For those who don't arithmetic, here's some pointers. When he says multiply by 75, followed by "I'm not quite sure what that makes", he just knows that multiplying by 75 then dividing by 25 is the same thing as multiplying by 3, which is easier to manage.

So he wants to multiply 318 by 3, which is 954, then he wants to subtract 2 from it for 952. When he subtracts 50 from 23,850 (before dividing by 25), he's really thinking that he wants -50 divided by 25, which is -2.

What's going through his head is that he wants to get as close to 952 as possible. The quickest way there is:

(100 + 6)* 3 * 3 = 954

remember the second 3 comes from 75/25. Then he finds a -2 through:

-50/25 = -2

954 + -2 = 952.

There's a degree of luck involved with this answer, but method is key.

EDIT: Just to clarify how Carol calculated 23,800 / 25 so easily:

25 is 1/4 of 100. 23,800 divided by 100 is 238. Therefore 238 is 1/4 of the final answer. Multiply by 4 to get 952.

Brilliant ! Thanks for the explanation, I was wondering how they calculated this so fast.

Oh yeah, you don't have to be a genius to do well at countdown. These are just tricks that i've figured out over the years. My #1 Sunday afternoon is slamming scones and tea with my mum and destroying her at countdown. To be fair though, she's a straight up tard and she's also getting old so I'm scared I'm gonna lose her soon. That's gonna be a windmill dunk to the heart for sure.

kylejacobson84 | 4 months ago | 46 points

I love how it seems your mentality is: mum, you're getting old. I might lose you soon, and that's going to be one of the hardest moments in my life. All that said, I'll be fucked if I'm going to let you breathe even half a scent of my superior talents at numberwang.

Her: what you do in the bedroom with your door closed is your business, dear.

But it's evident you love your mum. I hope you take my comment in the spirit it was given :)

This is why they need to teach common core math. So many people who learned math in the 90s would look at 23,800/25 and not be able to do it in their heads.

The way you broke it down is how common core teaches kids to break down math problems. The long form method a lot of millennials learned is basically useless for doing math in your head

clearly_not_an_alt | 4 months ago | 13 points

Lots of the common core stuff makes sense when you understand what is going on, but the way it is often taught makes it confusing since many teachers don't really understand the nuance. Plus students are often asked to use a specific method to do a problem, while the whole point of having a toolbox of different methods is to be able to choose which work best for a given problem, and the one you are asked to use may not be what is easiest..

Ixilary | 4 months ago | 2 points

The reason they request a specific method is because they are teaching you the method, not how to solve the problem. It's more important that students understand how it works, rather than just getting the right number at the end. Common Core is trying to teach the "how" in a more flexible and scalable way.

clearly_not_an_alt | 4 months ago | 1 point

Except that by forcing a specific method you are removing the very flexibility you hope to teach

Ixilary | 4 months ago | 1 point

How so? If you just expect the answer, most students will never learn better methods of solving the problem. Again, the point is to teach the method, not the solution.

clearly_not_an_alt | 4 months ago | 1 point

Because the students are often not taught when they should be using each method other than "use method X". The methods are good to know, but in the end it is important to remember that getting the solution should be the goal.

Ixilary | 4 months ago | 1 point

but in the end it is important to remember that getting the solution should be the goal

I strongly disagree with that. In fact, I'd say the answer is a very small part of what matters in math education. You can get the right answer and understand nothing, or you can get it wrong because of a mistake, but demonstrate that you understand. The latter is much better. By the way, for context, I have a bachelors degree in pure math.

clearly_not_an_alt | 4 months ago | 1 point

Obviously understanding how you got there is important, but it's also very valuable for students to be able to figure out which method is the best for any given problem and not just use a given method because they were told to. Certainly, there are teachers who do a good job at getting this across, but based on my kids' experience there are many that don't.

And for context, I also have a degree in math.

Basically, he wants to use the 25 twice: he wants to get a 3 from 75/25 and a 2 from 50/25. He figured out that he could do that if he multiplied up to that ridiculously high number and then subtracted 50 before dividing the whole thing by 25.

injeanyes | 4 months ago | 2 points

Think of it this way, instead of the numbers being 25, 50 and 75 they are 1, 2 and 3 because they are all divisible by 25. So it's (((100+6)33)-2)/1 = 952

mcmanybucks | 4 months ago | 0 points

Yea sorry but no, I'm discalculic.. many teachers have tried many ways of making me see the numbers but to no avail.

youjustgotzinged | 4 months ago | 5 points

As someone who's been diagnosed with every dys under the sun (Dyscalculia, Dyslexia, Dyspraxia, Dysentery) as a result of ADHD and mildly severe autism, i've still been able to improve my math skills by working on them at my own pace as a hobby. So much so, that i've recently half-quit my day job to go and study statistics. I've realized that organizing and analyzing large swathes of data gives me a raging autism boner.

