Binomial formulas, integral calculus, stochastics? “Oh, I never really got that at school”, so many adults today flirt with their knowledge gaps. How bad you were at math is a popular topic in party small talk. In contrast, nobody in the land of poets and thinkers would probably like to admit to being poor in spelling or not being able to read correctly. According to a representative survey from 2020, one in five of the adults surveyed rated their performance in mathematics as below average. And about half of all respondents stated that they had problems following math lessons during their school days, half of them in middle school (grades 7 to 9 or 10). How big the gaps arewas probably particularly aware of parents of school-age children in homeschooling in the past year. WELT explains how you can improve your knowledge quickly and easily.
