Answer

16,004 - 5,087 = 10,917

Work Step by Step

16,004 - 5,087 = 10,917 Subtract the ones column. Since 4 is less than 7 you must borrow. Since the tens and hundreds columns both contain zero you must first borrow from the thousands column. Compute 14 - 7 = 7. Write 7 in the ones column. Subtract the tens column, which now contains 9 because of borrowing. Compute 9 - 8 = 1. Write 1 in the tens column. Subtract the hundreds column, which now contains 9 because of borrowing. Compute 9 - 0 = 9. Write 9 in the hundreds column. Subtract the thousands column, which now has a value of 5 because of borrowing. Compute 5 - 5 = 0. Because this is not the highest order digit in you result, write 0 in the thousands column. Subtract the ten thousands column. Compute 1 - 0 = 1. Write 1 in the ten thousands column.
