How do you estimate sums and differences of whole numbers and decimals?
decimals must be estimates unless they have multiples of 2 or 5 in the mantissa 1.857142857 + 2.142857142 =3.9999999999 estimate 4.00000000 1 6/7 + 2 1/7 = 4 exact 1.1250000000 + 2.875 = 4.000 +- only 3 significant digits so best estimate possible 1 1/8 + 2 7/8 = 4 exact
