Question

Kaneki can’t subtract 1000-7 because he doesn’t have enough fingers. How can he subtract correctly if he doesn’t have enough fingers?

Answer 1

There are a few ways:

You can do counting like this...

1000

999

998

997

996

995

994

993

Another better and faster way will be to do 3+990

The reason is becuase 7-10=3 and also that we can remove the 10 from 1000

So those were 2 ways how she can subtract CORRECTLY!

Have a great day!
