Hello Fig,

Problem area for me is with med/difficult mixture problems, which unfortunate come in a variety of ways.

MGMAT provided useful insights, PR little to none. . .

I was wondering if there are any notes out there that deal with the logical assumptions that can be drawn from algerbraic expressions: Short cut to testing numbers.

For example:

if b/a = even then b must be even

or

if a, b, c are integers and (a-b)c = odd then a and b are not the same: 1 odd and 1 even

Are there any notes out there that have made these kind deductions. I am hoping to supplement my practical ability to test numbers, and I'm lazy.

Thanks pal,
