Order of Operations and Simplification

This video tutorial explains the order of operations in mathematics, using the acronym PEMDAS to guide the process. It covers the four main steps: simplifying inside parentheses, handling exponents, performing multiplication and division from left to right, and finally, addition and subtraction from left to right. The tutorial includes several examples to illustrate these steps, with a focus on using a calculator for verification. It also addresses expressions in fraction form, emphasizing the importance of simplifying the numerator and denominator separately.

What does the 'P' in PEMDAS stand for?

• Parentheses

• Powers

• Proportions

• Products
