Maths can be a touchy subject, some love it while others loathe it - and the maths we learned in school can be especially divisive.
Some might argue that it's not useful for certain careers, but one person who does not is Prime Minister Rishi Sunak. The UK PM has gone as far as to suggest that maths lessons should be mandatory until age 18 for pupils and students.
While there are no current plans to go ahead with this in Scotland, it has raised discussion around how helpful maths is as a life skill in the form which we learn at school.
So, with that in mind - how much maths do you remember from school? Here is a quiz that tests high school level maths.
It's GCSE level maths, roughly around the same level as the National 5 exams in Scotland in which pupils typically sit aged 15 to 16.
You are allowed to use a pen and paper to perform calculations, but no calculator, and have as much time as it takes to answer all of the 15 questions. For reference, a National 5 student will typically get an hour for the non calculator exam - although this can vary.
This comes after a tricky maths question, again for those who typically sit exams aged between 15 and 16, recently left parents stumped.
Some 92 percent of parents were unable to answer the question, and the eight percent that did got it wrong.
