Background:
Countdown is the channel’s longest running show and the first show ever broadcast on Channel 4 when it launched 40 years ago, in November 1982. The original version of Channel 4's Countdown is the French television programme « Des chiffres et des lettres » (literally "numbers and letters"), where the numbers round is referred to as « Le compte est bon » ("the total is right"). DCDL debuted in 1965 as « Le mot le plus long » using letters only, and reached its present format in 1972. This year marks the shows 50th anniversary.
Spin-off:
"8 Out of 10 Cats does Countdown" is hosted by Jimmy Carr, with Rachel Riley and Susie Dent assuming their Countdown roles. The formation of the crossover with "8 Out if 10 Cats" began as a series of specials, the first of which was broadcast on 2 January 2012, when Channel 4 orchestrated a special "mash-up night", merging two shows to form a special edition of the pair, as part of its 30th-anniversary celebrations ten years ago.
Btw, I missed Richard Whiteley very much when I watched his first countdown appearance in today show's archive. He was very funny.
For the first round, it is easy to be noticed that 776 = 800 - 24 = 8 x 97. Therefore, the easy way for the first round is:
100 - 3 = 97
97 x 8 = 776
For the second round, I get the same as Rachel's solution as it is easy to get 73 and 10.
For the third round, a one-away solution (I guess it is the one in Rachel's mind) is:
100 + 3 = 103
10 - 1 = 9
103 x 9 = 927
927 - 6 = 921
For the final round, it is also an easy round. Another solution is:
100 + 25 = 125
125 x 2 = 250
8 / 8 = 1
3 - 1 = 2
250 + 2 = 252
730
75 - 2 = 73
100/25 = 4
4 + 4 + 2 = 10
73 x 10 = 730
776:
8 * 100 = 800
3 - 2 = 1
800 - 25 + 1 = 776
100 - 3 = 97
97 * 8 = 776
75 - 3 = 72
72 * 8 = 576
2 * 100 = 200
576 + 200 = 776
Hope they get Paul Coia to do it as he was the first voice on C4 in 1982 - well,continuity announcer!
Paul Coia, my goodness that’s a blast from the past. I was already getting nostalgic seeing Floella.
776
8 x 100 = 800
800 - 25 = 775
3 - 2 = 1
775 + 1 = 776
Countdown's first episode was on 2nd November 1982, the same day as Channel 4 launched
The actual day of the anniversary, as you've pointed out, is of course tomorrow. In case you're referring to the date in the title (31 October 2022) though, Channel 4 will have a total of 20 such anniversary episodes over the next four weeks; during their anniversary month.
3rd impossible 921 best
75/25 = 3 + 6 = 8
100 - 8 = 92
92 x 10 = 920
920 + 1 = 921
Woah, the clock is showing the 40!
Yes, it's probably going to throw off people thinking that they have 40 seconds.
@@pjabrony8280 it’s the 40th anniversary of Channel 4.
I can't believe they didn't just do this:
100 - 3 = 97
97 x 8 = 776
If you want to use all the numbers, you can do this:
100 x 2 = 200
200 + 75 = 275
275 - 8 = 267
267 x 3 = 801
801 - 25 = 776
However, the more complex solution is pointless since it's still based on the same idea as (100 - 3) x 8.
This second round is also easy, but there's only one solution.
The third round is impossible, but there's an easy way to one away using Lewis' starting point:
10 - 1 = 9
100 - 6 = 94
94 x 9 = 846
846 + 75 = 921
The other way I saw was:
100 - 1 = 99
99 x 10 = 990
990 + 6 = 996
996 - 75 = 921
The final round was also easy:
100 - 8 - 8 = 84
84 x 3 = 252
And a more interesting solution using all the numbers is:
25 + 3 = 28
28 - 8 = 20
100 x 20 = 2000
2000 / 8 = 250
250 + 2 = 252
I got this idea from the four-large technique of multiplying 100 x 50 and dividing by 8 for 625.
Ah yes, the 94 times tables, of course
Has nothing to do with the 94x table actually. You got 921 with a digit sum of 9+2+1=12 and you subtract 75 with a digit sum of 7+5=12 from it, so your answer (i.e., 846) will be divisible by 9 and 846/9=94. Then you just have to figure out how to get the 94; however, it's an intermediate result and there's no need to know the 94x table to make use of it.
For the 921 - in which I got stuck before Rachel said it was impossible - I did
10-1 = 9
100 + 75/25 = 103
103*9 = 927
927 - 6 = 921
@@kingofrunescapepking Actually, I got it from the 9 times tables. Specifically, 9 x 6, and being able to tell that the difference between 75 and 54 is 21. So, if you subtract 6 from 100 before multiplying by 9, you get a number that when you add 75 to it becomes 921.

When did Colin go?
Check the pinned post. Channel 4 40th anniversary. Rotating hosts for the month.
730=(75-3)×(100/25+4+2)
Anyone know the rule on decimals?
For 922 I got
100x10=1000
1000-75=925
25/6= 4.16
925-4.16+1=921.84
The rule is: You are not allowed decimals.
If you just take the 1 off the 25 before dividing by 6 you get to that 921 which is as close as possible for that one.
@@shadowstemple9863 Thank you.
Or 100-1=99
99×10=990
990-75=915
915+6=921
As noted, every step of the solution has to be a whole number. However, you can do (25 - 1) / 6 to get 4 and get 1 away using your method, which is the best solution possible under the rules.

She's got a personality which was better than Anne
@@alexashton6501 it's how shes coming across
Floella Benjamin is a legend and she's got presenting credentials going back over 40 years.
