Subtraction Across a Zero Third Grade

3
How can I borrow when the neighbor is a zero? 704 - 438

4
How can I borrow when the neighbor is a zero? 704 - 438 Eight cannot be subtracted from four so we have to go to the next door neighbor to borrow. What happens when the next door neighbor is the number zero?

5
How can I borrow when the neighbor is a zero? 704 - 438 When the next door neighbor is the number zero, you cannot borrow from it. You must continue on to the next neighbor to see if it is possible to borrow from it.

6
How can I borrow when the neighbor is a zero? 704 - 438 In this problem the next neighbor is the number seven. We are able to borrow from this neighbor.

7
704 - 438 6 First you borrow from the number seven and make it a six. Then you can go back to the zero and make it a ten. 10

8
704 - 438 6 We no longer have a zero, but we still are not able to subtract eight from four. 10

9
704 - 438 6 We can now go back to the tens place and borrow from our number ten. First we borrow from the ten and make it a nine. Then we can change the four to a fourteen. 10 9 14

10
704 - 438 6 We are now ready to subtract! 10 9 14

11
704 - 438 6 10 9 14 6

12
704 - 438 6 10 9 14 66

13
704 - 438 6 10 9 14 662

14
Now its your turn to try one! 903 - 475

15
What answer did you get? 903 - 475 A. 572572 B. 432432 C. 428428 D. 438438
