That's a bad idea. You should code it as

my sum = 100 * 101 / 2;
[download]

or something like that.

I know this from practice, as I once accidentally wrote 8092 instead of 32*256 in a program and had a hard time finding out why it wouldn't work. A computer can do arithmetic better than any of us.

I did it with a computer...in the shape of a calculator:)

I get your point, but unless the constants 100, 101 and 2 have some meaning in context, you've just advocated magic numbers.

A well named constant, that made sense in context, would be preferable.
