True · 63 is only 3 steps from 60 but 7 steps from 70.
50 · 47 is closer to 50 than to 40.
4370 · 4,367 is closer to 4,370 than to 4,360.
20 · 23 is only 3 away from 20, but 7 away from 30, so it rounds down to 20.
6,000 · 3,180 rounds down to 3,000 and 2,900 rounds up to 3,000, so the estimate is 3,000 + 3,000 = 6,000.
200 · 240 is nearer to 200 than to 300.
False · 780 is only 20 steps from 800, but 80 steps from 700.
4000 · 4,367 is closer to 4,000 than to 5,000.
4,000 · Rounding both numbers to the nearest 1000 and adding gives a quick estimate of 4,000.
He rounded down when the ones digit meant round up · The ones digit is 7, which is 5 or more, so Ben should have rounded up to 4,370, not down to 4,360.
