. Negative numbers must always be written with a negative sign.

Two integers are opposites if, on a number line, they are the same distance from 0 but on different sides of 0. For example, 5 and -5 are opposites. 0 is its own opposite.

The above situation is illustrated in the picture given below.

**Example 1 : **

Compare the integers -4 and 4

**Solution : **

Let us locate the two integers -4 and 4 on a number line and mark them.

Here, the positive integer 4 comes to the right of -4.

Therefore "4" is greater than "-4"

And -4 comes to the left of 4.

Therefore "-4" is smaller than "4"

**Example 2 :**

Compare the integers -1 and 1

**Solution : **

Let us locate the two integers -1 and 1 on a number line and mark them.

Here, the positive integer 1 comes to the right of -1.

Therefore "1" is greater than "-1"

And -1 comes to the left of 1.

Therefore "-1" is smaller than "1"

**Example 1 :**

Order the integers 1, -5, 5, 4, 0, -2, -1, 3 from least to greatest.

**Solution : **

Let us locate the integers 1, -5, 5, 4, 0, -2, -1, 3 on a number line and mark them.

From the above number line, write the integers from left to right to list them in order from least to greatest.

Thus, we get

**-5, -2, -1, 0, 1, 3, 4, 5**

**Example 2 :**

John recorded the following golf scores during his first week at a golf academy. Negative numbers represent scores below par, a standard score. In golf, a lower score beats a higher score.

Graph John’s scores on the number line, and then list the numbers in order from least to greatest.

**Solution :**

**Step 1 :**

Graph the scores on the number line.

**Step 2 :**

Read from left to right to list the scores in order from least to greatest.

The scores listed from least to greatest are

** –5, –3, –2, –1, 0, 3, 4**
