0:+15:−16?0
Let's solve the exercise from left to right:
Let's remember the formula:
In other words, if we divide zero by any number, the result will always be zero.
Now we have received the exercise:
Let's solve the exercise:
We'll remember the formula we wrote earlier, and we can see that the result is zero.
So the final exercise will look like this:
Therefore, the appropriate sign is:
=
