Countdown Game Show - Number Rounds (9 July 2024)

[@RQLexi]

So from the contestants, this really was an instance of 404 not found

[@JimmySands-pd7xt]

I rarely get the conundrum but got this one almost straight away; amazed that no one got it!

[@shoredude2]

I rarely get the conundrum. I've very happy that I got it when nobody else did.

1. (75+9-4)x3+7=247
2. (100+1)x(6+7-9)=404
3. 2x9x(5+6)=198
4. (50-1)x(4x5-9+6)=833

247:
75 x 4 = 300
7 x 9 = 63 - 10 = 53
300 - 53 = 247
198:
6 + 5 = 11
x 2 = 22
x 9 = 198

833:
50 * 4 = 200
200 + 6 = 206
5 - 1 = 4
206 * 4 = 824
824 + 9 = 833
50 - 1 = 49
5 * 4 = 20
9 - 6 = 3
20 - 3 = 17
49 * 17 = 833
50 - 1 = 49
6 * 5 = 30
30 - 9 - 4 = 17
49 * 17 = 833

247:
75 * 10 / 3 = 250
7 - 4 = 3
250 - 3 = 247
75 + 4 = 79
79 * 3 = 237
237 + 10 = 247
All small:
9 - 3 = 6
10 * 6 * 4 = 240
240 + 7 = 247

[@medusa_404]

198:
100 - 1 = 99
99 * 2 = 198
9 * 5 = 45
45 + 1 = 46
46 * 2 = 92
100 + 92 + 6 = 198
5 * 2 = 10
100 + 10 = 110
110 * 9 = 990
6 - 1 = 5
990 / 5 = 198

247=3×(75+7)+10-9

[@medusa_404]

404:
75 + 25 + 1 = 101
7 + 6 - 9 = 4
101 * 4 = 404
75 - 25 = 50
50 * 7 = 350
9 * 6 = 54
350 + 54 = 404
9 * 7 * 6 = 378
378 + 25 + 1 = 404

Damnit, I was half way through Rachel's 833 solution, but then abandoned it thinking that 119 is a prime number. Was shooting for 7 x (7 × 17) instead of (7 x 7) x 17

[@Zarren_Redacted]

For 833
5-1= 4
4x50=200
200+6= 206
206x4 = 824
824+9 = 833

[@quizmaster85]

First one:
75 ÷ 3 = 25
25 × 10 = 250
7 - 4 = 3
250 - 3 = *_247_*

[@einSteppenwolf]

198=2×9×(6+5)

[@Jothamvvw]

I did the 404 almost the same as Rachel, I did 6-(9-7) instead of 6+7-9 (I know that's numerically the same)

[@stismail]

404: 75 - 9 = 66 × 6 = 396 + 7 + 1 = 404

[@helentowse4990]

75-25 = 50 x7 = 350 + (6x9) = 404

404=(7+6-9)×(75+25+1)

[@TeamPaul17]

For 404, I found a solution that I was certain Rachel would offer up, given how similar it was to James':
75 - 9 = 66
66 * 6 = 396
396 + 7 + 1 = 404

[@5114355]

75-9=66
66*6=396
396+7+1=404

[@quizmaster85]

No wonder the studio drew a blank on the Conundrum - there's no audience.
