For example, the area of a rectangle is length times width. Step Click in the text to place the cursor where you want to write the algebraic expression. Microsoft Word makes it easy to type math expressions. 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 Evaluating an Expression You evaluate an expression by replacing the variable with the given number and performing the indicated operation.
Share on Facebook Writing algebraic expressions often requires more than typing the simple numbers and letters found on your keyboard. 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 keep in mind that vary means to change - a variable allows an expression to take on different values, depending on the situation. Since it represents a number, you treat it just like you do a number when you do various mathematical operations involving variables.
So if we let the length be the variable l and width be w, we can use the expression lw. 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.
Fortunately, both Microsoft Word and provide a special set of equation tools that help you form algebraic expressions without much trouble. Word will create a new equation field, in which you can form the algebraic expression.
A variable is a letter that represents a number. Use the characters in the Symbols menu on the Ribbon to add special mathematical symbols.
Video of the Day Step Type any numbers in the expression using the number keys on your keyboard. Step Click the "Insert" tab on the Ribbon. What about exponents, radicals, mathematical characters or even just fractions? Rather than hunting through the expansive Symbols menu to find math characters and then using text boxes, format buttons and different font characteristics, you can use the equations tab on the Ribbon, which groups together all the characters, symbols and functions you need to create even advanced, complex expressions.Writing Algebraic Expressions is presnted by Math Goodies.
