Round numbers to a specified level of precision, including both decimal places and significant figures. For example, express 5764 rounded to the nearest thousand. Make estimations for calculations that involve numbers, quantities, and measurements, such as estimating the value of 41.3 by rounding each number to 1 significant figure. Round results to an appropriate level of accuracy based on the context of the problem, like rounding 9.79 and 0.765.
