# Can you solve this simple maths puzzle that has the internet completely baffled?

Updated:

There's nothing like a good old brainteaser to catch the internet's attention.

However, the latest one that has surfaced on Facebook is proving a little tricky for our problem-solving skills.

The maths puzzle - which has already already garnered more than half a million comments and 13,000 shares since it was posted a few weeks ago - involves working out the values of three equestrian-themed symbols - a horse, a horseshoe and a cowboy boot.

Sure it looks simple enough... until you reach the last part of the equation:

Let's start by answering the first three questions:

Question one: 3 horses = 30, so 1 horse = 10.

Question two: 1 horse + 2 horseshoe pairs = 18, so 1 horseshoe pair = 4. Consequently, 1 horseshoe = 2.

Question three: 1 horseshoe pair - 1 cowboy boots pair = 2, so 1 cowboy boots pair = 2. Consequently, 1 cowboy boot = 1.

The final question requires you to add the cowboy boot and the horse and multiply by the horseshoe and that's where things get tricky - with people coming up with answers ranging from 11 to 52.

For the correct answer, you need to look at the Bodmas rule - Brackets, Order, Divide, Multiply, Add and Subtract - the sequence of operations of arithmetic.

And in this case, you need to multiply before you add - so that means the answer is 1 + 10 x 2 = 21.

If 21 is your answer, then congratulations! And if you are still confused, here's a more detailed explanation:
