I know the basics of borrowing when subtracting, but here is when I get stuck. I am subtracting two three digit numbers. 771-252. The 1 becomes an 11, 11-2=9 bring the 7 in the tens column to a 6, 6-5=1. Now I don't bring the 7 in the hundreds column down to a 6. Why is that? In 916-618, the 6 becomes a 16, the 1 is brought down to a zero and becomes a 10, and the 9 is brought down to an 8. Why must all the numbers in 916 be regrouped but not all in 771? </SPAN>\n" );
