OA C
Is there a quick way to do this question? Obviously, you could work through the additions but I'm sure there must be a trick - can someone spot it?

m + n = ( 4 +z ) + ( y + e )
So since we have matrix, I think I can re-arrange this:
m+ n = ( 4 + y ) + ( z + e )
m + n = - 5 + 10
m + n = 5 :!:

Could you explain this:
m+ n = ( 4 + y ) + ( z + e )
m + n = - 5 + 10
I don't see where the -5 and 10 are coming from.

hi Mankey,
this is how i understand the first response to the post -
from the table:
m = 4 + z
n = e + y
therefore m + n = (4 + z) + (e + y)
since the operation is addition, re-arranging the terms will not affect the sum.
so, you can re-arrange the terms as shown below to allow you to substitute the terms with the corresponding figures from the matrix
m + n = (4 + y) + (z + e)
from the table 4 + y = -5
from the table z + e = 10
therefore
m + n = -5 + 10
m + n = 5
hope that helps..
