Evaluating
Algebraic Expressions
An
algebraic expression is a finite additive combination of any number
of terms, such as .
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.
Ex
1:Perform
the indicated operation: .
