Zero is tricky and is best avoided. If you're stuck with it, the GCF of zero and any other number is the other number. The GCF of zero and zero is zero.
You cannot find the least common multiple of a single number. The least common multiple of two numbers is the smallest number (not zero) that is a multiple of both
It is zero because the positive numbers go on forever as well as the negative numbers so zero in not positive nor negative.
You can't have the greatest common factor of just one number - for it to be common there needs to be at least 2 numbers.
1 is the factor that is common to all numbers.
Real numbers are composed of rational and irrational numbers. Integers are part of the group (set) of rational numbers. And the integers are composed of the counting numbers (1, 2, 3, ...) and their negative counterparts (-1, -2, -3, ...). Oh, almost forgot. There is one more integer that is neither positive or negative. It's the number zero. Zero is an integer (neither positive or negative). The smallest real number ever is zero.
The farthest number from zero is the greatest number.
Yes. It can also be negative in the numerator. Both positive and negative numbers (as well as zero) can be rational numbers. Both positive and negative numbers can be irrational numbers. Both positive and negative numbers (as well as zero) can be integers.
A number line can have both positive and negative numbers. You can put the number line in any position, but often it is represented so that numbers to the right of zero are positive, and numbers to the left of zero, negative.
There are no whole numbers that are not also counting numbers. Both terms mean the same subset of numbers: positive integers greater than zero. Some people consider zero to be a whole number but not a counting number, because you can't "count" zero.
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
Zero is a rational number, and therefore is NOT an irrational number. The definition of a rational number is any number that can be expressed as a fraction where the numerator and demoninator are both integers, and the denominator is non-zero. Irrational numbers are all real numbers that are not rational numbers. Since zero qualifies under the definition of a rational number, (0/3, for example), it therefore cannot be an irrational number.
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.
No, not necessarily. A number line can start and end wherever you need it. But if you are including both positive and negative numbers, then there needs to be a position for zero.
One or both of the numbers must be zero.
No...zero is not a natural number, natural numbers start at the number 1.
Numbers to the right of zero on a number line are positive numbers; to the left are the negative numbers.
Most numbers are a decimal number, with zero sometimes being considered and exception. Since any number can have decimals after it (if it happens to be rounded) perhaps it is. The exact number zero, however, is not. Zero denotates a lack of value as opposed to a value - such as .01.
