PEMDAS

PEMDAS

Can you write me an equation one way and change the solution by adding or taking out parentheses? Show it both ways with the answers. Work it out step by step and line by line just like we do in class. Make sure to put your first name at the end of your post. Be sure to show EVERY step!




Example:  6*10+4=64                or               6(10+4)=84
                60+4=64                                      6(14)=84
