### about something called "discrete mathematics"

Hi,
I'm asking about discrete mathematics, we take this course in our studies but I didn't saw it in math is fun.com

it is about if p then q and if and only if.... and it is about True or False,...etc

can anyone tell me where can I find an introduction about discrete mathematics in math is fun?

How about you play some Games instead? I guess a lot of these games are discrete rather than continuous

Hmmm, okay, you got me. Why should he do that? I know you have a reason.

In mathematics, you don't understand things. You just get used to them.

Hi, I didn't understand what you said, can you explain your words please, I'll try to play these games later but I need to study discrete mathematics like (if and only if)

I did it in university with our techer but I need to study it from math is fun.com

#bobbym

he told us there is a relationship between discrete mathematics and computer science,

so can you help me find any website or link in math is fun.com

Hi;

I was asking Agnishom why he answered the way he did. I did not find anything under the heading of Discrete Mathematics at Mathisfun. Have you googled for something else?

hi Hannibal lecter

I think this is one area of maths that is not covered by Maths Is Fun.  It is also known as mathematical logic, propositional logic or even propositional calculus so you might find something under an alternative name.  It is the gateway to computer science because logic deals in TRUE and FALSE and computers work with binary arithmetic, 0s and 1s.  In logic we have operations like  AND, OR and NOT.  From these you can make up new operations like NAND (= NOT AND) and computer circuits are constructed out of components that behave like NAND.  For example, you can build a circuit based on NANDs that adds two binary numbers together.

It is a long time since I last did this, but I might be able to remember and I'm sure it will be good for me, so post if you have difficulties with the subject, and I'll do my best.
