The last part (×50, ÷100) is actually just halving it. I think this lad knew his 25 times tables.

That was good. But anyone who understands it can see how he put it. He could have simply divided 100 by 50 & then divided 1626 by 2. The real amazing step for me was how he got fo 1626! BONKERS
His method for getting to 1626 is based on the fact that you can make 937.5 with the four large numbers: 75 x 50 x 25 / 100 = 937.5. Now, that looks like it's miles away from the target, but by distributing in the 10 first, he does the equivalent of 75 x 25 - 25 x 10 = 1625, and since he knows that he's going to be doing the equivalent of division by two (50 / 100 = 1 / 2) that it will turn into 937.5 - 125 = 812.5. Now he needs to add something that will be equal to 0.5 when it's divided by two. In other words, he needs a 1 - and he has a 1. So (75 x 25 + 1) x 50 / 100 = 813.
Very clever! He didn't need to multiply by 50 and divide by 100, but it makes it looks all the more impressive! :) ((75-10) x 25) + 1) / (100/50) Amazing work in 30 seconds :D
@@hughmcilveen2235 No he didn't. You can use the numbers you generate by doing operations, he literally did it in his explanation. So he had the choice to do 100/50=2, 1626/2=813.
he used a standard technique for 4 big numbers. by adjusting by small values the following: (25*75)/(100*50)=937.5 you can reach most high numbers alot easier than just using regular intuition, often making your answer more accurate. Nicely done!
@@chrismulhern82 I'm pretty sure he meant to type (100/50). In fact, the 937.5 rule can generally be stated as 75 x 50 x 25 / 100, so you don't have to just use 100 / 50 = 2 but can also use 100 / 25 = 4 and even 75 / 100. The last is the least useful since it only allows you to reach targets that are multiples of 3, but sometimes it's the only solution that works. For example, the problem 100, 75, 50, 25, 7, 5 --> 849 can only be solved in the following way: 50 - 5 = 45 45 x 25 = 1125 1125 + 7 = 1132 1132 x 75 = 84900 84900 / 100 = 849
The first part was, the 2nd part was just a long way of dividing by 2, by x100 and /50, which is possible by just doing 100/50 to get 2 and dividing the number by 2. Basically just showing off unnecessarily, but still impressive with limited numbers

It must be great to do maths that quickly in your mind. Sadly something i will never experience but wow. I can make a nice spag bol, have to settle for that!
If you think she didn't already know how he would finish it when he said multiply by 50, you've clearly not seen much of Carol Vorderman. She knows he's right, and that the next thing he is going to do is divide by 100 because she can already see the simple solution of 100/50=2, 1626/2 = 813. Therefore, (1626*50)/100 is also 813, it's the same operation as before just rearranged, that's how maths works. She knows that he is correct because if the final answer is 813 and all he has left is 100, so he's clearly going be dividing by it, so 1626*50 must be 81,300.
Well he didnt need to know what 1626 times 50 was, he simply needed to know 1626 was twice 813 which was the goal number. Thus is becuase timesing 1626 by 50 then dividing by 100 is equivalent to dividing 1626 by 2.
The way it is shown here makes it way more complicated than it really is. He could have divided 100 by 50 and gotten a 2 which he could have used to divide 1626 with.
I know right. 1626 x 50 is very easy to do in your head. Just do 1626 x 100 which is simple, just add two 0's. Then cut it in half. What is so hard lady?
I knew someone who worked on the floor of the show and know for a fact that she had longer to do this than the show would suggest. She took breaks sometimes. She was an engineer after all. Now, Rachel Riley however, is the real deal.
I’ve been at a cats does countdown and Rachel Riley was given time to work something out on the board and they cut back and filmed after the initial filming took place
Once he got to 1626 he knew all he had to do was divide by 2. He could get the 2 by 100/50 of course, but a fancier way is multiply by 50 then divide by 100. Knowing the result will be 813 you know the multiply by 50 will give the 81300. Very very clever chap to come up with that in 30 seconds, though of course it's a solid knowledge of his 25 x table.
He's on his way to winning that countdown teapot.

No they got her only because Carol quit (several years after this episode was shown). I've seen that Riley female fail far more times that Carol did.
If you think she didn't already know how he would finish it when he said multiply by 50, you've clearly not seen much of Carol Vorderman. She knows he's right, and that the next thing he is going to do is divide by 100 because she can already see the simple solution of 100/50=2, 1626/2 = 813. Therefore, (1626*50)/100 is also 813, it's the same operation as before just rearranged, that's how maths works. She knows that he is correct because if the final answer is 813 and all he has left is 100, so he's clearly going be dividing by it, so 1626*50 must be 81,300.
I got 211
LMAO 211 LIKES IM CRYING
@@namxxn yes crazy
That is some crazy mental arithmetic!
Countdown showboating love it
1:22 What a show-off! LMAO
Well he didnt need to know what 1626 times 50 was, he simply needed to know 1626 was twice 813 which was the goal number. Thus is becuase timesing 1626 by 50 then dividing by 100 is equivalent to dividing 1626 by 2.
@@yatoproductions163 1 times 50 is 50 and if you divided 50 by 100 it's 0.05 which is the same as dividing 1 by 2
The way it is shown here makes it way more complicated than it really is. He could have divided 100 by 50 and gotten a 2 which he could have used to divide 1626 with.
He knew that of course. In modern lingo, it's what they call a flex, i.e. showing off.
Amazing
Very good
By my calculation, Carol would fucking get it.
Carol wasn't good enough for huge numbers. Look at the 952 video, she's overwhelmed. Rachel would have had more of a shot
I'm taking your word for it .. proves she isnt such a maths expert
I know right. 1626 x 50 is very easy to do in your head. Just do 1626 x 100 which is simple, just add two 0's. Then cut it in half. What is so hard lady?
BRILLIANCE
nice amazing
I paused this for 5 mins, still nowhere near, pretty impressive
I knew someone who worked on the floor of the show and know for a fact that she had longer to do this than the show would suggest. She took breaks sometimes. She was an engineer after all. Now, Rachel Riley however, is the real deal.
Alex Tomlins except carol is a private pilot and isn’t a pro Zionist pig.
@@DerbJd We have our eye on you.
I’ve been at a cats does countdown and Rachel Riley was given time to work something out on the board and they cut back and filmed after the initial filming took place
Great presenters RIP Richard
Great!
"Carol you're literally laughing at numbers."
I thought that I had done quite well in attaining 811
100+50=150
150/25=6
75+6=81
81×10=810
810+1=811
That was dope
Well done sir
Once he got to 1626 he knew all he had to do was divide by 2. He could get the 2 by 100/50 of course, but a fancier way is multiply by 50 then divide by 100.
Knowing the result will be 813 you know the multiply by 50 will give the 81300.
Very very clever chap to come up with that in 30 seconds, though of course it's a solid knowledge of his 25 x table.
I had gotten a decent 814
(75+1) * 10 + 50 + (100/25)
Same!
Brilliant
