1. Inequality Signs < means “is less than”  means “is less than or equal to” > means “is greater than”  means ”is greater than or equal to” Reading Inequalities 1. 3 < n < 9 n is greater than 3 but less than 9. 2. 4  n < 7 n is greater than or equal to 4 but less than 7. 3. -2  n  1 n is greater than or equal to -2 but less than or equal to 1. 6 Always point to the smaller amount !

2. Read the following inequalities 1. 0 < n < 3n is greater than 0 but less than 3. 2. -5  n < 2 n is greater than or equal to -5 but less than 2. 3. -7  n  -1 n is greater than or equal to -7 but less than or equal to -1. 4. x > 9 x is greater than 9 5. x > -1 x is greater than -1 6. p  6 p is greater than or equal to 6 7. a  - 4 a is greater than or equal to - 4
