Mastering Order of Operations with Integers

This video tutorial covers the order of operations, known as PEMDAS, for solving mathematical expressions involving integers. It explains how to handle multiplication, division, addition, and subtraction with both positive and negative integers. The tutorial also demonstrates how to compare expressions, simplify them, and identify those that equal zero. Additionally, it clarifies the role of parentheses in calculations and provides practical examples to reinforce these concepts.

What does PEMDAS stand for in the order of operations?

What does it mean when integers are alone in parentheses in terms of order of operations?

• They do not influence the order

• They should be calculated first

• They should be calculated last

• They indicate multiplication

What is the result when you add a negative and a positive integer with different absolute values?

• A positive number

• A negative number

• Always zero

• The difference between the numbers with the sign of the larger absolute value

Which expression equals zero according to the order of operations?

• -24 / 6 - 4

• -24 / -6 - 4
