Question

What is `387.04-128.8`?

Answer 1

258.24

Explanation:

Just subtract how you usually would!

387.04 - 128.8

ALWAYS start subtracting from the end.

You can automatically bring the four down as the hundreths place because there isn't any number being subtracted from it.

Since 0 can't technically be subtracted by 8 ( at least not in this type of subtraction) you would borrow from the next number over, which, in this case, would be 7.

0 would turn into 10 and you would subtract 8 from 10.

You would follow the same process for the next number over and get 8, just remember that since you borrowed from that number, it will be one number less, ( 16 instead of 17)

Again, remember that you borrowed from the number, and you will get a 5.

After this, you subtract normally.

You should have gotten 258.24.

Hope this helped~
