ANY INTEGER IS DENOTED BY N
IT WILL BE EVEN IF WE MULTIPLY BY 2...THAT IS 2N IS EVEN INTEGER.
IT WILL BE ODD IF WE ADD 1 TO IT..THAT IS
2N+1 IS ODD INTEGER.
PRODUCT OF 2 ODD INTEGERS IS
(2N+1)(2M+1)=4MN+2N+2M+1=2(2MN+M+N)+1=2P+1 WHERE PIS AN INTEGER.
HENCE BY THE ABOVE LOGIC THE PRODUCT IS AN ODD INTEGER.
