Why do we simplify numeric expressions

The video tutorial emphasizes the importance of simplifying mathematical expressions to make problem-solving easier. The instructor explains that mathematicians prefer simplicity and demonstrates this through examples involving numeric expressions, square roots, and exponents. The tutorial highlights the use of order of operations, specifically PEMDAS, to simplify expressions effectively.

Why do mathematicians prefer to simplify expressions?

• To make calculations more complex

• To avoid dealing with unnecessary numbers

• To make problems harder to solve

• To increase the number of steps in a problem
