Multiply 3423 with 1924:

Don't be scared. It is easy. Let's do convolution method because it is easier:

 |  3  4  2  3
--------------
1|
9|
2|
4|

 

Now, multiply each row and column, remember multiplication table. No need to use any carries.

 |  3  4  2  3
--------------
1|  3  4  2  3
9| 27 36 18 27
2|  6  8  4  6
4| 12 16  8 12

 

This is the only time you need to use your brain. Add together the numbers, diagonally, from bottom right to top left. Place the result as an addition, for each diagonal, the result is shifted (multiplied by 10).

 |  3  4  2  3

Now, do the addition with carry. The result is the product of the multiplication!

          4700

       3100000

--------------
       6585852

 

3423 times 1924 equals 6585852.

It is clever tho. :D

 

Calculator is way faster and less headache.

 

Let's do multiplication using long multiplication (oh no, this is what you teach school children, and I have already forgotten how to do it! Also, is that really the name? Anyways):

Multiply 3423 with 1824:

          ____
          3423
        * 1824
        ______

First, um....

          __1_
             3
        *    4
        ______
             2

Maybe this?

          __1_
            2 
        *    4
        ______
            82

I don't like how this is going....

          __x_
            2 
        *    4
        ______
            92

I'm just running with this now. I don't care if I get it wrong...

          1___
           4  
        *    4
        ______
           692
          1___
          3   
        *    4
        ______
         12692
          x___
          3   
        *    4

             3

            6.
          ____
            2 
        *   2 
        ______
         13692
           46.

The alignment and placement of carries are really annoying from here on...

          ____
           4  
        *   2 
        ______

             3
        *  8  
        ______
         13692
         6846.
           4..  
         12___
            2 
        *  8

        ______
         13692

       6243452

 

And, to check if it is right, long division time..... No. Calculator.  6243452 / 3423 = 1823.9707858603564125036517674554

 

 

I messed up. Where? I don't care. I rest my case.

Ever wanted to do subtraction without the chain of borrows?



  45000000000
- 11653653643
_____________

This is going to hurt...

   oh noooo!
  ___________
  45000000000
- 11653653643
_____________
            7

 

Well, just subtract 1 from each number, and it is super easy!!! Since the difference between two numbers are the same if you subtract the same from both:
 



45000000000 - 1 = 44999999999

11653653643 - 1 = 11653653642

 

And now, this is easy!
 



  44999999999
- 11653653642
_____________
  33346346357

 

And this is why we are not taught this in school: Because teachers are evil and want us to suffer.
