## Real-life Applications

- Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
- Combining like terms is one of the most fundamental simplifications procedures. Virtually all equations employ some kind of collecting like terms.
- Combining like terms can be viewed as a justification for getting common denominators to add a (although circular). The different denominators are different "terms."
- Negative numbers are used to describe values on a scale that goes below zero, such as the Celsius and Fahrenheit scales for temperature.
- Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
