Question

sum of two odd numbers is always even.State true or false.Give reasons​

Answer 1

Yes it is true

for example 1+1=2

odd + odd = even

Answer 2

Sum of two odd numbers is always even. - True

Proof — let x and y be two even numbers

So, x and y are mutiples of 2.

x=2a and y=2b ; where a and b are any two integers.

Now x+y=2a+2b= 2(a+b)

This means x+y is also multiple of 2.

So x+y is an even number.
