Mathematics can be fun and easy if you know how. With some simple skills you can learn how to do rapid math calculations with ease. With a few tips and a bit of practice you will be able to do what seem to be complex calculations in your head, faster than your friends can do on a calculator. So dive in and become a ‘Math Magician’ within minutes.
Let’s show you a few tricks...
How to multiply any two digit number by 11
Lets say for example 53 x 11 = ?
Add the 2 digits (5 + 3) and place the answer between the two digits.
So 53 x 11 = 583 That’s it, how simple is that?
What if the two digits add up to more than 10, simply carry the 1….
39 x 11 = 429
3+9=12, add the 1 to the first digit, and place the 2 in between the two digits as before.
Multiplying 2 digit numbers where the last 2 digits add up to 10 & first digits are the same.
For example 34 x 36 = ? (first 2 digits are the same as in 3 and the last two add up to 10, 4+6 =10).
Step 1. Add 1 to first digit and multiply this by first digit (3+1=4) 4*3=12
Step 2. Multiply the second digit by the second digit 4x6=24
Step 3. Place the two totals together and you have the answer 1224
So 34 x 36 = 1224
Squaring any two digit number ending in 5
For example 95x95 = ?
Multiply first digit by first digit + 1, and then add the number 25 on the end
9x10=90 then place 25 on the end = 9025
These are just a few of many simple methods which can make mathematical problems much simpler to process in our heads. These can be used in every day life as well as for showing off in social gatherings.
It’s amazing to think that these tricks utilise techniques that are believed to have been formed a few thousand years ago as a branch of Hindu mathematics in northern India. These ancient Indian texts contain 16 Vedic sutras which together describe ways of solving all sorts of mathematical problems. Venkatraman Shastri (born 1884) brought Vedic math to the modern world through his book titled “Vedic Mathematics”.
We would be interested to know if these Vedic math techniques are actually taught today in schools anywhere around the world. None of us here at LearnByCam were taught this way, but we wish we were. Please leave a comment if you were taught the Vedic methods.
