Basic Math Concepts and Operations

The video tutorial covers basic math concepts for the TSI assessment, focusing on fractions. It explains how to reduce fractions to their lowest terms, add and subtract fractions with the same and different denominators, and convert between improper fractions and mixed numbers. The tutorial also covers borrowing techniques for subtraction and methods for multiplying fractions, including cross-reduction. Finally, it demonstrates converting mixed numbers to improper fractions for multiplication.
