Most mums and dads admit they can't help their children with school homework...because it's too hard.
Two thirds are clueless and half try to get answers on Google, a study found.
Maths and science are the subjects parents find the hardest, leaving them embarrassed when they are unable to help, a study of 2,000 mothers and fathers found.
Algebra, fractions and trigonometry are the least favourite homework topics, while Roman history and long division also baffle parents.
Heather Smith, Marketing Director, Aviva UK, said: "The study shows that many parents suffer a lack of confidence in helping with homework and no doubt the list of topics will serve up memories of their classroom days they may not be fond of.
"However, it's important that we do everything possible to equip our children in key areas like numeracy from an early age and develop their confidence in these areas."
More than half of the 2,000 studied now wished they had tried harder at school it emerged, with maths a topic they really regretted not focussing more on.
Ms Smith added: "It's unsurprising that maths tops the list of subjects parents dread the most. As a parent myself, I know first-hand the challenges faced when it comes to helping with homework.
"With over half of parents admitting they wished they'd tried harder at school, we have a responsibility to give our children the foundation for good financial literacy in in the future."
