I'm with bluesun. It's an order of operations question and the correct answer is 20.
Order of operations is exponents/roots, then multiplication/division, then Addition/subtraction always work inside parentheses before working outside them. Let's restate the problem using parentheses to point to the first operations 4x4+4x4+4-4x4=
20.
ReplyDeleteOrder of operations, bitchez.
That was one answer.
DeleteThere was another just about as popular.

Let's restate the problem using parentheses to point to the first operations
4x4+4x4+4-4x4=
can be restated to be
(4x4)+(4x4)+(4)-(4x4)=
which is
16+16+4-16=
which is the same as
16+4 = 20
20 here too. (16)+(16)-(16)+(4). What the heck would anyone else say?
ReplyDelete20.....I'm trying to figure out what other answer would be the big one lol
ReplyDeleteAlthough I get 20, I'll bet most people don't remember order of operations and get 320.
ReplyDeleteYep- 320 was the other one.
DeleteI got twenty in about three seconds.
Please excuse my dear aunt Sally.
ReplyDelete20 is correct.
ReplyDeleteYep, higher math is done first.

Or plug it into an Excel cell if you don't believe me.

My answer is 20.
ReplyDeleteI got 320.
ReplyDeleteI must have been drunk the day they taught order of operations.
OoO... 20
ReplyDelete20. Please tell us what the other "popular" answer was.
ReplyDeletePrahaps of restated to be:
ReplyDelete1) (4x4)+(4x4)+(4)-(4x4)=20
2) ((((((4*4)+4)*4)+4)-4)*4)=320
