the rules and the rules are you're

allowed to add numbers together you're

allowed to subtract numbers you're

allowed to multiply numbers and you're

allowed to divide numbers you're allowed

to have powers but i'm actually not

using those because when you're writing

a program to do it they explode you get

these ridiculously big values and it's

just easier to not bother but they are

allowed I'm just not going to use them

and you're allowed to put brackets in to

choose the order so I'm going to put

some brackets there to symbolize that

and you're allowed to just bunch the

numbers together so if you look here

concatenation there you go well done

there you guys think that earlier today

they were you going to have a

concatenation theme today in fact you

could take these two videos that

involved concatenation and just play

them one after the other and so you

didn't bat an eye when three four five

six you like what hang on you didn't

think well what's the mathematical

operation you've done there to put them

in order you're just perfectly happy

that of course three four five six can

be there and so concatenations a strange

one there's no agreed symbol for

concatenation some people use two lines

some people use a plus in a circle some

people use like little dashes or dots

are all sorts of things i'm going to use

i tend to use the two lines right in to

be complete I probably should have put

in this picture if we go back to the

past to fix previous errors if I sing

more star I would have put three

concatenate for concatenate five

concatenate six and down here actually

done for concatenate three right you

know to be more fun so that is

concatenation is clearly allowed if we

just for some reason we never bother

spelling it up so what I'm going to do

is here's my almost but not good enough

attempt so gonna be a park of square

this is really cool right so you start

with 12 so one concatenate two to 12

then x 3 x 4 divide that by five

multiply it by six multiply it by seven

add on eight put that whole thing in

brackets and then multiply that

by nine okay so what does this equal

let's check that and we're close 10 9 58

mark with exactly if it equal 10 9 58 we

are on so here we go so one can catenate

to that's 12 x 3 x 4 / 5 x 6 x 7

equals okay so the whole thing there

plus 8 equals 1217 point 6 times 9

equals ten thousand nine hundred 58.4

that's that's not bad ten thousand nine

hundred if you say classic parker square

where you're in so much trouble Brady

laughs come on that's not bad right

that's as close as I can get within the

rules as initially I understood them man

what we'll do you think I'm not going

back a square on the screen runner okay

like a hashtag thanks for the quick a

day is unnecessary right okay anyway so

as long as you try to sell the t-shirt

again but do you know how many people

shop to my shows wearing Parker Square t

shirts unbelievable honor right anyway

so what's interesting about the

concatenation thing is it's never

explicitly stated to be able to look at

the start of the paper he talks a lot

about he loves plus product potentiation

two powers and brackets loves those he

will concede you can add in- and

division which you like the SEC they're

not as good as plus and multiplication

or products but they're okay and they're

allowed it he never explicitly says

concatenation all he does is in here he

goes you can add a and B multiplied a

and B powers of a and B oh and of course

AMV forming a number so all the ones in

here a lot of them do use concatenation

right from the beginning it's never

assumed you can't do that but it's never

used as a step during the calculation

it's only used in a setup of the numbers

that you then apply the other operations

to and I like that's a bit arbitrary it

should be a fully-fledged function if

you go include it you've got to include

it and so I found one x two concatenated

with three plus in brackets

four times 5 times 6 and then that so 4

times 5 just you know we're going with

this that's going to be 20 x 6 is 120 but

then 120 is concatenated with seven so

now you do the calculation first and

then you concatenate with another digit

then you add on an eight and that whole

thing you multiply by nine shall we

check it let's just do this simplify it

to their equals k 1 x 23 that's just 23

i think we're all quite happy with that

plus in brackets that's going to be 4

times 5 is 20 times 6 is 120 concatenate

with seven and then we're going to add

on 8 and then we're going to multiply

that 59 so now we've got 23 plus 12 if I

want to do this all at once actually you

know I'll do that step there is a

concatenation plus 8 and then that

there's x 9 okay so let's let's so we

checked into the calculator now that

feels like it's obvious enough that we

can we can drive this home 1207 plus 8

equals unsurprisingly 1215 x 9 equals

that plus the 23 at the top equals ten

thousand nine hundred and fifty-eight

there it is so we have filled the gap

because the gap was only there because

people weren't taking concatenations

seriously and I I've taken it seriously

I filled the gap and I'm going to send

it in I'm gonna I'm gonna be like I

think I thought the gap it is it is now

available let me give you that really

that's the only reason I found this by

the way is because I wasn't afraid to

try something where the odds are i was

going to fail miserably and i said i

think that is the morale of the Parker

square right you give it a go even

though it's probably not going to work

and you embrace it you own it when it

doesn't work every now and then it does

work out for you

times that base have we worked out the

length or something well you use a log

right so is log base whatever the base is

of your next digit
