What Are Some Different Examples of Integers Used in Daily Life?

Integers are used in daily life when performing tasks such as recording temperature changes, taking inventory of supplies, and depositing or withdrawing money from a bank. For example, in terms of temperature changes, a rise in temperature of 30 degrees Fahrenheit is represented by the integer +30. A drop in temperature of the same magnitude would be recorded as -30.

The term "integers" refers to all whole and negative numbers, including zero. When taking a physical inventory of supplies or merchandise in a store, stock quantities are noted using positive integers. If items have been sold or otherwise disposed of, the changes would be recorded as a negative integer. This helps store owners know when the inventory is low, so they can reorder more supplies. Similarly, in banking, when depositing or withdrawing $200, the change to the account is represented as either plus or minus $200.
