The logical expressions are
- (X NOR Y ) OR Z ⇒  
- (A NAND B) AND NOT C ⇒  
<h3>How to determine the 
logical expressions?</h3>
<u>Logical expression 1</u>
X and Y are linked by the NOR gate.
So, we have:
X NOR Y
The X NOR Y is linked to Z by the OR gate.
So, we have:
(X NOR Y) OR Z
Hence, the logical expression is (X NOR Y ) OR Z ⇒ 
<u>Logical expression 2</u>
A and B are linked by the NAND gate.
So, we have:
A NAND B
The A NAND B is linked to C by the AND gate.
So, we have:
(A NAND B) AND C
Hence, the logical expression is (A NAND B) AND NOT C ⇒

<h3>What is the difference between group and a topic ?</h3>
<h3>Group</h3>
- You can publish a comment or question to the main community feed or to a group of which you are a member. Members with a common interest can form group within the wider community to form a small community around that topic and group posts will only appear in the feeds of other group members, not in the general community feed.
<h3>Topic</h3>
- Topic work similarly to hashtags. Use the "+" symbol to the left of the Post/Ask button to add a topic (tag) to your post or question so that it can be classified along with other related posts and topics are a way to group posts and queries with similar content, but they don’t bring everyone with the same interest together in one place and this is where the groups come in!
