Order of Operations and PEMDAS

The video tutorial explains the order of operations in mathematics, emphasizing the four main steps: simplifying within parentheses, handling exponents, performing multiplication and division from left to right, and finally, addition and subtraction from left to right. It clarifies common misconceptions about the mnemonic PEMDAS, highlighting that multiplication and division, as well as addition and subtraction, share the same priority and should be processed sequentially from left to right.

What is the first step in the order of operations?

• Simplify exponents

• Multiply and divide from left to right

• Simplify within parentheses

• Add and subtract from left to right
