I was doing this question of boolean algebra, Simplify f=Σ(8,12,13,14)+dΣ(3,7,9,10) using karnaugh map.. can anyone please tell me what is d in this question? I know its a stupid question but i couldn’t find it on google. And please tell me what this question means? i mean like straight away simplifying without the d expression is okay but what does the d expression signify in here ?

d stands for ‘don’t care’. Cells 3,7,8,10 do not affect the value of F.
This helps because you might be able to get a simpler expression if you ignore those cells.
