bobpursley,
The language of Algebra is precise, and built into it is an expectation that the user will follow the order of operations rules. Going from left to right is not in those rule, and can lead to erroneous results.

Michelle,
You have to follow the Order of Operations. Try this phrase out. "Please Excuse My Dear Aunt Sally" PEMDAS
P=parantheses E= Exponents M=Multiplication D=Division A=Addition S=Subtraction
It sounds stupid but it works.

Discussion Question 1 Please post a 150300word response to the following discussion question by clicking on Reply. Be sure to answer completely. Systems of equations can be solved by graphing or by using substitution or elimination. What are the pros and cons of each method? Which method do you like best? Why? What circumstances would cause you to use a different method? Consider responding to your classmates by indicating pros and cons they may not have considered or persuading them to see the value of the method you like best (if you chose different methods). Describe situations in which you might use their methods of solving.
