dosxuk   10 #183 Posted March 13, 2012 If i was using it i'd go for 7. If you wanted to square the whole thing it would need brackets around the 3+2.  But if you apply your rule "BODMAS doesn't apply because there are no brackets, therefore calculate from left to right", you get: 3 + 2² = 5² = 25  Or are you applying another rule?

Waldo   96 #184 Posted March 13, 2012 My phone calculator agrees with me too.  As you type it in to a calculater, it performs each step as a distinct operation. So it would give an answer of 0. Share this post Link to post Share on other sites Share this content via...
HeadingNorth   11 #185 Posted March 13, 2012 The answer to the op is still 0. If you don't want to believe it or would prefer to ridicule or find fault please feel free.  If brackets aren't there,then they don't exist so BODMAS does not apply.  BODMAS always applies. The absence of brackets just means you start with "of", or if that doesn't appear either, you start with division and multiplication.

Lockjaw   11 #186 Posted March 13, 2012 As you type it in to a calculater, it performs each step as a distinct operation. So it would give an answer of 0.  Depends on the calculator. Many modern ones don't perform any part of the calculation until you press "=". I assume this feature has been developed in response to, for instance, the fact that this thread is now ten pages long.

If you don't want to believe it or would prefer to ridicule or find fault please feel free.  If brackets aren't there,then they don't exist so BODMAS does not apply. If its on a page discussing BODMAS it should be common sense that BODMAS will apply wouldn't you think? As are all the "trick" questions posed.  I'm not trying to trick or ridicule you Willman. It would be nice if you could refer to some evidence of BODMAS not being applicable where there are no brackets.  I can't believe something that important to the maths world, would not be written down somewhere, in some respected source.

HeadingNorth   11 #192 Posted March 13, 2012 The sum is 3 + 2squared, the square has never applied to the whole sum. That would need brackets.  You're contradicting yourself. Your argument of always going from left to right requires "3+2" equals five, "squared" equals 25. Share this post Link to post Share on other sites Share this content via...
