Find the remainder – Vedic Algebra

Vedic Algebra

I have got a mail from some QuickerMaths follower, to illustrate usage of Vedic Mathematics in branches of mathematics other than arithmetic. This post is for that purpose only. Here I am highlighting the usage of Vedic Mathematics in finding out the remainder when an algebraic expression is divided by another.

Finding out the remainder becomes extremely easy using Vedic Maths.

So lets begin with a simple example -


Find the remainder when

x3 + 4x2 + 6x - 7 is divided by (x + 5)

Six Degrees of Separation – Let’s have some fun!!

In this post I am starting a very interesting game on QuickerMaths.com. Friends, start playing this and I am sure you will enjoy it.

To play this game let us first understand what is Six Degree of Separation.

What is Six Degree of Separation?

Six degrees of separation is an unproven theory that anyone on the planet can be connected to any other person on the planet through a chain of acquaintances that has no more than five intermediaries. The theory was first proposed in 1929 by the Hungarian writer Frigyes Karinthy in a short story called "Chains."

Which Day of the Week was My Birthday?

Find the answer to these questions instantly using the simple trick given below -

How to find the day of the week on which your birthday will fall next year?

or,

Which day of week was my birthday last year?

Today it is my birthday and somehow I was curious to know the day of the week on which I was born. Using Microsoft excel I found out that it was Thursday. I also tried listing the day of the week for all my birthdays till I will be 100 years old. I noticed a very simple but interesting facts about the days on which our birthday falls.

Every year the day advances by one day from previous year. For example I was born on 5th April 1984, Thursday. On my first birthday that is on 5yh April, 1985 it will be Friday.

But on every leap year it advances by 2 days. To understand this please refer the table below -

Date Day
5-Apr-84 Thursday
5-Apr-85 Friday
5-Apr-86 Saturday
5-Apr-87 Sunday
5-Apr-88 Tuesday
5-Apr-89 Wednesday
5-Apr-90 Thursday
5-Apr-91 Friday
5-Apr-92 Sunday
5-Apr-93 Monday
5-Apr-94 Tuesday
5-Apr-95 Wednesday
5-Apr-96 Friday

As per the above table, you can see from year 1984 to 1987, every year the days were advancing by one day. But from 1987 to 1988 (leap), increased by 2 days. Then again it from 1988 to 1991 it increases by one day each year.

So with above logic, now if any one ask me what day was it on my last (2009) birthday, if this year (2010) my birthday is on Monday. It’s very simple, it was Sunday. And next year (2011) it will be Monday. After that (2012 – leap year) it will be Wednesday as on a leap year it will increase by 2 days.
