How do you multiply a two digit number with another two digit number without using a calculator in a shorter way and faster? I will show you a technique. Let's consider this one:
23 x 34
By usual method,
1
2 3
x 3 4
---------------
1 9 2
6 9
---------------
7 8 2
Now, let's consider the other method which is Mayan Method. In this method, you will use the straight lines and their points of intersection.
For 23, draw 2 parallel lines and then another 3 parallel lines that are all parallel to each other.
For 34, draw 3 parallel lines and then another 4 parallel lines that are parallel to each other.
Divide the figure into three sections. At each section, count the number of points which are the points of intersection.
Therefore, the answer is 782.
