Question 197310
The  distribution  Property  is usually  stated  as  a(c+b) = ac +bc
.
the  reverse  of  this  property  is  factoring ,  which  is  what  we  did,  taking  the  5  out.
.
The  other  properties are  cummulative,  a*b = b*a
associative  (a*b)*c = a*(b*c)
inverse  ,,reciprocal  of  a  =  1/a
