zero 152 + 0 = 152 for example
'Zero' and any other number.
Add them up. Any order (the result is always the same)
The sum of an odd and even number is always odd because there's always one left over. Think of any odd number as being any even number plus one. If you add two even numbers, the answer is always even. If you add an even and an odd (plus one), the answer is always odd.
The number of sides and vertices in any polygon is always the same.
zero 152 + 0 = 152 for example
Yes, if you add zero to any number, it will always remain itself. The value of zero is, literally, nothing, so nothing would be added to any number.
No, Numbers never stop so you can always add three zeros to any number.
Add any number to (60 minus the same number).
zero
If you add zero to any number, the sum is the same number you started with.
Congruent angles always add up to 180 degrees. The above answer is so wrong. Congruent angles are angles of the same measure. They can have any value and so can add to any number. For example, the six interior angles of a regular hexagon are 120 degrees each and they add to 720 degrees.

If you add 1 to 1,000,000, you get 1,000,001, which is more than if you multiply 1,000,000 by 1. Actually the same is true for any number less than 1.
The sides can add up to any number. The angles, however, always add up to 180o.
