Use multiplication, division, addition and subtraction and at least one set of parentheses to write an expression that simplifies to 7, 13, or 17. Do your work step by step and explain each step as you simplify the expression. Demonstrate the consequences of not using the proper order of operations by showing that other orders yield different answers

What's a shame is that this question is a graded problem from a college, and that the problem is not a difficult one to solve, and yet there is someone who (rather than working it out!!) has gone looking for someone else to work it out!
