# How to learn to multiply

## How to learn to multiply Here are some fun tips and advice that will help you master the multiplication table

u Lesson 1 -. Multiplication is repeated addition of / U . Br
Multiplication is a quick way to add number of digits. exercise, it is best to use the game. 3 x 5 means adding three digits to five times each, or 3 + 3 + 3 + 3 + 3
6 x 4 is the addition of number 6 in it four times, or 6 + 6 + 6 + 6
u Lesson 2 -. Multiplication is commutative / u Multiply
replacement, ie, it does not matter what the first number in the calculation.
result will be the same.
3 x 5 = 5 x 3
4 x 7 = 7 x 4
1 x 9 = 9 x 1
u Lesson 3 -. Zero / u
fact that repeated multiplication of this otherwise so
0, x 3 = 0 + 0 + 0 = 0
0 x 7 = 0 + 0 + 0 + 0 + 0 + 0 + 0 = 0
and alternating, so
0 x 4 = 4 x 0 = 0 0
x 9 x 9 = 0 = 0
As you can see all the multiplication by zero is always zero
u Lesson 4 - mine. / u
Back on the assumptions that the lessons that multiplication is repeated addition:
1 x 4 = 1 + 1 + 1 + 1 = 4
1 x 2 = 1 + 1 = 2
1 x 5 = 1 + 1 + 1 + 1 + 1 = 5
3 x 1 = 3
9 x 1 = 9
Chapter 2, which says that multiplication is commutative:
1 x 4 = 4 x
1 = 4 1 x 8 = 8 x 1 = 8
concludes that any number multiplied by 1 gives the same result, the initial number,
u Lesson 5 -. good news / u There are 100
multiplication rules for learning, what is happening is not good news. At this stage, the good thing is that you can no longer be multiplied by 0 and 1, which you have in mind for 36 of these rules by
in Chapter 6 -. Better news / u
At this stage, the remaining 64 reguĊki to learn that do not contain either zero or one. better news is the existence of alternating multiplication, that is, if you learn the 3 x 4 You can skip school 3 x 4, the result is exactly the same so you do not have to worry about the following 28 rules
u Lesson 7 - the best news ... / u
At this stage there is no zero ordinances, and they commutativity, leaving 36 of the original 100th best news is the existence of simple tricks that will help you learn another rule. in later lessons.
seafront Lesson 8 -. steam / u Since
2 x 4 = 4 + 4 = 8
2 x 3 = 3 + 3 = 6
2 x 5 = 5 + 5 = 10
multiplication is commutative, by:
4 x 2 = 2 x 4 = 8
8 x 2 = 2 x 8 = 16
Any number multiplied by 2, is simply doubled,
2 x 7 = 7 +
7 = 14 6 x 2 = 6 + 6 = 12
u Lesson 9 - Fri .. / u u
Method # 1 / u If you can count
five, this method is very simple for you
3 x 3 5 is five, and so count as five, three times -. 5, 10, 15 and 15 are exactly correct result
6 x 5 6 Friday and mean also counted as five or six times - 5, 10, 15, 20, 25, 30 the correct answer is 30 because the rule of alternation
:
5 x 3 = 3 x 5 = 15
5 x 6 = 6 x 5 = 20
u method number 2 / u
calculate the second number is not to act in five. Take half the number that you multiply five and add it to zero. This technique works because the number of 5 is located in the middle of a series of numbers from 0 to 9 Therefore
5 x 6-6 of the second -
take half of the total number of 6-3 -
write her Zero - 30
5 x 8
Take half the number of 8-4 -
Write her a zero - 40
But if you multiply five by an odd number, subtract from it. another number one, and this reduction is half then add the fifth, for example :
5 x 7-7 is an odd number - subtract
1-6 -
Take half of that number - 3 - Adding
after 6-35
5 x 9
subtract 1 from No. 9 - 8 - Take half
8-4 -
write the 5 & ndash, 45
u Lesson 10 -. Nine / u u
Method No. 1 / u
finger method.
put on the table before him, both hands
Your fingers are the numbers from 1 to 10
to calculate 4 x 9, wrap your finger under No. 4
fingers on the left end of ten, which in this case 10, 20 and 30 On the other hand, the fingers on the right side of the folded form of one number, in this case 1 to 6 To get the most from each side, or 30 and 6, which together gives the result of 36th
practice for other examples of 9
u Lesson 11 - Nine - Method / u
Method a seizure
Subtract 1 from the number you multiply 9th
9 x 5 -. 5-1 = 4 -
first digit is 4, the second must be the sum of 4, in order to do nine, so
4 + _ = 9 - 5 -
last digit 5, which is
9 x 5 = 45 9 x 8
8 - 1 = 7 and 7 is the first digit
7 + 2 = 9, and 2 is the second digit
9 x 8 = 72
