Approximations
Info About Approximations
People estimate unknown values using clues they already have. That habit cuts down on detailed work with decimals or whole numbers. It keeps math moving without halting for extra steps. This practice appears in fields like finance, science and engineering.
A popular tactic trims numbers down to friendlier size. Rounding pushes decimals toward the nearest whole digit. It turns 3.7 into 4 and 6.2 into 6. Other tricks chop off extras or swap curves for straight lines. Each choice trades a bit of precision for a faster result.
Many problems demand long calculations and each step eats time. Rough guesses beat exact totals in those moments. A close estimate lands near the real value without fuss. Time limits and missing data push teams toward that choice.
