Order of Operations and Expressions

Mr. Buffington's video tutorial delves into the order of operations, expanding on basic concepts with more complex examples. The tutorial covers the standard rules, such as handling parentheses and exponents, and introduces advanced topics like fractions and implied terms. Through various examples, viewers learn to apply these rules to solve mathematical expressions accurately. The video concludes with additional tips and subtle rules that are often overlooked but crucial for understanding the order of operations.
