Logical Connectives (Part 1) - Logical Reasoning Video Lecture | UPSC Prelims Paper 2 CSAT - Quant, Verbal & Decision Making

hello everyone this video has been
brought to you by an academy my name is
mouth Gupta and in this video I will be
talking about logical connectives so
before we jump on to the topic the main
topic of logical connectives we must
learn what is a statement okay so what
is a statement a statement is a
declarative sentence declarative
sentence that can be either true or
false so that is the simple definition
of a statement statements are built from
simple statements using logical
connectives okay so what are logical
connectives there are various type of
logical connectives such as this symbol
that means negation this symbol that
means and this means or this means
conditional
this means by conditional so these are
various connectives that make a
statement so let us see an example if I
want to express P or not Q by a
statement I will write it as P or Q
negation okay if I want to write F P and
R then Q so I will write it as P and R
then Q okay if I want to write either P
or Q either P or Q so I will simply
write P or Q if I want to write P but Q
then I will write P this the symbol in Q
if I want to write P if and only if Q
and R then I will write P if and only if
bidirectional Q and R let us see one
more if I want to write P is equivalent
to Q P is equivalent to Q or Q is
equivalent to P then I will write P
bidirectional Q so these are some
examples of what are logical connectives
