In this lesson, we learn about the order of operations in mathematics. The basic operations include addition, subtraction, multiplication, and division. The order of operations specifies what to do first when simplifying an expression with more than one operation. First, simplify within each grouping symbol, then evaluate exponents or rewrite as multiplication, followed by multiplication or division from left to right, and finally, addition or subtraction from left to right. The lesson includes various examples, and the transcript warns against common mistakes, such as assuming multiplication is always done before division.
Part 1 of Order of Operations: Explains the order of operations, what it means, and shows examples. Basic--no negative numbers or fractions.
