When each variable in an algebraic expression is replaced by a numerical number and applying the appropriate properties or rules to simply, the algebraic expression takes on a numerical value, such a process is called evaluating algebraic expression.

It's like playing a game, there are certain rules we have to follow in order to evaluate an algebraic expression.

The order of operations rules:
1. Perform all operations in parentheses first.
2 Simplify all exponential expressions.
3.Perform multiplication and division as they occur, moving from left to right.
4.Perform addition and subtraction as they occur, moving from left to right.
