Latex Problem for Set B Minus set B' that is B \ B' (SOLVED)

[Math Amateur]

Can someone show me how to include the set minus operation in latex code ... obviously there is a difficulty that the symbol \ within latex delimiters just leaves a space ...

... so [math] B \ B' [/math] doesn't result in B \ B'

(SOLVED) B \text{ \ } B' works ... ... ... ... ... [math] B \text{ \ } B' [/math]

Use the \setminus symbol: $B\setminus B'$.

Thanks Opalg
