This video tutorial covers the formal rules for adding integers, explaining how to handle integers with the same or different signs. It begins with a review of what integers are, followed by a detailed explanation of the rules for adding integers. The video provides several examples to illustrate these rules, including both integers with the same sign and those with different signs. The tutorial concludes with additional resources for further learning, such as using a number line or money analogy to understand integer addition.

What is an integer?

• A number without a fractional or decimal component
