Real Numbers : a,b,c

  • Additive Identity : a + 0 = a
  • Additive Inverse : a+(-a)= 0
  • Commutative of Addition : a+b = b+a
  • Associative of Addition : (a+b)+c = a+(b+c)
  • Definition of subtraction : a-b = a+(-b)
  • Multiplicative Identity : a x 1= a
  • Multiplicative Inverse : a x (1/a)=1, a≠0
  • Multiplication times 0 : a x 0 =0
  • Commutative of Multiplication : a x b = b x a
  • Associative of Multiplication : (a.b).c = a.(b.c)
  • Distributive Law : a.(b+c)= ab + ac
  • Definition of Division : (a/b) = a x (1/b)
