This follows from the way in which addition of whole numbers is defined.
There are no four consecutive whole numbers that add up to 35. The sum of two consecutive [whole] numbers is an even number plus an odd number which is an odd number. The sum of two consecutive numbers and the two next consecutive numbers is the sum of two odd numbers which is even, but 35 is odd, so no four consecutive whole numbers cannot add up to 35.
2 mixed numbers can only be a whole when the 2 numerators add up to the number
When you add two or more prime numbers you will only end up with a whole number and not a decimal number.
The sum of two numbers is a whole number if both of the numbers are whole numbers, or if the sum of two fractions can be simplified to a whole number.
No, it is not, because whole numbers must be positive.
Yes, any two whole numbers added together will equal a whole number.
If the two numbers are both whole numbers then yes
44
Yes, the product of two whole numbers is a whole number. For example 3*7 = 21
The product of two nonzero whole numbers will be a nonzero whole number.
No. You can subtract two whole numbers and get a negative result. Whole numbers can't be negative.
Yes, the difference of two whole numbers is always a whole number.
