I have a question about applying the rules of significant figures to calculations. Should one apply the rules to everyday calculations? I don't know if it will benefit me in the long run to count the number of sig/decimal places in numbers in the simplest calculations. If I major in engineering/physics/math, will I need to use sig figures everyday of my life or what? Do you need to use significant figures in chemistry? physics? everything related to math and calculations? thanks.(adsbygoogle = window.adsbygoogle || []).push({});
