MA001 Unit 1 Homework 0.4 Properties of Algebra


I am having a problem with question 17 I have tried to get the solution 36, 5 or 6 times. I cannot for the life of me figure out how they got 36. I believe I am following the Order of Operations each time I just keep getting the same answer 31, If anyone can assist me I appreciate the help.


31 is correct. Looks like the textbook author (or some lucky grad student helping with the textbook) missed the “minus 5” term.

I have logged in our textbook errata for a fix in new versions of the pdf.


Thank you for the help.
