/: I am at home.
Masja [62]
This is a Logic Problem. So we need to use operators to solve this problem. There are several operators in logic. Operators can be <em>monadic</em> or <em>dyadic</em>. A monadic operator operates on a single simple statement. Other operators will all be dyadic operators <span>because they operate on two simple statements. So in this problem we have the following operators:
</span>
1. The negation operator:

<u>Symbol:</u> ~
<u>Symbol name:</u> Tilde
<u>Parts of negation</u><span><u>:</u> A simple statement with a tilde preceding it</span>

2. Conjunction:

<u>Symbol:</u> &
<u>Symbol name:</u> Ampersand
<u>Parts of conjunction:</u> <span>Two simple statements joined by the conjunction symbol. 
</span>
So we can name the statements as follows:

A: I am at home
B: I am playing video games

So the translations is as follows:

~(A&B) = It is not the case that I am at home and am playing video games
