You evaluate it for example {-2} is 2

To "evaluate" an expression, you need to know the value for the variables.

1/2w+2

[10-(4*2)]*3

Find the value of the expression.

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?

To evaluate an expression is nothing but to operate the given expression according to the operators given in the expression if it is evaluable i.e, it could be convertable.

You evaluate the expression !! :)

Unfortunately there is no expression to evaluate!

In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.

You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.

There is nothing to "evaluate" there; that's a pure number.

Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.

Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.

5 - 2 + 11 = 14

When x = 2, 3x + 5 = 11.

It is called "to evaluate" the expression.

It means to substitute a number values into an expression.

It depends on the expression.

evaluate means to figure out the value of something

The answer is x = 5. There is nothing to evaluate there!

It is "evaluate".
