@C4Countdown @Channel4 @thedebbiemcgee @ColinMurray @susie_dent @RachelRileyRR Sorry, missed a bracket .. ((75-8) x 7) - 8

@C4Countdown @Channel4 @thedebbiemcgee @ColinMurray @susie_dent @RachelRileyRR ((75-8) x 7 - 8

@C4Countdown @Channel4 @ColinMurray @susie_dent @RachelRileyRR Missed yesterday's game, but the fan site gave this insane last numbers round 100,50,75,25, 10 and 5 with a target of 832.
I'd been trying to get 104 x 9, 52 x 16 and 26 x 32 out of that until I twigged that 832 x 75 = 62400.
So I tried ((50 x 25 x 10 x 5) - 100) / 75 = 832

@C4Countdown @Channel4 @HarryAA100m @ColinMurray @susie_dent @RachelRileyRR (100 x 1) - (50 x 2) + 75 + 25

[Mark the Math @MarkK58]

@C4Countdown @Channel4 @ColinMurray @susie_dent @RachelRileyRR The numbers game that evaded RR:
100 25 10 5 8 7 , target 926

(25 x 5) + 10 + 8 = 143
143 x 7 =1001
1001 - 75 = 926

@C4Countdown @Channel4 @DJSarahJane @ColinMurray @susie_dent @RachelRileyRR Not too sure about that first teatime teaser : LEOHEARS.
There's an obvious rude anagram here as well.

@SkyandTelescope This old map, as well as being mirrored, includes two now-deleted constellations, the Little Triangle and the (Northern) Fly.

@YesterdaysBrit1 The cunning and devious Albert had Harold exactly where he wanted him, upstaging him every time he tried to outdo his "dirty old man" dad.

There wer some episodes (Xmas '74, Upstairs Downstairs) where Harold was victorious though.

@Demo2020cracy I can still make out the constellations of Auriga and Taurus (wth Jupiter visiting) and the Pleiades top right.

@larryjones Makes me think of T.C. and Officer Dibble.

@MrsStewartMaths @StudyMaths This blooper from a past paper is one of the worst.

@MorrisMaths359 @StudyMaths The LCM example has all the pairs of numbers mutually prime, so the LCM happens to be the product.
Better would have been
3 and 10 (mutually prime)
6 and 10 (a common factor >1)
6 and 12 (smaller number a factor of the larger)

[Mark the Math @MarkK58]

@MorrisMaths359 @StudyMaths The shape examples happen to give the same numerical values, but could be improved to ask the student to show all working and state the units of the answer.
