### Is the sum of two square consecutive numbers an odd number?

Yes. One has to be the square of an odd number. The other square
has to the the square of the even number either before or after the
odd number. If this is confusing just plug in real values. In
either case, an odd times and odd is odd. Therefore one of the
squares has to be odd. AN even times an even, however, is always
even. Therefore, the second square has to be even. Thus, one of the
squares is even and the other is odd. An even plus and odd is
always odd.

###### Asked in Math and Arithmetic

### Why is the sum of two odd numbers even?

-- The first odd number is some even number plus an extra ' 1
'.
-- The second odd number is some even number plus an extra ' 1
'.
-- Add them. You get (an even number) + (an even number) + ( 2
).
That's an even number.
========================
Another mind-bending , brain-busting way to look at it :
-- The first odd number is some even number plus an extra ' 1
'.
-- The second odd number is some even number minus ' 1 '.
-- Add them. You get (an even number) + (an even number) + ( [1
- 1] or zero ).
That's an even number.

###### Asked in Math and Arithmetic

### Why does a negative integer raised to an even power always result in a positive integer?

The multiplication rule of thumb always states that a negative
number times a negative number results in a positive number.
Since an even number is always divisible by two, any value
raised to an even integer power will result in a positive
number.
However, a basic proof is presented as follows:
(-A) * (-A) = A^2
((-A) * (-A)) ^ 2 = ((-A * -A) * (-A * -A)) = A^2 * A^2 = A ^

### Is 4 an even number?

###### Asked in Math and Arithmetic

### Why do you get an even number when you add two even numbers?

An even number is always some quantity of 'twos' (2's),
and any quantity of twos is an even number.
The first even number is a quantity of twos, and the
second even number is another quantity of twos.
When you add the first quantity of twos to the second quantity
of twos,
you get a new quantity of twos.
Since the new quantity of twos is a quantity of twos,
it's an even number.
