Well, if you read them both out loud, they sound the same. Don’t be fooled though! They are NOT the same. (-5) squared means -5 is multiplied by -5 so you get 25. That would be + 25. Right?
-5 squared (without parenthesis) means that 5 is squared. The negative is just sitting there in front of the 5 and it just continues to sit there. You get 25 when you square 5…..and with the – sign still sitting in front, you finally get -25.
This is a tricky one! Wouldn’t you say? Help your friends with this. I guarantee you lots of them don’t get it. The best way to learn something is to teach it to someone else.