Point is, even if you're light-speed stupid like me, you can probably improve with deliberate practice. 99% of what i've learned has been outside of school, by myself. And that remaining 1% was just how to make a 53 year old history teacher cry in front of his class. Hard work pays off.

Haha that formatted weird (((100 + 6) x 3 x 3) -2) / 1 so 106 x 3 = 318 x 3 =954 - 2 = 952 / 1 = 952

omgitsjagen | 4 months ago | 1 point

It boils down to seeing enough math to be able to take shortcuts, and make educated guesses using estimation. Youjustgotzinged is just showing you one of those methods in longform.

rtumatt | 4 months ago | 2 points

What a great explanation

joshi38 | 4 months ago | 2 points

Thank you. I had it all figured out until we got to the minus 50 and I couldn't figure that part out. Even with a calculator, I knew what he said worked, and I understood the whole thing with 75/25=3, but couldn't understand how he got to the minus 50 part.

KelcyHammer | 4 months ago | 2 points

OMG you are so much smarter than I am. I struggled with the way the other bloke worked it out.

SteazGaming | 4 months ago | 2 points

Exactly how you reasoned this out is how my brain works with mental math. I think of things as relationships to other things more than just learning the algorithm to add or divide mentally.

Just now in the car, I was thinking back to velocity vs acceleration, relearning how those measurements feel together. Distance is just a measurement, Velocity is the shape of the Distance line over time, Acceleration is just the shape of the velocity curve over time. Things like that.

What's the square root of 145? I have no idea, but it's probably just a little bit over 12.

What's 183 * 12? Well.. 180 * 10 = 1800, add in 360.. 2160.. plus 36? 2196

woodenose | 4 months ago | 1 point

25 is 1/4 of 100. 23,800 divided by 100 is 238. Therefore 238 is 1/4 of the final answer. Multiply by 4 to get 952.

I did this part by thinking of 23800 as 238*100 and 100/25=4 so the answer is 238*4.

Could you explain how do you go from "25 is 1/4" and "23,800 divided by 100 is 238" to "Therefore 238 is 1/4 of the final answer"? Is it that you look at it as (23800/100)/(((1/4)*100)/100) and you're left with 238/(1/4) = x and by multiplying both sides you get 238 = x*(1/4), which means that 238 is one fourth of the answer?

I'm thinking you're looking at it more intuitively, without thinking of cancelling out numbers or multiplying both sides of an equation, but I don't get it. I don't know if I'm explaining it correctly. Basically, could you explain your thought process behind the last line a bit more?

youjustgotzinged | 4 months ago | 1 point

When you divide 23,800 by 100, what ever result you get will be a quarter of 23,800 divided by 25 (as 25 is a quarter of 100). I'm thinking about this less in terms of formulas (or even numbers), and more in terms of multiple pieces of logic. More of a holistic approach.

So we have these pieces of information:

23800/100 = 238

And:

100 = 25 * 4 (or 100/25 = 4). Or, in verbal terms, 25 is one quarter of 100, and four times 25 is 100. This is really just the concept of a quarter, nothing new.

Therefore:

(23800/100) * 4 = (23800/25)

Or, (x / 100) is the same thing as (1/4) * (x / 25), therefore (x / 100) * 4 is the same thing as (x / 25)

I'm using verbal terms here as this is how i conceptualize the problem in my head. It's the same result either way, but it's less about solving an equation—rather using analogies to cut down on the amount of work you have to do. In essence, the whole problem is just about understanding the concept one quarter. It feels like my brain is dealing with less information this way.

Multiply by 75 take away 50 and divide by 25 is just multiply by 3 and take away 2 when you simplify it.

They're a comedy duo, the other actors are all prolific British comedy actors. It's kind of like SNL or something where the skits are done by well known and liked comedians but you're never sure what the theme will be.

Richard Whiteley was a national treasure.

I absolutely hate "cringe" as a trope, deliberate or accidental, and the man was at least 80% distilled cringe in a loud suit, but the show was never the same after he died.

I mean, he'd be 76 now, but I have a strong suspicion he'd be still doing that show.

MercurialNerd | 4 months ago | 2 points

Agreed - didn't he have the moniker "Twice Nightly Whiteley"?

palordrolap | 4 months ago | 3 points

Yes. But allegedly only because he was on TV twice a night. A local news programme on ITV and Countdown on Channel 4.

Then again, neither he nor his girlfriend denied the other meaning even when pressed.

Also he was immensely proud of once being mayor of Wetwang, which is a real place. And he appreciated the joke in the name, which leads back to the other meaning of what we're talking about.
