/ Preparation Maths Number SystemAll integers which are divisible by 2 giving remainder as zero, in the end, are known as Even Numbers whereas the numbers not directly divisible are referred to as odd numbers. Even numbers include 2,4,6,8,10,... and so on.
To check if a number is even, we have to check if the number always ends with 0,2,6,4,8, then, it is even.

Properties of Even Numbers
1.Property of Addition: On adding two even numbers, the resulting sum is also an even number.
Suppose a and b as two even numbers. On adding a and b,
a(even number) + b(even number) = sum(even number)
On adding an even number with an odd number or vice-versa, the resulting sum will always be an odd number.
a(odd number) + b(even number) = sum(odd number)
- Property of Subtraction: On subtracting two even numbers, the resulting difference between the two numbers will also be an even number.
x(even number) - y(even number) = difference(even number)
On subtracting an even number from an odd number or the vice-versa, the resulting difference will always be an odd number.
x(odd number) - y(even number) = difference(odd number)
- Property of Multiplication: On multiplying two even numbers, the resulting product will also be an even number.
p(even number) * q(even number) = product(even number)
On multiplying an odd number with an even number, the resulting product will always be an even number.
p(odd number) * q(even number) = product(even number)
