15 638 can be made with 1 ten, 5 ones, 6 hundreds, 3 tens, and 8 ones; 1 ten, 8 ones, 6 hundreds, 3 tens, and 5 ones; or 6 ones, 5 hundreds, 3 tens, 8 ones, and 1 ten.
In 5420, you have:5 x thousand; 4 x hundred; 2 x tens; zero x ones (the American ones in math is known as units in British maths!).
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); /**/ /**/ /**/ } /**/ /**/ } /**/ } }

ones 5 hundreds is 7 hundreds, thanks now, bye
700 ones = 7 hundreds
Well, isn't that a happy little question! In 564, there are 5 hundreds. Each digit's place value tells us how many hundreds, tens, and ones there are. So, in this case, the 5 in the hundreds place tells us there are 5 hundreds in 564.
254 - has 2 hundreds, 5 tens, and 4 ones
