Best Answer

There are just three possible cases:

Positive integer: positive x positive = positive.

Negative integer: negative x negative = positive.

Zero: zero x zero = zero.

The sum of zero and a negative integer can never be zero - it will always be negative and nonzero. Although zero is also an integer, it is neither negative nor positive and cannot be the other integer used.

1.56 cannot be an integer, since the set of integers do not include any decimal numbers, only whole numbers, negative or positive (including 0).

You cannot get real square root of a negative number because two numbers multiplied by themselves are always positive You can always get a real cube root of a negative number because three negative numbers multiplied by themselves give a negative .

You cannot factor negative radical numbers because the square of a number must always be positive. A negative number multiplied by a negative number produces a positive number. So, it is impossible to have a negative radical.

it is a whole number, and not an integer because you cannot have a negative circumference.

Yes. eg: a fraction -4/2 = -2 an integer

By definition, a negative integer is any integer less than zero. Similarly, a positive integer is any integer greater than zero. It should be immediately obvious that an integer cannot be both less than and greater than zero. Therefore, a negative integer cannot be greater than a positive integer.

You cannot multiply "operations" together, that is meaningless. If you are referring to a positive number multiplied by a negative number, the result would be negative.

The question cannot be answered because it is based on a false premise: negative pi is NOT a negative rational number.

The product of two integers cannot be "positive and negative".

The question cannot be answered because it is based on the wrong premise that "the product of two negative integers always negative".

That number is infinite. There is no number so large that it cannot be multiplied by 11.

An unsigned integer cannot be negative. It has a maximum positive value twice that of a signed integer. Max signed: 128 Max signed: 256 I could be off by one there, though.

It is not - so the question is seriously flawed. If you stated that -1 was the greatest (most positive) negative integer you would be correct. However, numbers are infinite so you cannot state a greatest integer. Integers are both positive and negative numbers, but have to be whole numbers

1.56 cannot be an integer, since the set of integers do not include any decimal numbers, only whole numbers, negative or positive (including 0).

It means the absolute value of the integer, or its distance from 0. Since a distance cannot be negative, the absolute value is always positive.
