Do you round both numbers of estimating?
Yes but, if you can, you should try to round one up and the other down. Unless that results in rounding well away from the number. For example, 48*62 Exact answer = 2976 If you round 48 up to 50, 62 down to 60 Estimate = 50*60 = 3000 (estimation error = +0.8%) But if you had 48*68 Exact answer = 3264 Round up and down: 50*60 = 3000 (estimation error = -8.1% ) Round down and up: 40*70 = 2800 (estimation error= -14.2%) Round up and up: 50*70 = 3500 (estimation error = +7.2%) The last still has a large error but it is the smallest of the these.

What is the greatest number to round off 3000?
Assuming whole numbers: If rounding to the nearest 10, it would be 3004 If rounding to the nearest 50, it would be 3024 As "to the nearest whatever" increases, so the greatest number also increases. So the greatest "whatever to round to" to produce 3000 must be 3000, that is the question becomes: What is the greatest number that rounds to 3000 to the nearest 3000? Half of 3000 is 1500, so the greatest whole number that rounds to 3000 is 3000 + 1500 - 1 = 4499 (since 3000 + 1500 = 4500 would round up to 6000). Any number such that 1500 ≤ number < 4500 will round to 3000 to the nearest 3000.
