Hi divya23!

The + tells us that this is an addition table - to find each entry, we sum the header entry from the corresponding row and column. For example, the first entry "inside" the table is 1, corresponding to the first row & first column, Therefore 4+x=1 so x=1-4=-3. Continue solving in this manner until you have values for m & n, then add :)
