Amazing Math Calculation Method: Multiplying 1's

in hive-128780 •  18 days ago  (edited)

In my earlier video I showed calculated by hand 111,111,111 x 111,111,111 and showed that it is equal to 12345678987654321 but I solved that using basic hand multiplication techniques and the calculation was very tedious. But in this video I show how you can calculate any multiplication that involves only the number 1 in just a few seconds! This video is a must see and you can definitely show off your calculation skills to friends!

Multiplying 1’s by each other – Simple Method

Shoutout to Collin Malone for letting me know about this amazing method after he pointed out a simple way of solving the calculation in my earlier video:

“111,111,111 x 111,111,111 = 12345678987654321 - Hand Calculation”

Example 1

11 x 111

Solution

Simple Method:

  1. Count the number of 1’s.
  2. Subtract 1 from that number; this is the number of digits
  3. Count up until the number of digits of the smaller number is reached. The next digits will be the highest number until it can be counted down to fit the number of digits from step 1.

Steem was green, Hive is red and Blurt is orange.

Interesting. I had not heard about that! I'll check it out. This is essentially where the world is going... "don't like facebook, then hardfork and create your own!"
