Jan 09, 2015 · That depends on how much the fraction bar expands throughout the expression. If it is the entire expression: #((6+2)-2*(3-7))/(3(6-5))=16/3# Naturally, the way to go about this is to solve the numerator first, then the denominator. Eventually, when you get the final result, you divide. But if the division only goes through only individual elements:

The factorial operation, n !, is defined as n! = n ( n – 1) ( n – 2) ( n – 3) · · · 4 · 3 · 2 · 1. In other words, you multiply the number n, being operated upon, by every positive integer smaller than n. Some values of n! are: 1! = 1, 2! = 2, 3! = 6, 4! = 24, 5! = 120, 6! = 720, and so on.

Discuss the fact that the denominator of a rational expression cannot be 0 because division by zero would lead to an expression that is undefined. (If the numerator of a fraction is zero then the fraction is equal to zero.) In each of the examples given, any letter could be used to represent the variable. That fact comes in handy if the variable pops up in a fraction, where you'll need tools like multiplication, division and canceling of common factors to simplify the fraction. When a letter like a , b , x or y pops up in a mathematical expression, it's called a variable, but really it's a placeholder...

Overview Map: Algebra & Functions 7-9 Standards:. 1ALG.4.0 Students simplify expressions before solving linear equations and inequalities in one variable, such as 3(2x-5) + 4(x-2) = 12. Since rational expressions are just fractions with variables in the denominator, we are going to start by reviewing operations with fractions that do not contain variables. Then we will move on to performing the same operations on rational expressions. Let’s start with multiplication.
