Article on cost estimating?
An article on cost estimating in the building construction field, admittedly from an out dated source although the principles are still the same, is at http://www.inquirewithin.biz/Vol2/Estimating/estimating_foundations.htm.
Which is the only number which is equal to the sum of its digits?
Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.
What does estimating sums mean?

How do you estimate decimal sums and differences?
The basic idea is the same as when you estimate sums and differences of larger numbers (which may or may not be integers). You round the numbers to one or two decimal digits, then add them up.
How do you do estimating sums?
When estimating sums, it is best to round to the nearest round number. If the last place on the right is less than 5, then round down. If the last place on the right is 5 or more, then round up. For example, 43+88. You would round the 43 down to 40 and the 88 up to 90. The estimated sum would 130.
How can you estimate sums or differences of decimals?

Find your number, look Right next door, five or more just add one more, four or less just ignore...
What is an instance when you might want to find an estimate for fraction sums our differences rather than the exact answer?
