Mathematics can be fun to anyone. Its up to how you response so that you can. Many say that math is hard but not with those who are equipped with the high IQs to withstand complexities of numbers. Those who hate math said that MATH is an abbreviation for Mental Abuse To Human, but those who love math said, Math is FUN.
For me, it is somehow true that math is hard particularly on me who is taking up the course of Engineering. In the world of learning, math evolves as we go deeper beyond and become more challenging.
I am not snapping out the fun out of you this summer. I just want to share a little math trick to you that I know some of you are already familiar with but I know mostly are not particularly onto it. I learned it when I was grade three student with the help of my mother. This may help you teach your little brothers, sisters, cousins, or kids in a fun way. This might help them do better in multiplication. And also they might go exited to use this on the next school year they are going next.
So what is Multiplication by the way?
It is a mathematical operation that is at its simplest abbreviated process of adding an integer to itself a specified number of times and that is extended to other numbers in accordance with laws that are valid for integers.
So let’s talk also about the history of mathematics way back to Maya civilization as a sort of trivia where math played a big role in our society and how it is very useful.
The Maya developed astronomy and math to a high level. Maya astronomers carefully observed the positions of the planets and stars. Based on Earth’s orbit around the Sun, they learned that a year was 365 days long.
The Maya invented a system of math based on the number 20. Using this system, Maya astronomers designed a calendar that divided the year into 18 months of 20 days each. To these 360 days, the Maya added 5 “unlucky” days at the end of the year.
The Maya calendar was complicated and could only be read by people with special training. But for many centuries, the Maya calendar was the most accurate calendar in the world!
Enough with that! Let's continue.
This trick can be only applied in multiplying numbers 6 to 9. This would lessen the amount of numbers you must memorize in multiplication.
First you must already memorize the multiplication accounted 1 to 5. And then it is easy to you when it comes to 6 to 9.
Example: 6 by 6
=>when multiplying, put together the tips of both fingers that corresponds the number you are desired to multiply
=>then count as equivalent to 10 each finger which are tip to tip and below it
=>after that multiply the remaining fingers above and add the result to the result below
