Subtracting Across Zeros Fourth Grade

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. 704 - 438 But what happens when the next door neighbor is the number zero?

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

How can I borrow when the neighbor is a zero? 704 - 438 When the next door neighbor is a zero, you can’t borrow from it. So, you must continue to the next neighbor to see if you can borrow from it.

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.

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

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

We can go back now to the tens place and borrow from our neighbor the ten. 10 6 704 - 438

First we borrow from the ten and make it a nine. 9 10 6 704 - 438

Then we change the four to a fourteen. 9 10 14 6 704 - 438

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

9 10 14 6 704 - 438 2 6 6

How can I borrow when the neighbor is a zero? 300 - 266

Six cannot be subtracted from zero so we have to go to the next door neighbor to borrow. 300 - 266

When the next door neighbor is a zero, you can’t borrow from it When the next door neighbor is a zero, you can’t borrow from it. So, you must continue to the next neighbor to see if you can borrow from it. 300 - 266 In this problem, the next neighbor is the number three. We are able to borrow from this neighbor.

First you borrow from the three and make it a two First you borrow from the three and make it a two. Then you can go back to the zero and make it a ten. 10 2 300 - 266

We no longer have a zero, but we still are not able to subtract six from zero. 10 2 300 - 266

We can go back now to the tens place and borrow from our neighbor the ten. 10 2 300 - 266

First we borrow from the ten and make it a nine. 9 10 2 300 - 266

Then we change the zero to a ten. 9 10 10 2 300 - 266

We are now ready to subtract! 9 10 10 2 300 - 266

We are now ready to subtract! 9 10 10 2 300 - 266 3 4

Now it is your turn to try one! 9 10 10 6 700 - 211 4 8 9

Try another one! 9 10 10 7 800 - 92 7 8

Try one more! 9 9 10 4 10 10 5,000 - 174 4, 8 2 6

Now you are ready to try some on your own good luck!
