Dicey Operations Sam

My strategy is getting the hundreds to a value of 800 ,900 ,1000 because tells me what I need to add up to in the tens then the ones. It is hard if you get just high or just small numbers or just even or just odd because it is hard to make different numbers. The closest I got was 1 away because I got a mix of small, high, even, and odd. I decide where to put my digits by trying to make them add up 9 10 8 in the hundred then 10 to 20 to nothing. Then low ones.
