Evaluate expressions. A variable is a letter, for example x, y or z, that represents an unspecified number. $$6+x=12$$ To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
We have learned that, in in an algebraic expression, letters can stand for numbers. When we substitute a specific value for each variable, and then perform the operations, it's called evaluating the expression. Let's evaluate the expression 3y + 2y when 5 = y. Click on the steps to see how it's done.
"Evaluate" is fairly synonymous with "solve" when used in mathematics. An example of wording is, "Evaluate the cost of six tomatoes when the tomatoes are priced at $2 each." This is a simple multiplication problem where the student would multiply 6 by 2 for an answer of $12.
