@ Akash

You will have to determine which instruction belongs to which grid and then apply that instruction and solve....

@ GOtroch

I had a quick question on Outside Killer. Will the consectuive cells be marked in the puzzle or we have to find out which are the cells?? and do the consecutive numbers have to be in one single stretch or it can be different cells. For example if the outside number is 10 then can we have the grid as 1,2,5,3,4 where 1 and 2 are consecutive and so are 3 and 4. These four numbers add to 10 but are separated by a 5 in between. So is this scenario allowed or all the consecutive numbers have to be together??

On the no operations mathdoku, is there any example we can look at? Maybe some variation on Fed??

Sorry, there should be neighboring cells

5 Outside Killer
Numbers outside the rows/columns indicates that there is at least one couple of NEIGBORING cells in that row/column which sum is equal to this number

So, for example, if there is number 16 outside one row, then there have to be digits 7 and 9 as neighbors in that row

Yes, there is No Operations Mathdoku on the FED site created by oddest http://www.fed-sudoku.eu/sudokuplay/0177.swf
Also I think there are some examples on Snyder's blog http://www.stanford.edu/~tsnyder/kenken.htm

Thanks Gotroch... One last question... Can there be more than one instance of such sums...

For example 10 is outisde... I can have 4 and 6 as one adjoining pair and also 3 & 7 again in the same row?

i think it is clear in the instruction " at least one couple of consecutive cells in that row/column which sum is equal to this number"

so you can 4&6 as one adjoining pair, and also 3&7 as another in the same row/column

No, cells will not be marked.
Because If I mark all these cells, then puzzle becomes standard killer sudoku. :)

@ Gotroch
Pan Digital: Apply standard sudoku rules for the digits 1 to 9. For each group of shaded areas use this
rule: First two rows of add up to the number formed on the third row. In these areas
numbers can be repeated.

What does the last line mean..............In these areas
numbers can be repeated.
Since if the numbers are repeated then the standard sudoku rules do not apply............please clarify

They can't be repeated in the booklet example, as the shaded 3x3 areas in example perfetcly cover standard sudoku 3x3 boxes.
In competetive puzzle, placement of these areas will be different so it will allow repeating of digits.

I have checked the example and it is OK, so you probably made some mistake somewhere.
Check attached solution:
