While many condemn this "new math" because it doesn't require precise answers, most decisions in life that involve math only require that you recognize the best option. Estimates are good enough

If you go to McDonalds with $20 and order six items you make an estimate of whether $20 is enough money, you don't calculate that you will get 17 cents in change
