• When you combine like terms

• When you multiply or divide by a positive number

• f < 0.5

• f > 0.5

• f < 1.2

• f > 1.2

When do you have to flip the inequality symbol?

• When you add or subtract a negative

• When you multiply or divide by a negative number

• When you combine like terms

• When you multiply or divide by a positive number

What do we have to do when we multiply or divide a negative number when solving an inequality?

• Nothing, it is like an equation

• Flip the inequality sign

• just make it positive

• You cannot multiply or divide negative numbers

This inequality NEEDS to be FLIPPED because ​ (a)  

• you divide by a NEGATIVE number to solve

• you multiply by a NEGATIVE number to solve

• x is on WRONG side of the < > ≤ ≥ symbol
