I know the answer but i don't understand the borrowing of the 2in the thousands place why is it 11 and not 12... the problem is 612,014-323,440=288,574

-----------
4 - 0 = 4
4 - 11 = 7 (borrow 1 from 0 but it doesn't have one to borrow so we must borrow from the 2 which makes that a 1 and the 0 becomes 10 and we borrowed 1 to make it 9.
9 - 4 = 5.
11 - 3 = 8
10 - 2 = 8
5 - 3 = 2
I see I goofed. Correction in one line below in bold

4 - 11 = 7 (borrow 1 from 0 but it doesn't have one to borrow so we must borrow from the 2 which makes that a 1 and the 0 becomes 10 and we borrowed 1 to make it 9. This step should be 11 - 4 = 7
9 - 4 = 5.
11 - 3 = 8
10 - 2 = 8
5 - 3 = 2

To understand why the borrowing in the thousands place is 11 and not 12 in the given subtraction problem, let's break it down step by step:
1. Start by subtracting the units place: 4 - 0 = 4.
2. Now let's subtract the tens place. Here, we encounter borrowing. We need to subtract 11 from 4.
To borrow from the two in the thousands place, we need to understand the concept of regrouping.
When there are not enough digits to subtract from in a particular place value, we need to borrow from the next higher place value. In this case, we need to borrow from the two in the thousands place.
To do this, we decrease the two by 1, making it a one, and add 10 to the zero in the hundreds place, making it 10.
So, we now have 10 in the tens place and 1 in the thousands place.
Now we proceed to subtract 11 from 4: 11 - 4 = 7.
3. Next, subtract the hundreds place. 9 - 4 = 5.
4. Subtract the thousands place. We have already borrowed from the thousands place in the previous step, so we can do a straightforward subtraction: 11 - 3 = 8.
5. Finally, subtract the ten thousands place and the hundred thousands place. Here, we again have straightforward subtraction: 10 - 2 = 8 and 5 - 3 = 2.
So the final result of the subtraction is 288,574.
