Great Work!
Incorrect
Rules for Multiplying Integers
First, plug in the given values`x=6`
`y=5``x``y````y` `=` `(``6``)(``5``)(``5``)` Next, solve the multiplication.`6(5)``(5)` `=` `30` `(5)` Recall, Next, recall the rules for subtracting integers`30````(````5)` `=` `30``+``5` Recall, Now, solve using the number lineStart at `30`, then since `5` is positive move right `5` places`30` `+5` `=` `30+5` `=` `25` `25`
