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

Find the value of the expression.

You evaluate the expression !! :)

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.

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.

Unfortunately there is no expression to evaluate!

You evaluate it for example {-2} is 2

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.

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

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

It is called "to evaluate" the expression.

It means to substitute a number values into an expression.

It depends on the expression.

"Evaluate the expression" means replace all the letters with their numericalvalues, and then see what number the whole expression works out to be.

evaluate means to figure out the value of something

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

You convert an (infix) expression into a postfix expression as part of the process of generating code to evaluate that expression.

The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.

It is "evaluate".

"Evaluate" means to calculate - find out what value it has.

Evaluating the expression is usually used in math, and it means solve the question.

That means to look at each statement separately and evaluate after each step.
