Tricky Maths (But Fun)

[ONeill]

O'neill hasn't explained it right.

There are a number of combinations to get 72.

The sum of only two of the combinations give the same number. 2x6x6 and 3x3x8.

So, when yer boy still wasn't sure, it means it was one of those two combinations.

When yer boy said he had an eldest.

Well......

But 1, 8 and 9 would do the same job, and give a birthdate of 18?

And so would probably 10 other combinations. Yer man hesitated. A doubt. Them twins. Or were they?

Hardstation really schooling O'Neill tonight. Painful to watch.

Watch this space in, say, 3-4 years...'teachers get it handy' may see HS take a gentler approach....

[ONeill]

What do these numbers have in common?

4, 12, 30, 60, 102 and 108

[ONeill]

Excellent.

You're an awful balax.

OK, I missed a few out to avoid some Googling the answer.

So, bearing in mind I missed a few out in that series, what is next after 108?

Unable to do indices here but I'll try. The brackets are only to tell you the power of the x.

4x(to the power of -3) divided by 2x(to the power of -5)

All divided by

2x(to the power of 2)

Go.....

4squared is 16

3-1=2

16 +2=18

18+6=24

Can you square in Countdown? If so, my bad, take another 5 mins.

Add, subtract, multiply or divide only.

Booooo. Hisssss.

By the way, how were you able to square the 4? There wasn't even a 2 ffs.

Are you serious?

138

Yes.

2?

No but how'd you get there?

Really? As you're close but strange you got that number.

misread 2x(to the power of 2) as to the power of -2

1

Fcuk this.

0.125x0.03125 =

Ah ffs. Wasn't using the 0.03. Was going 0.3

Erm, I think so....
I mean, I could see it if you said 1 to the 3 is 1. Multilply that by 4 to get 4. 4 by 6 = 24.

But where'd you get the square (2) from?

The '2' is simply the symbol for square in the same way that '-' is the symbol for minus.

6 divided by (1-3 divided by 4)

Or

6/0.25

Surely that is correct - 3/4 = 0.75

1 - 0.75 = 0.25

6/0.25 = 24
