Are you able to easily answer math problems without the need to think hard? Or do you even kind of person who had tried desperately but have not been able to resolve the matter at all? If you think math is difficult, so starting today you do not have to worry anymore.
This versatile 4 multiplication trick not only helps us to solve problems quickly, but even those can not even math can learn easily. Many people feel this formula is so magical!
Come see 4 this particular technique!
1. Multiplication of two variables (see the picture below)
2. How Indian calculation (see the picture below)
Separate both the multiplier 「21」 into 「2」 and 「1」, then drawing parallel slashes from top right to bottom left.
Then separate the figures also 「13」 into 「1」 and 「3」, then the image is also slashes are aligned from top left to bottom right.
Then find some connecting point between the lines that coincide and divide it into three parts. Then count the number of points that each part and merge into 「273」
3. Multiplication 11 with two variables (see the picture below)
This is the most simple of all. This method can be used for all two variable numbers multiplied by 11.
From the examples below, separated number 「35」 into 「3」 and 「5」 then add (3 + 5 = 8). The result 「8」 was immediately put in the middle of the number 「3」 and 「5」 into 「385」
4. Can not remember the multiplication formula? (See the picture below)
Take out your hands, and then we try to calculate 7 × 8, left hand is 「7」, your right hand is 「8」, then the hand into three parts.
Add the number of fingers on a small section below, the total is 「5」 and then multiplied by 10 to 「5 × 10 = 50」
For the upper hand into 2 parts 「3」 and 「2」 then you 「3 × 2 = 6」
Then add all 50 + 6 = 56, and the answer is 「56」
