Mastering Integer Operation Rules

Mrs. Fayne introduces integer operations, covering addition, subtraction, multiplication, and division. She explains integers as whole numbers and their opposites, excluding fractions and decimals. The video details rules for adding integers with the same and different signs, converting subtraction to addition, and the rules for multiplying and dividing integers. The lesson includes examples and uses metaphors like pirates and ninjas to illustrate concepts.
