To solve the problem, follow these steps:
Let's subtract 290 from 980 as follows:
Begin with the rightmost digits (units place):
Move to the next column (tens place):
Since is less than , we must borrow 1 from the hundreds place. The 8 becomes 18, and the result is:
Finally, move to the last column (hundreds place):
After borrowing, the hundreds column had one subtracted, changing it from 9 to 8:
Thus, the subtraction is completed as follows:
Therefore, the solution to the problem is .
Solve the exercise using the structure table below:
\( 5896+1256= \)
You cannot subtract a larger digit from a smaller digit in basic arithmetic. When 8 < 9, you must borrow from the next column to make it work!
When you borrow 1 from a digit, that digit decreases by 1. So if you borrow from 9, it becomes 8. Don't forget this step!
Borrow whenever the top digit is smaller than the bottom digit in any column. Look at each column from right to left and borrow as needed.
Yes! Add your answer to the number you subtracted. If you get the original number back, your subtraction is correct: ✓
When borrowing from 0, you need to keep borrowing left until you find a non-zero digit. Each 0 becomes 9, and the non-zero digit decreases by 1.
You could use mental math tricks like: , but the standard algorithm with borrowing is most reliable!
