Question

prove that whole is greater than parts.

Answer 1

for ex
W=p1 +p2
where W is described as the sum of two parts p1 and p2 hence W is a whole

subtracting p1 from both the sides we get
W-p1=p2
which means if something is subtracted from W,then we get p2 which means p2 is definately smaller than W
Now subtracting p2 from both the sides we get,
W-p2=p1
similarly p1 is also smaller than W because you need to subtract something from W to get p1

Since both p1 and p2 were the parts of W they have been proven to be smaller than W and every 'whole' can be described as a sum of its parts hence all 'wholes' are bigger than their parts
