1010 BIN = 10

9? PaulB2005, 9? Come on, I know you are better than that.

Start at the beginning and double the number, then add on the next digit, double this number again and add on the next digit etc.

So 2 x 1 = 2 + 0 = 2
2 x 2 = 4 + 1 = 5
2 x 5 = 10 + 0 = 10.

1001 BIN = 9

2 x 1 = 2 + 0 = 2
2 x 2 = 4 + 0 = 4
2 x 4 = 8 + 1 = 9

Much easier and quicker than the way taught. :D

There's an easier way of doing it the other way round too.

E.g. 365 to Binary.

Write the number to the right of the page. Halve the number and write down the result to the left of it. Ignore any fractions.

In this example halve of 365 = 182.5 ignore the .5 = 182.
Halve the 182 = 91.
Halve the 91 = 45.5. Ignore the .5 = 45 etc.

1, 2, 5, 11, 22, 45, 91, 182, 365

Start from the left and write a 1 for odd numbers and a 0 for even.

1 0 1 1 0 1 1 0 1

See, and I have only 50% of Oldboys brainpower. :P
(Half his looks and money too, no doubt). Thumbs Up

There's only 1 type of people in MY world - He doesn't understand binary (although I'll admit I DID learn enough to eventually get the 10 people thing). It didn't exist when I got my GCE O level in Maths (and if it had done, I wouldn't have understood it - when my GCE result was promulgated, my maths mistress was furiously trying to find out how I'd cheated).

My upstairs light comes on when I click the thingy and sometimes it goes off when I click it. - doesn't matter which one of them either, whichever I'm nearest does whichever I want it to - if I'm upstairs and want to switch it off I can, but if I'm downstairs I can switch it off too. That's what light switches do.

My grandson several years ago accompanied me to the toilet and observed me carefully flush it. I asked him why the bubbles were white when the water was blue (thinking it would be an interesting point of discussion). He replied flatly "because that's the colour bubbles are, grandad." Light switches are just like that (a great improvement on the gas lights we had in our house when I were a lad in 't factory with threepence change).

Can I bring the thread down by pointing out that the 1010 thing wouldn't actually work.

At risk of spoiling the humour in PaulB2005's sig by having to explain it to 'those who don't', as 1010 equals 10 ( decimal ) not 10 ( binary ) which equals 2 ( decimal ) there is a requirement for those who actually do 'get binary' to forget it briefly. Where's the fun in that Question

Otherwise, we could go 'there are 1111110010 types etc..' and then 'there are 11000101111010 types' and so on and so on and zzzzzzzzzzzzzz.....

I may never laugh at this quirky little joke again. Thanks. Sad
