Question 187446
Subtraction is NOT commutative. Here's a counter example:


{{{3-2=1}}} while {{{2-3=-1}}}


Since {{{1<>-1}}}, this means that {{{3-2<>2-3}}}. So subtraction is NOT commutative.



Multiplication is commutative (it's been proven), but division is NOT commutative



Counter Example: 


{{{10/2=5}}} while {{{2/10=1/5=0.2}}}


Since {{{5<>0.2}}}, this means that {{{10/2<>2/10}}}. So division is NOT commutative.
