Millennials have been branded the worst at maths by a study into numeracy skills.

Older age groups sailed through the nine basic mathematics questions but less than 20% of those under the age of 22 found the right answers.

The survey, commissioned by the cZeus maths app, put the 38 to 49-year-old age group at the top of the class with a 100% rating while the over-50s scored 87%.

“Younger people in the UK have an alarming issue with numbers,” says Dr Shoreh Blank, who invented the app to improve numeracy skills. “If this generation is struggling with basic figures then the economic outlook is troubling.”

cZeus Maths Challenger has been designed to reinforce classroom learning and encourage numeracy play.
