One in three adults, 32 per cent, say they don't have enough basic maths knowledge to help a child with  their homework - and their finances could be suffering as a result.

As many as 27 per cent of adults have faced financial issues or put off financial tasks in the last year, according to research from Barclays.

Of course, Pythagoras' Theorem and quadratic equations might not exactly translate to problems involving your mortgage or credit card rates, but they can teach useful skills such as critical thinking and logic.

Despite a number of benefits from school maths classes, they tend to be lacking in direct financial applications to help students in later life, leading to the current situation in which many adults are finding themselves.

This is Money has previously reported that financial education is falling short in schools. 

Recent figures show 84 per cent of schoolchildren want financial education to be included in the new national curriculum.

Vim Maru, CEO of Barclays UK said, 'We know that people's relationship with money starts to be formed around the age of seven so it's crucial that we are providing children with the number confidence to help them manage and grow their finances in later life.'

Figures from audience research firm KidsKnowBest reveal that 46 per cent of children aged 7-14 are worried about money and their future, with 38 per cent saying they are stressed about finances.

Eight out of ten adults believe that more resources dedicated to using maths in everyday life would improve financial confidence in the future, with the same proportion recognising that these skills are essential for making informed financial decisions.

People are at least aware of their shortcomings, with 39 per cent keen to improve their number skills, according to the research. More younger people too, some 61 per cent, said they would like to improve their numeracy skills.

Some 43 per cent said they think their finances would be in a stronger position if they had better skills and confidence when it comes to maths.

Among those aged 18 to 27, this figure is even higher, with 76 per cent saying their finances would benefit from having deeper mathematical knowledge.

Sam Sims, chief executive of charity National Numeracy said: 'We encourage everyone to have the basics of numeracy in place before they reach for their calculators, so they can understand the calculation, make sense of the numbers, and spot if something is not right.

'Having the confidence to use numbers in daily life is a vital skill - whether for work, helping children with homework, or managing money. And not feeling number confident is nothing to be ashamed of - millions of people in the UK feel the same, but everyone can improve with some practice and the right support.'

Barclays has partnered with National Numeracy to train 'numeracy champions' in 60 primary schools, which it says will help to boost the numeracy skills or 13,000 children, parents, carers and staff.

Sims said: 'Our new partnership with Barclays will help thousands of people build that confidence, supporting better decisions at home, in school and with their finances.'
