Writing Inequalities 2-3
2 < 7 and 7 > 2 are two inequalities that state the relationship between the numbers 2 and 7
2 < 7 reads 2 is the less than 7
7 > 2 reads 7 is greater than 2
The symbols < and > are called inequality symbols.
The point of the number line that is paired with a number is called the graph of that number.
Check out the graph on page 39 of our textbook.
Looking at the graph of numbers, we see that the larger number will be to the right of the smaller number.
A number n is between 6 and 12 would be 6 < n < 12 or 12 > n > 6
