More Dicey Operations Ayah

I first tried to to do 66 x 7 as I knew that my answer that would be the closest would still be a few hundreds away from the target of 100. That got me 462, so to make it lower I did 67 x 6, which got me 402. I then submitted it for I knew that there was no combination of 6,6, and 7 that can get lower than 67 x 6. So I submitted.
