Integers

The video tutorial explains the concept of integers using real-world examples like elevations of Death Valley, Mount McKinley, and Copenhagen. It defines integers as whole numbers that can be positive, negative, or zero, and highlights their everyday applications, such as in temperature measurement and blood pressure. The video also covers mathematical properties of integers, including commutative, associative, and distributive properties, and illustrates the use of a number line to understand positive and negative numbers. Finally, it touches on the concept of infinite integers.
