When a number is tripled is it odd or even and why?
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
Would an even plus and even equal an even?
Yes it would Even + even = even Even + odd = odd Odd + odd = even
Is the sum of two odd numbers is always odd?
Remember ODD +/- ODD = EVEN Odd +/- EVEN = Odd Even +/- Odd = odd Even +/- Even = Even. Similarly. Multiplication and division. Odd X Odd = Odd ( e.g. 3 x 5 = 15) Odd X Even = Even ( e.g. 3 x 4 = 12) Even X Odd = Even ( e.g. 6 x 5 = 30) Even X even = Even ( e.g. 6 x 8 = 48). Note the subtle differences between addition and Multiplication.
Why can't you get an even number when you add three odd numbers?
because... odd+odd=even even+odd=odd e.g 1+1+1=3 odd+odd+odd=odd
Why even number squared will be even?
because that's the theory of maths even x even = even even x odd = odd even + even = even even + odd = odd
Is O is odd or even?
even
How do you get by adding five odd numbers to get fourteen?
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.
Can 4 uneven numbers added together equal 15?

Is ninety three even number o odd?

When a number is tripled is it odd or even and why?
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
If you add 3 to an even number the sum would be odd or even?
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
Is even times even odd?
even times even = even odd times even = even odd times odd = odd
Does multiplying an odd number by an even number give an even answer?
odd * odd = odd answer even * even = even answer odd * even = even answer
When you add to even numbers is the answer always even?
Yes. Even + Even = Even, Odd + Odd = Even and Even + Odd or Odd + Even = Odd
Is the sum of an odd number and an even number always even?
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
What happens when you add two even numbers Will you get an even number?
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.
Is even times even?
even times even = even odd times even = even odd times odd = odd
