Explain why the sum of three consecutive integers is divisible by three?
Here are some consecutive odd integers. All must follow this form: x+x+2+x+2=3x + 6 6 is divisible by 3. So is 3x. If you add two integers that are divisible by 3, it is still divisible by three. The question is not about odd integers, but consecutive integers. This should be x + x+1 + x+2 =3x+3 A bit simpler would be the three in a row : x-1, x, x+1 which add up to 3x which can be divided by 3.
How do you add and subbtract positive and negative integers?
When adding negative integers, you subtract. (2+-1=1) When subtracting negative integers, you add. (2--3=5)
Is this statement true if the product of two integers is divisible by 6 one of the integers is also divisible by 6?
That is false. This type of statement is only true for prime numbers, not for compound numbers such as 6. Counterexample: 2 x 3 = 6

What is the whole number that is not divisible by 2?
All odd whole numbers are not divisible by 2.The term "whole number" has three distinct definitions, in my experience.- Positive Integers ( 1, 2, 3, ... )- Non-Negative Integers ( 0, 1, 2, 3, ... )- Integers ( ..., -3, -2, -1, 0, 1, 2, 3, ... )The largest whole number that is not divisible by two would be the largest odd number, which is not defined.The smallest Positive Integer which is not divisible by two would be 1.The smallest Non-Negative Integer which is not divisible by two would be 0.The smallest Integer which is not divisible by two would be the most negative odd number, which is not defined.
Is the statement 14n -1 is divisible by 13 true for all positive integers?
No. It's not true for n=2, where 14n - 1 = 28 - 1 = 27, which is not

How many odd integers under 1000 are not divisible by 5?
you can say that 2/10 of every 10 integers is divisible by 5, so multiplying 2/10 by 100, giving you 200/1000 total integers are divisible by 5. half of all integers are odd, so divide 200/1000 by 2 is 100/1000, so you can correctly state that 100 odd integers under 1000 are divisible by 5.
