FoxFighters Posted May 30, 2011 Share Posted May 30, 2011 Can you solve it? 5+5x5=................. Is it 50 or 30??? Holly Quote Link to comment Share on other sites More sharing options...
Geoid Posted May 30, 2011 Share Posted May 30, 2011 BODMAS Brackets, Orders (powers and square roots), Division, Multiplication, Addition, Subtraction. 5X5 = 25 25+5 = 30 Quote Link to comment Share on other sites More sharing options...
jimnpaula Posted May 30, 2011 Share Posted May 30, 2011 30 you do the multiplication first, then the addition. If the addition is to be done first then it needs to be put in brackets ie: (5+5)x5 P Quote Link to comment Share on other sites More sharing options...

freddie Posted May 30, 2011 Share Posted May 30, 2011 (edited) 30 if you use BIDMAS. (Brackets, Indices, Division, Multiplication, Addition and Subtraction) 5x5,then+5=30. Edited May 30, 2011 by Guest Quote Link to comment Share on other sites More sharing options...

kerryegg Posted May 30, 2011 Share Posted May 30, 2011 But if you used pieces of cake instead of just numbers would the answer be different? Quote Link to comment Share on other sites More sharing options...

Sheilaz Posted May 30, 2011 Share Posted May 30, 2011 Nah start at the start and end at the end 50 I'm completely with you Plum! Phew, I thought that too, I'm sure we did it that way. Perhaps we didn't have so many numbers, way back then (back in the day). PS. Surprisingly, ES thought 50 too, and also YD (who has a maths tutor starting from tomorrow! ), and we all thought there'd be some brackets on the 5 x 5 to make 30. I'm going to listen in on the tutoring. Quote Link to comment Share on other sites More sharing options...
WitchHazel Posted May 30, 2011 Share Posted May 30, 2011 30. Multiplication and division first. It's only 50 if brackets are used like this: (5+5)*5 Quote Link to comment Share on other sites More sharing options...
Sheilaz Posted May 30, 2011 Share Posted May 30, 2011 Yes, I meant to say, I can see the answer for the OP is 30, I just think maybe I was around before BODMAS was invented. Or I was listening to the top 30 on my transistor radio. Quote Link to comment Share on other sites More sharing options...

bluekarin Posted May 30, 2011 Share Posted May 30, 2011 I feel as if I have stumbled into a parallel universe! which is excatly how I felt at the weekend when ED (in year 9) told me about it If you have to do it a specific way, why can't the sum just show that? It's like everyone is making it up and I always will get the answer wrong Quote Link to comment Share on other sites More sharing options...
Sam Posted May 30, 2011 Share Posted May 30, 2011 Questions like this have been going around on facebook for a while now. I doubt people in the maths world would usually write them like that, it's just to catch people out. BIDMAS! Quote Link to comment Share on other sites More sharing options...
Ain't Nobody Here Posted May 30, 2011 Share Posted May 30, 2011 I'd never ever heard of BODMAS till I had to go with a child to a maths class - makes me wonder how we managed back in the day . Quote Link to comment Share on other sites More sharing options...
