Everyone is following the directions, BUT to minimize round-off error it is best to complete all operations carrying all decimal places and round at the end. Here you get the same answer but that is not always the case.

a = 43.941, b = 35.54;

ar = a rounded to nearest whole number = 44;

br = b rounded to nearest whole number = 36;

Estimated sum = ar+br = 80.

Estimate 44 + 36 = 80

35.54 is rounded to 36.

Reason: 100 - 54 = 46, 54 -54 = 0

46 is closer to 100 than it is to 0.
