Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Division by Zero

In mathematics, division by zero is undefined. This means that any expression where the divisor is zero does not yield a valid numerical result. In the case of the expression 0/-8, the divisor is -8, which is not zero, allowing for a valid division. However, if the divisor were zero, the operation would be invalid.

Zero as a Numerator

When zero is the numerator in a fraction, the result is always zero, provided the denominator is not zero. This is because zero divided by any non-zero number equals zero. In the expression 0/-8, the numerator is zero, leading to a result of zero, which is a fundamental property of division involving zero.

Negative Numbers in Division

Dividing by a negative number affects the sign of the result. When a positive number is divided by a negative number, the result is negative. In the expression 0/-8, since the denominator is negative, the result remains zero, as zero does not change sign regardless of the sign of the denominator.
