Rounding is going to the nearest tens, hundreds, thousands etc., depending on the problem. Compatible numbers are numbers the work well with each other. Both of these are estimating.
Place names of numbers, from the right to the left are. Units Tens Hundreds Thousands Tens of Thousands Hundreds of Thousands Millions. So 2,200 Units is '0' Tens is '0' Hundreds is '2' Thiusands is '2'
Make sure that you add units to units, tens to tens, hundreds to hundreds, and so on. Keep the digits which represent the numbers in the correct columns before you add.

Well, isn't that a lovely little math puzzle we have here. If we have 990 tens, that means we have 99 hundreds in total. Each hundred is made up of 10 tens, so by dividing 990 by 10, we find our answer - 99 hundreds in all. Happy little numbers, just waiting to be discovered!
There is no four digit number where the ones is twice the tens, the hundreds is five less than the ones, and the thousands is the sum of the tens and hundreds. int ones, tens, hundreds, thousands; for (thousands=1; thousands<10; thousands++) { /**/ for (hundreds=0; hundreds<10; hundreds++) { /**/ /**/ for (tens=0; tens<10; tens++) { /**/ /**/ /**/ for (ones=0; ones<10; ones++) { /**/ /**/ /**/ /**/ if (ones != 2 * tens) break; /**/ /**/ /**/ /**/ if (hundreds != ones - 5) break; /**/ /**/ /**/ /**/ if (thousands != tens + hundreds) break; /**/ /**/ /**/ /**/ printf ("dd\n", thousands, hundreds, tens, ones); /**/ /**/ /**/ } /**/ /**/ } /**/ } }
