- Axoim
- An AXIOM is a statement that we accept to be true.
- Substitution Axiom
- If two elements from a set are equal then one can replace the other at any time.
- Field Multiplication Theorem 3
- If ac=bc then a=b
- Field Multiplication Theorem 2
- If a=b then ca=cb
- Field Additive Theorem 1
- If a=b then a+c=b+c
- Field Multiplication Theorem 1
- If a=b then ac=bc
- Field Additive Theorem 3
- If a+c=b+c then a=b
- Field Additive Theorem 2
- If a=b then c+a=c+b
- Field Additive Theorem 5
- -(-a)=a
- Theorem
- a statement that can be proven through an argument. (Ex. If 2 sides of a triangle are congruent then the angles opposite those sides are congruent)
- Field Additive Theorem 4
- If c+a=c+b then a=b
- Field Multiplication Theorem 5
- (a⁻¹)⁻¹ =a, a ≠ 0
- Reflexive Axiom
- Every number or element from a set is equal to itself
- Field Multiplication Theorem 4
- If ca=cb then a=b
