What is boolean alegbra?

Answer 1

boolean algebra is a type of algebra which only uses two numbers 0 and 1 (true and false) it only has two operations "and":* and "or":+

a+b=1 if a=1 or b=1

a+b=0 if a=0 and b=0

a*b=0 if a=0 or b=0

a*b=1 if a=1 and b=1

also a line above a variable means "not".

(not)a=1 if a=0

(not)a=0 if a=1

one of the great things about boolean algebra is that almost any equation can be solved by testing since each variable can only take one of the two values.
