# Proving Boolean functions watch

1. I have to use Boolean Algebra to show some functions are true. Does this mean truth tables and K-maps should be used in order to show they are true as im not sure how else i could do it?

If you have to use Boolean Algebra, then no, truth tables and K-maps are not the way to go.

Presumably you've been taught what Boolean Algebra is, and should have something in your notes. If they don't make sense, then Google, or if you have a specific question, you can always ask here.

PS: If you have a further question, it would help to know what symbolism you're using for Boolean Algebra - to represent the operations.

Thanks for reply. What I intend to do is show a truth table in the results section and then use the discussion to explain why the function is true in terms of rules of boolean multiplication and addition etc, using the truth table to support my explanation
