# Get the answer to our tricky Halloween math puzzle!

So, how did you do?

We posed this tricky Halloween puzzle on social media:

And lots of you had a try at working out the answer - but did you get it right?

The answer is...

(drumroll, please...)

...

**15**

Ta-da!

But how?

First, we can figure out that Komodo = 10 by dividing the answer, 30, into three equal amounts, which gives us 10.

**30 ÷ 3 = 10**

With the second equation, knowing that a Komodo is 10, we can take 10 from the answer to tell us what the pumpkins are together.

**20 - 10 = 10 **

...so two pumpkins =10, making one pumpkin = 5.

We move on to the third equation and can find out the value of the groups of bats in the same way. Take the pumpkin (5) away from the answer (9) to get 4.

**9 - 5 = 4**

Two groups of bats = 4, so one group of bats is 2.

For the last equation, we know all the values - but we need to look carefully because there is only one bat in this equation. If a group of two bats = 2, then one bat = 1.

Which means that the final calculation we need to do is:

**5 + 1 x 10 =**

And this is the part where we use the order of operations law, or PEDMAS, which means that we multiply numbers before adding them. So we do the calculation 1 x 10 first, to get 10 then add this to 5 to get 15.

If you got 60, you did the adding first, which is an easy mistake to make!

Here's a little graphic to tell you a bit more about the order of calculations, or what PEDMAS stands for:
