*In math, just like in life, not everything is equal.

​

*Inequalities are used to show that one value is not equal to another value.

​

*Inequalities are often used to make comparisons of two quantities.​

Inequalities

​

​Since we read from left to right,

> means "greater than" because the value on the left is greater than the value on the right.

​Since we read from left to right,

> means "greater than" because the value on the left is greater than the value on the right.

​

7 > 5 means "7 is greater than 5"

​

5 < 7 means "5 is less than 7"​

​

​n > 54

Since variables can represent any number, this says "any number greater than 54".

​

Solutions to this inequality are anything larger than 54, but not 54.​

Variables should always be written FIRST in the sentence.

​

​n ≤ 54

Since variables can represent any number, this says "any number less than or equal to 54".

​

Solutions to this inequality are anything smaller or equal to 54, such as 30; 54; 0; -300.

*There are an infinite number of solutions.​

1. Each symbol has a specific way to mark

   1. (open or closed circle)

2. The symbol determines which way to shade
