I don't understand how to produce a truth table for a logic gate, if anyone could help that would be great.

I'll be happy to help! Just a quick couple of questions: What level are you studying at? (GCSE or other) What logic gates are you aware of? Do you understand how logic gates work?

I am doing IGCSE and it is saying about the different logic gates and then it asks me to find out why: x = (a.b) + (a.b) or something like that but i don't understand what it means.

It might be easier to watch a video which visually shows this.

I find that a lot of the time truth tables can actually be derived so you don't have to remember them, like if you know what or gate does them you can produce the outputs from them as long as you remember it also turns on when a 1 and 1 is produced unless it is an xor gate.
