Answer:
68719476736
Step-by-step explanation:
I think I can give you the answer, but I don't think I can explain it very well.
It looks like you are starting out at 2 and progressing to 3. The problem is that the answer has a minus sign after the two.
What I am assuming is that you know what a minus number is and what you do when 2 of them are in a row. If you do, then you should write
2 - -1 = 3
The first box contains -1 and the second box contains 3.

Answer:
The 2 digit number is 36.
Step-by-step explanation:
Let the 2 digits be x and y . The 2 digit number is xy.
x + y = 9........(1)
The old number can be written as 10x + y and the new number as 10y + x.
10y + x = 10x + y + 27
9x - 9y = - 27
x - y = -3 ......(2)
Adding (1) and (2) we get:
2x = 6
x = 3
and therefore y = 9-3 = 6.
