Maths Game: Cross number 2. 2-digit subtraction.

The second in our mini series of cross numbers. That’s a crossword, but with numbers rather than words as clues and answers. This one is all about subtraction of two 2-digit numbers, without crossing the tens boundary. Just slide the numbers onto the grid. There are only just enough of each digit to complete the grid correctly.
