Algebra | Expanding Single Brackets | Maths with Mrs. B

The video tutorial explains the process of expanding brackets in algebra, which involves removing brackets by multiplying the term outside the brackets with each term inside. It provides multiple examples, starting with simple expressions and progressing to more complex ones involving multiple variables and squaring terms. The tutorial concludes with a challenge for viewers to practice expanding expressions on their own.
