In real life, integers are used in different sports, and when people utilize banks to deposit or withdraw cash, read a temperature below zero, calculate a loss or gain in stocks or look at a posted speed limits. When a person withdraws $50 from a bank account, the total in the account goes down by the negative integer of 50. Another example is when temperatures are either very low or high.
Integers are defined as the set of whole numbers that include both positive numbers and their opposites. A reading below zero is given by a negative integer, while a temperature, such as 100 degrees Fahrenheit is a positive integer. In sports like hockey, there are plus-minus statistics that are calculated for players. A mountain's elevation is another example of positive integers.
