# Adding Fractions With Like Denominators 3

This math video tutorial gives a step by step explanation to a math problem on "Adding Fractions With Like Denominators 3".

The first rule of adding fractions is that only like denominators can be added. Unlike denominators must first be converted to like denominators.

Addition is the basic operation of arithmetic. In its simplest form, addition combines two numbers, the addends or terms, into a single number, the sum.

Adding more than two numbers can be viewed as repeated addition; this procedure is known as summation and includes ways to add infinitely many numbers in an infinite series; repeated addition of the number one is the most basic form of counting.

Addition is commutative and associative so the order in which the terms are added does not matter. The identity element of addition (the additive identity) is 0, that is, adding zero to any number will yield that same number. Also, the inverse element of addition (the additive inverse) is the opposite of any number, that is, adding the opposite of any number to the number itself will yield the additive identity, 0. For example, the opposite of 7 is (-7), so 7 + (-7) = 0. Addition can be given geometrically as follows.

If a and b are the lengths of two sticks, then if we place the sticks one after the other, the length of the stick thus formed will be a+b

The first rule of addition of fractions is that only like denominators can be added. Unlike denominators must first be converted to like denominators.

# Denominator

Denominator is the name for the bottom part of a fraction. It tells you how many equal parts make up a whole, and is also used in the name of the fraction: "halves", "thirds", "quarters", "fifths", "sixths" and so on. The reduced fraction for a rational must have an integer denominator. By convention the denominator is made to be positive (any factor of -1 can be multiplied out into the numerator).

The denominator of a fraction can never be zero since a number devided by zero is not defined.

# Fractions

In mathematics, a fraction is a concept of a proportional relation between an object part and the object whole. Each fraction consists of a denominator (bottom) and a numerator (top), representing (respectively) the number of equal parts that an object is divided into, and the number of those parts indicated for the particular fraction.
