Multiplying by 1 is an example of the identity property. Any number times 1 is equal to that number. Therefore, we don’t always need to write the one because 1 x gw = gw factor product quotient coefficient term variable

This will be collected. § What is the difference between simplifying and expanding? ú When we simplify the expression, we get rid of the operation symbol for multiplication and we write the factors next to each other. Sometimes we might have to multiply numbers together before writing it next to the variable(s). Expanding means that we write the expression as a product of the factors using the “•” symbol for multiplication. § How would you describe the following terms? 1. Factor: A number or variable that is multiplied to get a product. 2. Variable: A letter used to represent a number. 3. Product: The solution when two factors are multiplied. 4. Coefficient: The factor that multiplies the variable.
