Question 225400
Lets  just  look  at  the  visual  representations
.
Addition,,,,0+0=00,,000+000=000000,,00000+00000=0000000000,, in  short  when  we  increment  an  odd  number  on  top  of  an  odd  number  ,,,it  will  be  even.
.
If  this  was  multiplication  this  would  be  an odd  number  taken  an  even number  of  times,,,(2)
.
.

.
Multiplication,,,,is  repeated  addition,,,but
.
1*1 = 0,,,,,
.
.
3*3 = 000
,,,,,,000
,,,,,,000,,,,,,,,,or  the  summation  of an  odd number  by  and  odd  number  of  sets.
.
.
5*5,,,,=,,,,00000
,,,,,,,,,,,,00000
,,,,,,,,,,,,00000
,,,,,,,,,,,,00000
,,,,,,,,,,,,00000,,,,,again an odd  number taken an  odd  number  of  times
.
.
Hopefully  this  "adds"  some  insight...  Please  review  several  times.
