can anyone help this 6 grader.?

Question

my mom cant explain this can you tell me like if you subtract the number and you borrow say the number is a nine what does it become a zero.

Answer 1

h I am going to try. First of all it is necessary to understand what a number stands for. Let's take 358. The digit 8 stands for 8 ones, or 8 times 1. The digit 5 however stands for 5 tens, or 5 times 10.
The digit 3 stands for 3 hundreds or 3 times 100. What I am trying to show you here is that each digit's place as you move to the left is
TEN times the place to its right. Therefore if you are borrowing, what you are borrowing is ten to add to the digit you need to subtract from.


Let's look at an example. 947
-65 1

So you start at the right and you subtract 7-1 and get 6
Now you go to 4-5, but now you want to borrow so you take 1 from the 9 (but this is actually 10 not 1) so adding 10 and 4 you get 14 and you can subtract 14 -5. Now on to the 9. since you know how I will leave it to you. Hope this helps, if not ask again

Answer 2

If it's a 9 and you borrow, it becomes an 8.

If it's a 0, you borrow from the number to the left of it, you're borrowing 10, so 1 from 10 leaves 9.

Answer 3

When you borrow you are taking a bundle of 10.... like
say 20 take away 19
if your ones column is 0 the number to the left is the 10s column you borrow a bundle of 10 .. .. add the 10 to the zero making it 10 that way you can take it from 9..
the 1 you left over the 2 .. take away 1 becomes 0.
Its all about a bundle not just 1.

Answer 4

(1)Subtract the number
(2)Borrow 9
(3)It becomes a zero
