Filming 'It's Not Rocket Science' has made me realise I'm missing the part of my brain that warns me about danger because - even though the tasks are terrifying - I find it really exciting.

I think the word 'celebrity' is stupid.

I like being known for being good at maths and having a brain. If I've been asked to do something but it's not relevant to me, I don't do it. I'd feel a bit of an idiot just turning up in a dress.

Very fitted dresses look much better on TV, even though in reality they might be so tight that I can barely move in them.

Winter is my favourite season for clothes because I'm happiest wearing knitted dresses, leggings, and Uggs.

I'm 5ft 7in tall and a size six to eight on top and eight to ten on the bottom. Consequently, I get a lot of my clothes altered to fit, as I am always between sizes.

I've had the 'Countdown' theme-tune as my mobile phone ringtone for years.

I've been a fan of 'Countdown' for as long as I can remember, and this is a dream job.

I only applied for 'Countdown' as a bit of a laugh while applying for lots of other graduate jobs. I've had some amazing opportunities, and I've loved every minute.

The paso doble is my favourite dance on 'Strictly,' so I'm so pleased I get to do it.

Being bad at maths shouldn't be something to brag about, and I'm glad people are waking up to this, but there's no reason be embarrassed to look for help when it comes to numeracy.

'I'm a Celebrity' is not my cup of tea whatsoever. I don't like the animal cruelty in it, to be honest.

For my 21st birthday party, I had a 'Strictly'-themed fancy dress.

When I was at uni, our whole college bar would gather around the quiz machine for a few games every night.

The best thing about 'Strictly' is it doesn't matter what level you start at, if you've never put a foot in front of the other in your life.

University was a shock to the system. At times, I really thought I couldn't do it. It's the same with 'Strictly.' I'm completely out of my comfort zone.

My parents supported me through university, and after I graduated, I got a job as an analyst at a price comparison website called TotallyMoney.com.

From my personal experience, because I'm in a relationship, on paper I would never have imagined - I'm an Essex girl, maths geek who likes football, and I've ended up with a Russian ballroom dancer, and I guess the things you think are important, especially when you're younger, turn out not to be.

I'm really interested in male and female brains and whether female brains or male brains are better at maths.

It's always flattering when you get compliments, but it's more of a measure of who you are at the time than anything else.

You sit men and women down and give them a maths test, and they will do fairly equally. Then you set up the same test, but with different people, and make them tick a box to say whether they are a man or a woman, and the women do significantly worse in the maths test than they did previously in a group set.

I cycle, especially in warm weather. If I have a meeting in town, I would rather cycle than go by car.

I like to do things where you do learn something and go on a journey, such as 'Strictly Come Dancing.'

We go to the banya, the Russian spa. And you go into the sauna, which is really hot, much hotter than a normal sauna, and then they beat you with branches.

There's no reason for men to be better at maths than women - it's just about our perception.

I think there is a real negative attitude to splitting up with someone in our society, but it is good to stay friends.

I use a stylist, which wasn't something I imagined I'd ever do, because I like shopping, but because we prerecord 'Countdown,' I don't want to wear something that everyone has from the high street by the time the programme goes out.

God, I don't think of myself as gorgeous at all!

There's no such thing as a 'maths brain.' Anyone can be numerate; it's just a matter of confidence. There are so many opportunities to improve your skills during everyday life, doing even a little a day can make maths feel more familiar and less scary.

When I was little, I carried a book of times tables around everywhere and always tried to get the best score. I like the fact that you don't need any tools, only your head. I also enjoy rules and, with maths, you are either right or wrong.

People have got their opinions, and you can't please everyone.

The brain is muscle. If you don't exercise it, it will get slow.

I was on 'Strictly' because I was getting stage fright. I was taught that I had to imagine what a good outcome would be and be happy with it.

I was with my ex-husband for eight or nine years, and we became good friends. I met him at university, and our relationship ended. We are still good friends.

I would just like to learn to control my limbs.

My parents encourage me to save, but I do buy the odd thing that I wouldn't tell them about.

I take vitamin C and zinc every day to keep colds at bay. I also take calcium tablets to supplement my lack of dairy, and d-mannose, a cranberry extract thought to be good for women's health.

I never Google myself because that way madness lies.

People can underestimate you when you're blonde and from Essex, but it's easy to shut that down. I used to get dumb blonde jokes when I was 18, but when I replied that I was studying maths at Oxford, it usually shut them up.

In school productions, I was always villager No. 7. I was never at the front of the stage dancing and never had any lines.

I have had a problem with food intolerance since I was eight.

Maths is like a ladder - if you miss the first few rungs, you can't jump up, so start with the basics.

I've always been clumsy, the one who knocks glasses over.

I'm very excited to be joining the 'Gadget Show' family. I'm always keen to try out new gadgets, so it's going to be brilliant to be able to get my hands on the latest models and test them on behalf of the viewers.

I'm a massive football fan, so when Ladbrokes approached me and asked me to take a look at the statistics, I jumped at the chance.

The me on '8 Out Of 10 Cats' is the side I'd show to my mates.

Before 'Countdown,' I'd never even met anyone who was on TV.

A review of maths teaching is a great thing, but it's a complex issue, and often the damage is done in the very early years of education.

Digital exclusion is a difficult issue for families across the whole of the U.K., including my own. I love seeing my nan, but with such a busy schedule and a long distance between us, I don't get to see her nearly as often as I would like.

I never would've thought of going on 'Strictly,' I mean, I went on because it's my mum's favourite programme in the world.
