you get an odd number all the time
e.g.
1x1= 1
57x3= 171
21x21= 441
47x35= 1645
Even square numbers are even, by definition. Two even numbers multiplied together give an even number so no, they cannot multiply to give an odd number. You have to multiply an even number by an odd number to do this.

You will always get another odd number.
Yes - while multiplying odd numbers by even numbers will always produce an even result.
Let E1 and E2 be two even numbers. Then (E1+1)(E2+1) will be the product of two odd numbers. We have E1*E2 +E2+E1+1. Now when we add or multiply even numbers, we get even numbers and we add 1, it's odd.
Square numbers have an odd number of factors.

Both odd and even numbers may have odd numbers as factors.
When you add them, you always get an even number; when you multiply them, the result is always odd.
