A = {Tesco, Asda}

B = {Lidl, M&S, Asda}

C = {Coop, Asda, Lidl}

and the equations are like .......

Workforce \ B

&

(Workforce \ C) \ A

The problem is the only time I have ever seen a symbol like \ in maths was a divide symbol but I am taking a wild stab in the dark and going to say that it isnt divide in this situation. So any help would be really helpful too me

Thanks in Advance,
