Commutative

Bit like commuting on a train. You move from one place to another

Compare the process given in the question to the following example:

#2+3 =5#

You get exactly the same answer as #3+2=5#

They have moved.

A very important one is that of multiplication.

#2xx3=6# has exactly the same answer as #3xx2=6# However there are traps in multiplication and division. You must be very careful.

Another very important example:

Suppose I had #10-16=-6#

#color(brown)("The minus follows the 16 and the plus follows the 10 so you would write")# #-16+10=-6#
