Magic Numbers: Hannah Fry's Mysterious World of Maths (BBC4, 9pm)

FOR many pupils, maths can be a rather dull subject.

But of course with the right teacher, even the most baffling subject can suddenly become as clear as day. Over the years, flame-haired numbers wiz Hannah Fry has done a fine job of introducing the issue to folks who used to spend more time thinking about pies than pi. In the first of the new run, she looks at whether maths was invented or discovered, and examines rules of maths found in nature from flower petals to a virus structure. Plus, there's a look at the invention of zero and other imaginary numbers. From the woman who penned The Mathematics of Love, finally a show about maths that even the most numerically challenged viewer should adore.

Bad Move (ITV, 8pm)

STEVE has finally got his driving licence back and promises Nicky that his speeding days are over.

In spite of her doubts, it seems that he has indeed turned over a new leaf. Even when he's conned into a trip to the superstore with Alice, the devious old lady from the village, Steve manages to make the long journey across the moors without breaking the speed limit. So when Nicky's father Ken is made President of the Garthdale Bowls Club, Steve's offer of giving him a lift to the inauguration ceremony goes down well. Ken is even more impressed when Steve persuades Grizzo to lend him his brand new, high-powered sports car for the occasion.

Am I a Murderer? (ITV, 9pm)

Although police launched a missing persons investigation, he was never found, and detectives concluded that Fred had committed suicide.

Janet was convinced she had committed a murder. With contributions from her, Fred's daughter Lynette, psychologists and police officers, this film explores whether Janet's recollection of committing the murder could be true.

Trust (BBC2, 9pm)

RIDLEY SCOTT'S version of the same story may have been covered in All the Money in the World recently, but this take on the Getty dynasty has been one of the TV highlights of the year.

One of the key reasons is a terrific performance from Donald Sutherland as seasoned tycoon J Paul Getty, who refuses to give in to blackmail when his grandson is kidnapped. In episode five, Primo and Leonardo mobilise the local community, while Little Paul and Angelo try to agree on their next steps. The cast includes Hilary Swank, Harris Dickinson, Brendan Fraser and Andrea Arcangeli. It's ably directed by pop promo veteran Dawn Shadforth, who has also been working on a mini-series based on the His Dark Materials saga.

The Apprentice (BBC1, 9pm)
