100x6=600 600x3=900 900+50=950 just 2 out

The point is that a good mathematician would not have to bother working out 318*75. It should be obvious that multiplying by 75, subtracting 50 and dividing by 25 will give you an answer 2 less that if you had just multiplied by 3.

They should have made the other guy do his 953 after him whilst the audience spat on him.

Guest: I hate the guest below (454 days ago)

Yeah we can all get 950 you twat! 950= Wrong you muppet

Guest (568 days ago)

No no no 'me', its just as Nez put it. Its very simple that way, its just that its only simple when put as 318*(75.25)-(50/25). It was only complicated when he had to deal with only having one 25, but that's really just a rearrangement. The hardest part would have been reaching 318, after that it was by 3, that was why he didn't have a ready answer when he asked for 318 to be multiplied by 75. If he'd done it that way originally he would have already known what that was.

Oh definitely 'mmm Suzie Dent'. She is cheeky.

Guest: Pete Star (561 days ago)

He didn't really work it out in 30 seconds - he was still thinking about it when Whitely was waffling.

I can throw you a geordie

Guest: tom (572 days ago)

i got 950 in 2 secs

Guest (545 days ago)

or a geordie

Guest: Dobbo (572 days ago)

He did it the same way I did.

Guest: tuan (540 days ago)

someone throw me an abacus

Guest: Guest (572 days ago)

Nez, it might have seemed simple to your mind and your method would certainly work IF there were TWO 25's.

Guest (572 days ago)

Fuppin show off!

Guest: nubnub (563 days ago)

all your comments have made me like mathematics again. numbers are beautiful. :-) thanks

Guest: Princess Dianna (556 days ago)

You'd never see a black man doing that.

Guest: Nez (572 days ago)

Guest, there doesn't need to be two 25's, he simply calculates the following: (318*75 +50)/25.... this simplifies to what i mentioned, and should have been of no surprise to carol especially that this works out!

Guest: me (572 days ago)

its still impressive to be done like that in 30 secs. 318x75 is tricky and isnt simple arithmetic and he had to have had the idea it would work. it is amazing he got there in 30 secs

Guest: Nez (572 days ago)

Sorry that should have been (318*75 -50)/25.... which simplifies easily to 318*(75/25) -(50/25)

Guest: Nez (572 days ago)

That really isn't that amazing, all he did was divide 50 by 25 to get 2. 318 * 3 = 954.... 954 -2 = 952. Fairly straightforward really. The only thing that made it seem complicated was that he had to get the 3 by doing 75/25 and the 2 by doing 50/25. People shouldn't be that impressed by basic mental arithmatic..... especially not carol with her engineering degree!

Guest (572 days ago)

MMMmmmmm Suzie Dent!

ZOMG i had mouth open for 2 minutes @_@ WOW!

Guest: lawranceio = a bellend (453 days ago)

@ lawranceio. In what universe does 600x3=900? Bellend

Guest (572 days ago)

It just impressess me that he decided to solve it that when he knew he only had 30seconds to do it. Never mind all this maths talk though. Isn't carol hot in a school teacher kind of way? I'd like to solve her puzzle! ( that doesn't make sense)
