Adding and Subtracting Integers

The video tutorial covers the basics of adding integers, focusing on two scenarios: when integers have the same signs and when they have different signs. For integers with the same signs, the process involves adding the numbers and keeping the sign. For integers with different signs, the process involves subtracting the numbers and keeping the sign of the number with the larger absolute value. The tutorial includes examples and clarifies that zero is neither positive nor negative.
