This tutorial will show you how to add decimals with various decimal places. It will help you learn how to line up the decimals and even show you where to place the decimal place in the sum.

Adding decimals video involves adding decimals, addition, addition of decimals, arithmetic operations, decimal addition, decimals, number sense, numbers, operations, operations with decimals. The video tutorial is recommended for 1st Grade, 2nd Grade, 3rd Grade, 4th Grade, 5th Grade, 6th Grade, 7th Grade, and/or 8th Grade Math students studying Algebra, Geometry, Trigonometry, Probability and Statistics, Arithmetic, Basic Math, Pre-Algebra, Pre-Calculus, and/or Advanced Algebra.

In order to add decimals, you should

- line up the decimal points of the addends
- if necessary, place zeros to the decimal places of each number to match the number of decimal places of the number with most decimal places
- add the number by following the rules of adding whole numbers
- place the decimal point to the result lined up with the addends

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
