Understanding Parentheses and Brackets

In this video, Super Sam introduces the concepts of parentheses and brackets in numeric expressions. The video explains their appearance and role in the order of operations, emphasizing that parentheses are solved first, followed by brackets. Through examples, the video demonstrates how to simplify expressions by solving the innermost parentheses first, then the outer brackets, and finally performing multiplication, division, and addition. The video concludes with a practice example to reinforce the learning.
