Solve the Number Sequence: 0, +15, -16, ?0

Question

Fill in the missing symbol (?):

$0:+15:-16\text{?}0$

00:06 Let's start by completing the correct sign.

00:11 We'll solve from left to right, one step at a time.

00:16 Remember, we'll write division as a fraction.

00:19 Zero divided by any number is always zero.

00:23 Let's substitute in our example and keep solving.

00:37 Again, zero divided by any number gives us zero.

00:43 And that's how we find the solution!

Let's solve the exercise from left to right:

$\frac{0}{15}=$

Remember the formula:

$\frac{0}{x}=0$

If we divide zero by any number, the result will always be zero.

Now we are left with the following exercise:

$0:-16?0$

Let's solve the exercise:

$\frac{0}{-16}=$

If we remember the formula above, we should see that the result is zero.

The final exercise will look like this:

$0\text{?}0$

Therefore, the missing sign is:

$0=0$
