Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
odd * odd = odd answer even * even = even answer odd * even = even answer
Yes. Even + Even = Even, Odd + Odd = Even and Even + Odd or Odd + Even = Odd
even times even = even odd times odd = odd even times odd = even

You cannot. The sum of any two odd numbers is even (O+O=E), the sum of any two even numbers is even (E+E=E) and the sum of an odd and an even (or even and odd) is odd (O+E=E+O=O). O+O+O+O+O = O+O+O+O+O = E + E +O = E +O = O Addition is commutative, that is, the order in which you add the numbers does not matter. Some trial and error will demonstrate commutativity, though a proof is more complicated.

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 0 is an even number.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 93 is an odd number.
It will be Odd if the original number was Odd - you have O + O + O = (O + O) + O = E + O = O Otherwise it will be Even if the original number was Even - you have E + E + E = (E + E) + E = E + E = E ------------------------------ Algebraically: For an odd number x = 2n + 1 where n is an integer 3x = 3 × (2n + 1) = 6n + 3 = 6n + 2 + 1 = 2(3n + 1) + 1 = 2m + 1 where m = 3n + 1 which is an odd number For an even number x = 2n where n is an integer 3x = 3 × 2n = 6n = 2(3n) = 2m where m = 3n which is an even number
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
odd * odd = odd answer even * even = even answer odd * even = even answer
even times even = even odd times even = even odd times odd = odd
Yes. Even + Even = Even, Odd + Odd = Even and Even + Odd or Odd + Even = Odd
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
Always. even + even = even odd + odd = even even + odd = odd odd + even = odd To summarise, if you add like numbers you get even, otherwise you get odd.
even times even = even odd times even = even odd times odd = odd
