**DrBob222**, Monday, October 1, 2007 at 5:38pm"Rounding to the greatest place" still is confusing to me. Rounding to the tens will be 60, to the hundreds will be 100. It seems to me that to the greatest place might mean to the thousands or ten thousands or any of a number of other values picked out of a hat. I'm sorry to be so picky but I think the instructions need to be clarified. Thanks for using Jiskha.

Rounding 21 to 20 and 34 to 35. 20 + 35 = 55
