Review of Mathematics!

I AM A CALCULATOR~~ PLEASE USE ME!~~~

Today, let's see some questions that we can calculate using our mind, without the calculator!

For the first such question, we do addition "+"~!

1=1
1 + 1 = 2
12 + 21 = 33
123 + 321 = 444
1234 + 4321 = 5555
12345 + 54321 = 66666
123456 + 654321 = 777777
1234567 + 7654321 = 8888888
12345678 + 87654321 = 99999999
123456789 + 987654321 = 1111111110

Is very simple right? we can get those answers without the calculator!!~

Now the second question, multiplication:~~ "x"

1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 12345678987654321

After you calculated the second and third terms, then the others you can just simply write it out, without the calculator!


Remember that, CALCULATOR WAS CREATED BY HUMAN, THEREFORE, HUMAN MIND HAS THE STRONGEST CALCULATION ABILITY!

Hahas, for the time being, i just manage to give those two examples!!
Will have more updates SOON!!
Please comment yea!! Thanks!!
