Final answer:
The expression −100 can represent a simple numerical value of negative 100 in mathematics, scientific notation with an error, or in a physics context, a displacement of 100 meters in the negative direction.
Step-by-step explanation:
The expression −100 can be interpreted in the context of scientific notation, powers of 10, or displacement in physics. When dealing with powers of 10, moving the decimal point to the left by the number of zeros gives an equivalent expression. For example, 10² which is 100, means moving the decimal two places to the left when dividing. In this case, since there's no decimal shown in −100, it would signify a whole number −100 without further decimal adjustments. However, if the purpose was to imply scientific notation, such as using powers of 10 with a negative exponent, then −100 would not be a standard notation as negatives are typically represented in the exponent expressing division (for example as 10⁻¹).
However, if this is meant as a physics context, like in displacement, −100 m would indicate a displacement of 100 meters in the direction opposite of the one chosen as positive at the start of the problem. For example, if Komal's displacement towards the school from his house is positive, then −100 m implies moving 100 meters away from the school
