To solve the problem of subtracting from , we'll perform vertical subtraction using step-by-step borrowing:
Let's set up the subtraction:
Write the numbers vertically aligning them by place value:
We start subtracting from the rightmost column (units):
Units:
Tens: We need to subtract from :
Hundreds: , so borrow from the thousands place:
The number becomes in thousands place and hundreds place becomes .
Subtract from : .
Thousands:
The calculation results in:
Thus, the final result of the subtraction is .
Therefore, the solution to the problem is .
922
\( \begin{aligned} &15 \\ -& \\ &~~4 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
You need to borrow when the top digit is smaller than the bottom digit in any column. Like when 1 < 2 in the hundreds place, so you borrow from the thousands.
Always reduce it by 1! If you borrow from the thousands place (3), it becomes 2. The borrowed amount goes to make the hundreds place bigger.
Check that you can subtract in every column without negative results. If 1 becomes 11 in hundreds, then 11 - 2 = 9 works perfectly!
Yes! Use addition to check: 922 + 2245 should equal your original number 3167. This proves your subtraction is correct.
When borrowing from 0, you need to keep going left until you find a non-zero digit to borrow from. The 0 becomes 10, then you can borrow from it.
