2×itself×itself=16

Innit?

Drubk. Happy chrisas

No

By similar logic triplets is 4 kids.

2xitselfxitself is just a bad way of writing 2x2x2.

To get 16 you'd have to do something like f(f(2)) where f(x) = x^2. Which is of course just writing x^4 in a recursive fashion.

2 x 22 = 8

Or is there a Christmas maths joke none of us is getting?

If itself = √8 then the answer is correct.

Two cubes is a hexahedron.

Here’s what you do:

Move the cursor to the number 16 on the LL3 scale. Then, draw the number 3 on the C scale (to find the third, or cube, root) under the cursor.



now, move the cursor to the index of the C scale and read the solution on the LL2 scale:



Around 2.52.

Actually, even ONE cube is a hexahedron - a regular one.

Yes, that's correct. But not funny.

Maybe not, but then I was not aware that humour was obligatory.
Please also relay my apologies to Baldrick.
Thankyou.

Every time I start to think the Metatron is cool, I find out I underestimated him, and that he is way cooler than I realized.

A slide rule.

A fucking slide rule.

I thought I was the shit because I use triangles to build crap.

But a fucking slide rule? I'm still geekin' out about it.

Well, thanks. That’s as nice a compliment as I’ve ever got. It’s been my experience though, the group of people who share your assessment is small.

Those were screenshots of one of the slide rule apps I have on my iPad. I wish I knew how to make those apps, because it would be very cool if I could rewrite the app so one could select from different models and makes of slide rules.

I have about 25 of them in my collection, with a few duplicates. When I was actively collecting them, I got the duplicates of some models for my boys, so they could learn to use them, too.

Primus was using his to produce answers to his maths problems instead of learning how to manipulate exponents and radicals to solve problems with powers and roots. I couldn’t fault his ingenuity at all.

It occurs to me that he was likely the only 13 year old kid on the entire planet who was using a slide rule to cheat on his math problems.

Perhaps if we added parenthesis? The title of the thread belies this but maybe the original statement of the problem was a puzzle designed for someone to try to make the statement true in some way?

(2×itself)×itself=16

Edit: 'thread' was 'post'

'itself' = 2?

This problem shows exactly why the word, "itself" is not generally used in algebra!

Could it be that what the OP was trying to express is something like a recursion:

X(n+1) = X(n) * X(n) with X(0) = 2? You can get X(2) = 16 this way.

Naah. The language in the OP has no vocabulary, no syntax, and no grammar. What does that make it? Drubk!

It's Devish, a little known dialect of teangacha Gaelacha.
