here is the question:(21 x 8) ? 4 + 60 - 17 =
In the place of the "?" you can substitute a straight verticle line like this "l" I dont know why its there or the question mark. It is an answer I have to give to win a gift certificate but the stupid line or question make doesnt make sense...but its there . Anyone with an answer?
My best guess is that it is a typo and it is supposed to be "/", i.e. division.
(21 x 8) / 4 + 60 - 17 =
= 168 / 4 + 60 - 17
= 42 + 60 - 17
= 102 - 17
= 85
