Question

Explain how to subtract 247 from538

Answer 1

 538
-247
( 8-7 is 1, you borrow from the 5 so 3 becomes 13 - 4 which is 9, and since you borrowed from the 5, five becomes 4 and 4 - 2 = 2)

The answer is 291.

Answer 2

Remember you are taking 247 from 538, so we write the big number on top, and the small one on the bottom and we subtract like this:

       538
   -   247
 ------------
       291

And you get 291.
