Front end estimation generally produces a better estimate of sums or differences than rounding before adding or subtracting. How to Estimate a sum by front end estimation * Add the digits of the two highest place values * Insert zeros for the other place values * Example 1: 4496 + 3745 is estimated to be 8100 by front end estimation (i.e. 4400 + 3700). * Example 2: 4496 + 745 is estimated to be 5100 by front end estimation (i.e. 4400 + 700).
Area= pi × radius2 Area= 3.14 × (4.5 in2) Area= 3.14 × 20.25 Area= 63.585 in2 The answer is 63.585. You would find this answer by doing this: 20.25 x3.14 _______ 8100 20250 +607500 _______ 635850 Then you would take the zero off the end.
