Let’s break down Day 06 Part 03: Binary Operation – CAIIC Axioms step by step. The acronym CAIIC stands for:

These are axioms (rules) used to describe binary operations on a set, such as addition, multiplication, etc.


What is a Binary Operation?

A binary operation on a set is a rule for combining any two elements of the set to form another element in the same set.

Notation: If ∗* is a binary operation on a set SS, then

∀a,b∈S,a∗b∈S\forall a, b \in S, \quad a * b \in S


C – Closure Axiom


A – Associative Axiom

(a * b) * c = a * (b * c)
]


I – Identity Axiom

a∗e=e∗a=a,∀a∈Sa * e = e * a = a, \quad \forall a \in S


I – Inverse Axiom

a∗b=b∗a=e(identity element)a * b = b * a = e \quad \text{(identity element)}


C – Commutative Axiom

a∗b=b∗aa * b = b * a


Summary Table:

Axiom Meaning Example (Addition on Z\mathbb{Z})
Closure Result is still in the set 3+4=7∈Z3 + 4 = 7 \in \mathbb{Z}
Associative Grouping doesn’t matter (1+2)+3=1+(2+3)(1+2)+3 = 1+(2+3)
Identity Exists an element ee a+0=aa + 0 = a
Inverse Exists an element to undo op a+(−a)=0a + (-a) = 0
Commutative Order doesn’t matter a+b=b+aa + b = b + a

If you’d like examples for multiplication, matrix operations, or modular arithmetic, I can include those too!
