A "math primer" is an introductory resource designed to teach basic mathematical concepts and skills. It often includes explanations of fundamental topics such as addition, subtraction, multiplication, and division. These resources can be in the form of books, worksheets, or online materials, making math accessible to learners of all ages. Primers may also cover essential topics like fractions, decimals, and basic geometry. They are commonly used in educational settings, such as elementary schools, to help students build a strong foundation in mathematics. By providing clear examples and practice problems, math primers aim to enhance understanding and confidence in math.
