Hey there!
There are reasons why subtraction is not communative. Here's an example.
5-9=-4
9-5=4
Since -4 does not equal to 4, subtraction is not communative.
Communitive property states that a+b=b+a or ab=ba. This is not true for subtraction, since a-b=-(b-a). a-b does not equal to b-a. This is also not true for division i.e. a/b does not equal to b/a.
Example.
5/4=1.25
4/5=0.8
Since 1.25 does not equal to 0.8, division is not communtative.
Hope it helps!

first of all, enable's define what it ability for an operation to be commutative: a binary operation on a sequence S, which we are going to indicate with the # image is commutative if and on condition that (a # b) = (b # a) with a and b belonging to S. To make it somewhat less demanding, enable's look at the addition of actual numbers. we've: a million + 3 = 3 + a million seventy one + ? = ? + seventy one 18/32 + 33/171 = 33/171 + 18/32 further with multiplication: 7 * 2 = 2 * 7 22 * ? = ? * 22 Now, as for an occasion, evaluate putting on a pair of pants. it is not appropriate which leg you positioned the pants on first; it might desire to be your left leg, or your top leg. yet if you positioned the two legs interior the, the tip result's which you have your pants on, and which leg went in first is beside the point.

9 - 5 = 4
5 - 9 = -4
-4 does not equal 4, so it's not commutative
9 + 5 = 14
5 + 9 = 14
14 = 14, it's commutative

hi arria,
the word commutative(in maths) means that if u process the given numbers in ant order the answer is the same.
for eg- addition is commutative: 2+3=5
3+2=5
subtraction is not commutative: 2-3=-1
3-2=1

1-2 = -1
2-1 = 1
the answers are not the same when you switch the numbers around, therefore subtraction is not commutative.

5 - 3 = 2
3 - 5 = -2.
If it were commutative answers would be the same.

Additional info:
division also is not commutative
8/4 = 2 while 4/8 = 1/2

y - z is not equal to z - y
for example 5 - 2 =3, while 2-5 = -3
