Susanna Reid has hit out at money expert and co-star Martin Lewis, warning him not to “maths shame” her.
During Tuesday morning’s instalment of Good Morning Britain, the 50-year-old snapped at 49-year-old Martin, founder of MoneySavingExpert.com, after he informed viewers that he had set a maths challenge for comedian, Dara Ó Briain, to complete later in the show.
Just before the programme cut to a break, addressing the camera, Susanna said: “We have a lot more still to come on the programme including Dara Ó Briain after 8 o’clock and Martin has a maths challenge for him.”
Martin then interjected: “He’s gonna find it easy, I wonder if other people around here will find it quite so simple,” before glancing towards Susanna in comical manner.
Susanna responds with an eye roll to camera before stifling a laugh and hitting back with: “Don’t maths shame me Martin!”
When Dara joined them a little later, he was set the mathematical challenge in question, Martin said: "So the reason we are doing this is that it's National Numeracy Challenge Week.
"Lots of people are scared of maths, functional maths, but it's really important for your day-to-day life.
"If you're [worried] about maths go to the website and you'll be able to see how good you are."
Dara Ó Briain is known for his intellect, having studied mathematics and theoretical physics at University College Dublin.
The challenge saw viewers shown three diagrams of pizzas on a chalkboard, two with 10 inch diameters priced at £10 and one 15 inch pizza priced at £10.
The question asked them to work out which option would result in the best deal for a consumer. Susanna commenced, armed with pen and paper whilst Dara opted to work it out mentally.
Giving her answer, Susanna said: “So I’ve got two children at home at the moment and if I split one pizza between them, they’d be cross, but if I gave them a pizza each, then they’d be happy. That’s my answer.”
Dara then explained, saying: “Yea you’re right and you can get different toppings but the better one to get is the big one because the area of a circle is pi r squared.
"So you take the radius and square it, so you get 225 pi amount of pizza vs two x 100 x pi of pizza, so go for the big one.”
Susanna responded: “We’re talking about maths analysis vs actual practicality."
Martin then added: "In terms of area, absolutely right, it’s just about the radius squared, so you’ve got five, which is 25, squared x 2 is 50, and 7.5 squared is 56.25, so it’s bigger.”
Martin then appeared to catch Dara off guard, re-framing the question and asking what would be better for someone who likes stuffed crust.
Dara looked surprised before replying: “Oh lord! Then you’d go to the two small ones."
