multiplication is learned first by memorizing what all the single digits are equal to when multiplied, such as 2 times 6. These are known as "multipilcation tables". It is a chore to have to memorize the answers to nearly 100 equations, but a series of clever cartoon music videos from "schoolhouse rock" are helpful. The series is known as "multiplication rock" and is based on the idea that if one can memorize the lyrics of their favorite pop tune and then sing along, it ought to work with multiplication as well.
Having mastered this, one has to be able to multiply far larger numbers on paper. Most people do this with calculators, but I suppose it helps to know how to walk, even though most people travel in cars.
At any rate, one begins the process by arranging numbers in stacks, for example:
12 times 26 becomes:
12
26
next, starting at the left, multiply each number in the top row by a digit in the bottom row. If this process were carried out in writing it would sound like this:
6 times two is twelve. mark the "2" and carry the "1". 6 times 1 is six, plus the one carried equals seven. Write the "7" and one now has:
72
repeat this same process with the next digit, the "2" in the "26" to yield:
24
shift the "24" one position to the left and one has:
..72
24
finally, add the two numbers. if everything was done right, the answer ought to be 312.

Well, I never had any difficulty in undestanding and accepting the multiplication tables. But here is a simple way.
Let us multiply 234 by 123. I hope this is tough enough for you.
Start with 3 of 123. 234 multiplied by 3 gives us:
200 X 3 = 600
30 X 3 = 90
4 X 3 = 12
Adding all of them we get, 702
Now let us multiply 234 by 2 which is in the second place of 123. So, that 2 is actually 20.
We multiply 234 by 2 and then add a 0 to the right of the result.
234 X 2 = 468 and adding a 0, we get 4680
Next we multiply 234 by 1 of the 123 and we get 234 but we need to add 2 zeros because 1 of that 123 is in the hundreds place.
So, let us now add all the three results of multiplication:
23400
4680
702
Adding them we get 28782 as the answer for 234 X 123
Check that the result is correct by using a calculator. It is in fact, 28782. Congrats! You have just now multiplied a 3 digit number with another 3 digit number! Not an easy task!

"Baby stuff?" Math is an art. Some people have a deeper appreciation than others.(I am of the later, lol). The best way to understand multiplication is to get used to numbers. For multiplication I suggest that you go old school with the times table chart. Do not think that it is baby ish to start at zero, one, two... and like everything else that we do in life it will become easier with practice.

I use a calculator now. But yeah... in school when I first started I memorized the multiplication tables. Just go through each number. In the beginning if I had to just add every number the number of times it was multiplied I would do that too... ex:
5 x 4
5+5+5+5=20

it took me two years too figure out multiplication don't worry it's very easy once you get it.
here is a trick I learned with the 9 tables.
hold your hands out,lets say its 9 times 6 but down the 6th figure on your hand,so you have 5 on one hand and 4 on the other now you have 54 that's your answer. it works with all the the numbers for 9.
with 5 its just 5 times 5 lets say,it's 5,5 times so you could do 5+5+5+5+5=25. it's the same process with all the numbers.
10 is very easy lets say you have 10 times 7 just add a 0 to your 7 and that's your answer you can do that with anything times 10.
7,6,8 took me a while to learn
a trick for 7 times 7 is think of the 49'Er's get it? 49 is your answer for 7 * 7
1,2,3 are very easy because they are small numbers.
with 2 its that number 2 times. so 2*2=4 because it's the number 2 twice,same with all other numbers.
hope I helped. :D

If you mean multiplication of numbers...
I sometimes see it as a sum... and it's easier for me... like for example:
17 * 5
This means 17 added 5 times so I breke the 17 to 10 and 7.
Then I add the 5 tens and get 50...
then I add 5 sevens and get 35...
So 50 + 35 = 85
Now... if you want to multiply variables,
x * x = (x^1)(x^1) = x^(1+1) = x^2
If you multiply
(2x^2)(3x) = (2x^2)(3x^1) = 6x^(2+1) = 6x^3
Hope this can help you better understand.
God Bless!

Multiplication is a shortcut for addition. If I had to add 23 seven times I could do that, or I could multiply 23 times 7.

Start with small numbers and think of addition- make the numbers objects. For example:
6 times 2= 6 people have 2 hands
So how many hands are there total? 12
If you get confused- count one by one

Most people, including myself, commit the 1-9 multiplication table to memory in grade school. If you memorize this, you can do all multiplcation, regardless of how complex it gets.

go to a record store or on line and see if you can order school house rocks multiplication tables. That is how I learned my multiplication. It used to be a show on saturday mornings.
