4 digit addition again!
Can you remember Roman Numerals?
(if not look at the help sheet below)
Can you find out the missing numbers?
Remember there may be some exchange happening.
Question 2 is a bit trickier, you need to set yourself up a blank 4 digit column addition and try numbers in the 10's column.
Write down the combinations of digits it could be as your answer in your book.
See help below if you need to.
In this question, the exchange happens in the 10's column
but you are being asked which 2 digits make the answer when the extra 1 from the tens column has been added.
