Due on Thursday – post to discussion thread · What are the steps of the order of operations? Why is it important that you follow the steps rather than solve the problem from left to right? Write an expression for your classmates to simplify using at least three of the following: (a) Groupings (parenthesis, brackets, or braces), (b) Exponents, (c) Multiplication or division, and (d) Addition or subtraction. Consider participating in the discussion by simplifying a classmate’s expression, showing how the expression would be incorrectly simplified if computed from left to right, or challenging the class with a complicated expression. Respond to your initial post and provide your classmates with the answer to your expression.

Write an expression for your classmates to simplify using at least three of the following: (a) Groupings (parenthesis, brackets, or braces), (b) Exponents, (c) Multiplication or division, and (d) Addition or subtraction. The steps of order of operations are PEMDAS. They stand for parenthesis, exponents, multiplication, division, addition, subtraction. It could also be PEDMSA, because multiplication not has to go before and same with addition and subtraction. If you do from left to right, you will get a completely different answer which does not work out. 2x3+ (3+5)2 2+3x3/6 Answer: 37.5...
