Both contestants are Maths experts, but struggled with this - can you get it? Join us today on Channel 4 at 2:10pm with Christopher Biggins and colin murray, Susie Dent, and Rachel Riley MBE 💙 Countdown | Mon-Fri | 2:10pm on Channel 4 #Countdown

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR 9 x 100 = 900 25 - (5/5) = 24 900 + 24 = 924 For a change, that's one I would have actually got inside the 30 seconds.

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR Surely easy? 9x100 =900 Add 25 =925 5/5 =1 925 - 1 =924

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR 9x100 = 900 900+25 = 925 5 div. 5 = 1 925-1 = 924 I’m totally rubbish at maths and I surprised myself by getting it before the clock finished. Unless it requires two or three numbers at max, I’m rubbish with the numbers round lol 😂

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR I’m always worried when I think I’ve got it and the Champs haven’t that I’ve done it wrong but I don’t think I need to worry this time

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR Surely it's as simple as 9x100+25-(5/5)

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR I got it n I’m hopeless at maths … so immediately thought I must have got it wrong … but I haven’t 🎉

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR For once in my life I feel smart at maths 😅

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR Was astounded they both had problems with two VERY easy rounds. It's the nerves...

@Channel4 @onebiggins @ColinMurray @susie_dent @RachelRileyRR That was so funny! I got it in a few seconds and when both contestants said they hadn't got it, I started to doubt myself. What a relief when Rachel agreed with my solution!
