Is every positive integer the sum of two distinct positive odd integers?

No. You can't derive 2 or any odd number from the sum of 2 positive odd integers. You can't get 2 because you would be forced to add 1 with 1. Which isn't distinct, and you can't get an odd number at all since both the other numbers are odd. Say the first one is of the form 2n+1 and the second is 2m+1. (2n+1)+(2m+1)=2n+2m+2=2(m+n+1) which has to be even.

Is every integer a natural?
No, but every natural is an integer. Only the positive integers and 0 are natural numbers.
Are irrational numbers negative integers?
No. Every integer, whether negative or positive, is rational.
Every negative number is an integer?
No, not every negative number is an integer. For example, -11/2 is not an integer. However, -1, -2, -3, and so on, are negative integers. Perhaps that is what you meant to ask. The negative of every positive integer is a negative integer.
What is the sum of the first hundred positive odd integers subtracted from sum of the first hundred positive even integer?
Should be 50! Every odd integer is 1 less than the corresponding even integer and there are 50 of each in 100...
Is it true that every integer is a whole number?
No, but every whole is a integer. integers are - and +. whole number are only +.
Is every integer a natural?
No, but every natural is an integer. Only the positive integers and 0 are natural numbers.
Are irrational numbers negative integers?
No. Every integer, whether negative or positive, is rational.
Is every number greater than zero a positive integer?
No. Only the whole numbers greater than zero are positive integers. 1, 2, 4, 989, 589595, 1000000 are positive integers. 0.5, pi, 1.99, 1000.0001 are positive numbers but they are not positive integers. 0 is an integer, but it is neither positive nor negative.
Is every integer a real number?
Yes, all integers are considered to be real numbers.
Every negative number is an integer?
No, not every negative number is an integer. For example, -11/2 is not an integer. However, -1, -2, -3, and so on, are negative integers. Perhaps that is what you meant to ask. The negative of every positive integer is a negative integer.
What is the sum of the first hundred positive odd integers subtracted from sum of the first hundred positive even integer?
Should be 50! Every odd integer is 1 less than the corresponding even integer and there are 50 of each in 100...
Why isn't every integer a whole number?
Integers can be positive, zero or negative. Whole numbers can only be zero or positive. All negative integers are not whole numbers, though they are the additive inverse of a whole number.
Is it true that every integer is a whole number?
No, but every whole is a integer. integers are - and +. whole number are only +.
What is an integers and non integers?
every whole number is an integer. any fractions or decimals like, 1/2 or .5 is NOT an integer. 6 or -341 IS an integer.
Is every whol number an integer?
Yes, but not every integer is a whole number. (Negative integers are not whole numbers.)
Is the cardinality of an infinitely countable set the same as the rational numbers?
Yes. There is an injective function from rational numbers to positive rational numbers*. Every positive rational number can be written in lowest terms as a/b, so there is an injective function from positive rationals to pairs of positive integers. The function f(a,b) = a^2 + 2ab + b^2 + a + 3b maps maps every pair of positive integers (a,b) to a unique integer. So there is an injective function from rationals to integers. Since every integer is rational, the identity function is an injective function from integers to rationals. Then By the Cantor-Schroder-Bernstein theorem, there is a bijective function from rationals to integers, so the rationals are countably infinite. *This is left as an exercise for the reader.
What integers are rational numbers?
Every integer is a rational number!
