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.
an odd number
Any odd number multiply with itself, or any other odd number results in odd square number.
There is nothing special about either of those. Multiply them as you would any other numbers.
Well, darling, the sum of the first 99 odd numbers is 9801. You see, you take the last odd number, which is 197, multiply it by the total number of odd numbers (which is 99), and divide by 2. Voila! Math magic at its finest.

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.
Square numbers have an odd number of factors.
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.

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.
