They will be available to adults who do not already have a GCSE grade C/4 or higher in maths.
A three-year programme which will help adults in Leicestershire improve their numeracy skills has secured £3 million in government funding.
Multiply is designed to help spread opportunity and level up the country and the council will now deliver hundreds of free courses, wrap-around support and workshops, over the next three years.
They will be available to adults who do not already have a GCSE grade C/4 or higher in maths or equivalent and need to improve their numeracy skills.
Councillor Christine Radford, the cabinet member for adults and communities, said: "Numeracy is a vital skill that has so many practical applications in everyday life, and boosting those numeracy skills improves lives.
"The £3m funding we have received from the government will allow us to roll out this important project, which will help to support people, communities and businesses. It will enable us to offer many more opportunities to level up the county."
The Multiply programme aims to increase residents' confidence with numbers, giving them the tools they need to improve their job prospects.
It also aims to improve the financial well-being of individuals and families by supporting them in managing money, becoming financially self-sufficient and ensuring parents support their children with numeracy-based homework.
