What does each zero in the multiplier indicate when multiplying by 10, 100, or 1000?

When multiplying a number by 10, 100, or 1000, each zero in the multiplier indicates a shift of the decimal point to the right. This shift corresponds to increasing the value of the original number by a factor of ten for each zero present. For example, if you multiply 5 by 100, which has two zeros, you effectively move the decimal point in 5 (which is 5.0) two places to the right, resulting in 500.

This concept is crucial in understanding how multiplication by powers of ten affects numeric values, reinforcing the notion that each additional zero represents a tenfold increase in size. As a result, multiplying by these values increases the original number rather than decreasing it or not affecting it at all. Thus, the correct answer reflects the foundational principle of place value in our number system, emphasizing how multiples of ten influence decimal placement and overall magnitude.
