Divisibility Test
Divisibility Test is the topic in which we are going to see the shortcuts to predict one number is divisible by another number with out doing too much calculation.
Two or more sets are said to be disjoint if they have no common elements.Disjoint-sets are also known as non overlapping sets.
For example:
A={2,4,6,8} and B={1,3,5,7}. Here A and B have no common element. So A and B are disjoint sets.
In mathematics we have different forms of numbers. The classification of numbers are natural number, whole number,Integer, fractions, decimals, percents, irrational and rational numbers, real numbers and complex numbers.
Dividend:

For example 8 ÷ 4 = 2
Here 8 is the dividend

“Mathematics, without this we can do nothing in our life. Each and everything around us is math.
Math is not only solving problems and finding solutions and it is also doing many things in our day to day life. They are:
It subtracts sadness and adds happiness in our life.
It divides sorrow and multiplies forgiveness and love.
Some people would not be able accept that the subject Math is easy to understand. That is because; they are unable to realize how the life is complicated. The problems in the subject Math are easier to solve than the problems in our real life. When we people are able to solve all the problems in the complicated life, why can we not solve the simple math problems?
Many people think that the subject math is always complicated and it exists to make things from simple to complicate. But the real existence of the subject math is to make things from complicate to simple.”
