Looks like some of that common core bullshift! :roll:

42

When I went to school we used BODMAS, but I don't think that gets used anymore.

1 Horse = 10
2 Horseshoes = 4
2 boots = 2

1 boot + ( 1 Horse x 1 Horseshoe) = 21

Uh, hold on there, Kimosabe! =; [-X [-( That would be boots (2) + ( horse (10) x horseshoes (4)), which is to say, 2+(10x4), and if I'm not mistaken :-k, that tallies up to 42. :thumbsup:

Yeh thats what I thought Halgar, but must be the way the brain works....

Horse = 10
Horse Shoe = 2
Boot = 1

In the first 3 equations there are two horse shoes and two boots. In the actual math problem there is only one horse shoe and one boot.

So, 1+10x2= 21

Ah, you would be right about that! All the more reason I hate these types of misleading questions that take advantage of generalities the brain makes. The same thing applies when asked a this question, the eyes see, but the brain is the one doing the reading, so most people get it wrong.

When you read, do you actually look at every letter to decipher a word, or do you glance at the collection of letters and remember what that collection represents? That is why you can jumble a word, but as long as you put the first and last letters in place, the brain can almost instantly "see" it correctly. This is also why when you are proof-reading your own work, you "read" what you think you wrote, instead of what is actually written.

I have to say with the math question i was focusing on multiplying before adding, didn't actually notice that there was only one shoe and one boot. My brain is so dumb, it gets tricked at times, luckily I keep an eye on it. :wink:

the way the equation is presented gives an answer of 22, to get 21 it would horse x shoe + boot

It's 21.., because you multiply before you add.... so it is horse x shoe + boot.

oh yea, your right, I remember that now, my last job of 10 years had me having to do addition before multiplication, so that threw me.

I do recall a math problem in a book way back in school, the book was for students 2 yrs above me I believe. My math teacher handed it to me after I'd mentioned that the math we were doing in class was easy, problem was, the teacher gave me no instructions, and couldn't provide me any information on how to work out the problems as it was beyond her training at the time. I have never forgotten about the equation which is:

19532
x54368
x73225
x42667
x32881
-------

Admittedly those are not the actual numbers of the equation, but it is the exact same format, and even tho I've never forgotten the format, it has never bugged me enough to look up how to solve it, plus I've never needed to solve an equation in that same format since that book.
