Question

With the help of two examples each , show that

subtraction is not commutative for integers.

Answer 1

Lets take two integers as $6$ and $9$

$9-6=3$

$6-9=-3$

$9-6\ne 6-9$

Lets take $5$ and $-1$ as two other examples for integers

$$\begin{gathered} 5-(-1)=5+1=6 \\ -1-5=-(1+5)=-6 \\ 5-(-1)\ne -1-5 \end{gathered}$$

So Substraction is not commutative for integers.
