Here's A Nice Maths Oddity......

196-182x0.5=7!!

Is that correct?

[ToraToraTora]

prudie, sorry tetration is not to do with this question just wondered if you'd heard of it.

I thought TTT claims to have a job? If so it can't be very onerous.

[Prudie]

No I haven't TTT and I'm reading through it now.

Believe it or not I had heard of tetration, although I only remembered when I opened the link. Probably because of our fascination with huge "meaningful" numbers like Graham's number

Tora did it again & yes it is 105. My mistake I was a digit out.

[ToraToraTora]

NP shaz, I think you were doing 7x5x3+1

[Old_Geezer]

Seen that one.

!! isn't something any individual, apart from maths professionals, are going to know. As such it ain't a reasonable question to ask most people.

[elliemay1]

I thought it was quite interesting

[ToraToraTora]

that's why it's in science OG. If it's too heavy for you then feel free to absquatulate.

As somebody who definitely isn't a maths professional, I knew about the double factorial, but I was too sleepy to notice it just now :P

I can't see a harm in introducing such topics in a semi-serious way. The quirky maths stuff out there beyond what we learn in the classroom can be fun :)
