Challenge No. 2 Mental Challenge.

Hello again and I am back with another challenge. This time I am doing a mental challenge. There is a cool thing that has something to do with math. 11 multiply by any number is going to be easy peasy. Even if it is a number like: 6424587649748488594. You can tell I scrambled that out. If you used the normal multiplacation formula it would take you aaages. But with my trick it can be solved in a minute. Try this if you know addition very well. Let's take an example. 132. 132x11. It is easy. Put the 2 on the right, then add the 3 and 2 together and put it in the next digit place in front of the 2. Then 3 add 1. Put that in the next digit place. Then put the 1 on the far left side. I can work it out right now. Gimme a sec. Umm... Hmm... Ok... NANI... Gat em. The answer is 1452. Check an calculator. I'm correct right? My challenge is work out 1234567890987654321x11. Can you work it out? Send me a picture of your work to my email. See my first challenge for the email. If you already know this thing be a cookie. Your gifted. Anyways, PEACE OUT!
