Say I have this: $\displaystyle \overline{(A+B)(A`+B`)}$ Can I smash up those parentheses in the middle there? To make it: $\displaystyle \overline{A+B} + \overline{A`+B`}$ Like is it basically just a multiplication sign? Or are there  consequences to the fact it should have been distributed?

It's correct. But don't think of it as multiplication and 'smashing up parentheses' (how violent! poor parentheses ). We just use regular algebraic notation to denote 'AND' and 'OR' in the Boolean world.

Lul  black holes are violent but there's a very good chance they probably created us. Smashing = violent yet creative
