Write an algebraic expression for the product of x and 7

Factoring algebra Video transcript - In earlier mathematics that you may have done, you probably got familiar with the idea of a factor. So for example, let me just pick an arbitrary number, the number We could say that the number 12 is the product of say two and six; two times six is equal to A variable is a letter that represents a number. Don't let the fact that it is a letter throw you. Since it represents a number, you treat it just like you do a number when you do various mathematical operations involving variables.

Evaluating an Expression You evaluate an expression by replacing the variable with the given number and performing the indicated operation. Value of an Expression When you are asked to find the value of an expression, that means you are looking for the result that you get when you evaluate the expression.

So keep in mind that vary means to change - a variable allows an expression to take on different values, depending on the situation. For example, the area of a rectangle is length times width.

Well, not every rectangle is going to have the same length and width, so we can use an algebraic expression with variables to represent the area and then plug in the appropriate numbers to evaluate it.

So if we let the length be the variable l and width be w, we can use the expression lw. If a given rectangle has a length of 4 and width of 3, we would evaluate the expression by replacing l with 4 and w with 3 and multiplying to get a value of 4 times 3 or Plugging in the corresponding value for each variable and then evaluating the expression we get:Phantasmal Media: An Approach to Imagination, Computation, and Expression (The MIT Press) [D.
