Default How do I write formula to conditional format using =if(and(or)

try

I need to compare the values in two cells, A1 and B1, I wish to put the
conditional formating on cell b1.

I need to determine if A1<0 and B10 or if A10 and B1<0.

If either of these two conditions occur, I need the cell of b1 to turn yellow.

I have tried using =if(and(a1<0,b10), =if(or(and(a10,b1<0), ???????

Any assistance would be appreciated.

Thanks! Don
