You replace variables by their assigned values, then do the calculations.
to find the value of an expression, you need to
you have to use "order of operations"
you have to use "order of operations"
Use factorials.
To find the value of an algebraic expression is to evaluate it.
You evaluate the expression !! :)
Replace each variable in the expression by its value and then find the value of the expression.
You replace variables by their assigned values, then do the calculations.
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
It is called "to evaluate" the expression.
You cannot find the answer to an expression!!! An expression needs to be EQUATED' to a value, for another value to be found. 2x^(2) + 5x + 12 is an EXPRESSION. Impossible to find an value for 'x'. However, 2x^(2) + 5x + 12 = 0 is an EQUATION and a result can be calculated.
Inequality
