Transitive= If a=b and b=c, then a=c
Reflexive= a=a
Symmetric= If a=b, then b=a
Substitution= If a=b, then b can replace a in any expression

# data[].attributes.body
Addition = If a=b, then a+c=b+c
Subtraction=If a=b ,then a-c = b-c
Multiplication=if a=c, then a x c= b x c
Division= If a=b, then and c doesn't = 0, then a/c= b/c

Use multiplication to distribute a to each side of the sum or difference within the parentheses
a(b+c)= ab+av

If p--q is true
and q--r is true,
then p--r is true.
