### What do you say?

1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1 x 0 =

1. place your answer in the poll Mr Easy Peasy.. and then if you wish you can tell me what you chose.. or not.

2. I have done!

3. Anything multiplied by zero is zero!

5. Dave... you sure??

6. Yep. Too late now isn't it, I pressed the vote button LOL

7. Yep, just done it in my head again and I'm 100% sure.

8. I've just placed my answer.. it would appear that I dont concur with you or Paul...

9. if 1x0 is written as (1x0), the answer is 14. As currently written, the answer is 0.

1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1 x 0 = 0

1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+(1 x 0) = 14

10. Howdy .. have not seen you for a long time.

I understand your reasoning.. but there is something you are overlooking

11. there only seems to be 2 possible answers.

12. zero
no matter how many pluses, its still multiply by nothing...

13. 1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1 x 0 = 14

using the rules of BODMAS

1 x 0 = 0 +1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 -1

because...

There are no brackets, there are no Powers, there are no division, the Multiplication is worked out before the Addition and Subtraction.

14. I don't even know what the hell this is.

15. howdy, thanks for coming over. I love things like this. My kids and I used to often do things like this on long car trips.

16. If it had been written (1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1) 0 = then you would be correct Lyn

17. teasers.... simultaneously frustrating yet fascinating.... challenging yet compelling.....

and yes, i'm only talking brain....

no, i'm not...

18. Hands up who clicked on 16 and 14 then???

19. my math says if I drive 14 miles and multiply by 0...I can’t get back home....or get it off my odometer

20. lol Dave.. I think someone was hedging their bets and clicked on all four answers.

21. i dont know where the 14 even comes from lol

22. am i the only one who can count to 17..or the only one who is stoopid...

23. ummm, heatherbean... could be wrong but i'm thinking you're not seeing the minus sign about 3/4's of the way into the deal? then there's also the x 0 aspect, which is what's seemingly fooled folks...

meanwhile, i'm still wondering how glenn feels about angielina being suuuuuuuch a tease,,,,

24. ohh...puts on glasses

25. ...so, Heather.... do you understand that its the order of sequence as to what answer you receive.

we do the multiplication aspect first which is 1 x 0 = 0
then we do all the Addition which is 15
then we do the subtraction -1 from 15.

26. that pescy - sign is rather difficult to see

27. Sign, what sign? ;)

28. Just looked at it again. Saw the minus sign this time.

And the answer is still Zero.

29. Paul, it cant equate to 0. When working through the equation the functions must be worked according to rhe laws of BODMAS

30. P... P... P... Pythagoras told me :D

31. angielina, unless i missed it, twice you've mentioned bodmas without saying what it is... what the letters stand for.....

so whaaaaatisit? b-eautiful o-oohlala d-elightful m-athematicians a-ussie s-tylin?

or does the b stand for bondage? if so, i didn't know aussie mathematicians were so kinkaaaaay...

32. from what I know, ANY NUMBER THAT IS MULTIPLIED BY ZERO WILL EQUAL 0

33. I mentioned what it was in an earlier comment David but It wasnt set out step by step so the best way I can explain BODMAS

BODMAS is the sequence of operations when determining a mathematical equation.

Each letter stands for an operation.
The letters are listed in order of operations as they are applied.

This means that to work out a sum we do not begin at the start (left side) and work through to the end of the line (right side).
We work through the sum using the sequence of operations.

In their order, the sequence of operations is..

B=Brackets
O=Of powers
D=Division
M=Multiplication
S=Subtraction

so work through this particular sum, when applying the sequence of operations it will give you the answer 14.

even though the sum we are working out is written as this line...
1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1 x 0 = 14
this is not the order of sequence that we would apply to bring us to the answer.

we would instead place the 1x 0 as the first part of the sum to be worked out.. now you could write the sum as..
0 +1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1
The next order of sequence is Addition.. so add all the +1's
0 + 15 -1 = 14
The next order of sequence is Subtraction.. so subtract all - 1's
0 + 15 - 1 = 14

34. very true Annette but if you look at my explanation to David above you will see that I am not adding all the numbers before multiplying.

Instead I am multiplying 1 by 0.. which will be 0. then that leaves all the other digits infront to be dealt with in the correct sequence of processes.

35. If you use spreadsheets and are setting up formulas you will see these rules being applied.
