Final answer:
Rounding to the nearest thousandth involves analyzing the digit in the thousandths place and using rules of rounding to adjust the number appropriately. Examples provided demonstrate the rounding of a calculator answer to align with the least precise digit in the calculation. Basic knowledge of integer powers is also highlighted as fundamental in understanding rounding and decimal representation.
Step-by-step explanation:
When rounding numbers to the nearest thousandth, it's essential to look at the digit in the thousandths place and determine whether it is greater than or equal to five to round up. The provided information indicates various examples where numbers are being rounded, mostly to the hundredths place based on the precision of the given values.
For instance, a calculator answer of 921.996 is rounded to 922.00 because the digit in the thousandths place (6) is greater than 5. Another example given is 201.867 being rounded to 201.87. These examples demonstrate the concept of rounding linked to the least precise measurement in a sum.
The basics of working with integer powers are also covered, illustrating that 10³ equals 1,000 and 10^-4 equals 0.0001. This foundational knowledge is used to understand rounding and representing numbers in decimal form.
