When children returned to school just weeks ago, you may have given thanks that your days of maths class and homework were well and truly over.

But the latest brainteaser to sweep the web will have you willingly working out sums again.

The puzzle is made up of an equation formed of coloured sticks.

This maths brainteaser will have you staring at the screen trying to work out the answer. The puzzle is made up of an equation formed of coloured sticks

To solve it, you're allowed to move just one stick to make the answer correct.

At first glance it may appear easy - but in fact you might have found just one of the problem's four possible solutions. 

One way to solve it is to turn the six into a zero by moving the green stick in the middle to the right hand side.

This turns the sum into 0 + 4 = 4, which any schoolkid can tell you is correct.  

However, the puzzle can also be solved by transforming the six into an eight bu taking the yellow stick from the plus symbol, creating the equation 8 - 4 = 4.  

But it doesn't stop there. 

The puzzle can also be solved by transforming the six into an eight bu taking the yellow stick from the plus symbol, creating the equation 8 - 4 = 4

By transforming the six into a five, which is easy to accomplish by moving the blue stick and putting it on top of the four at the end of the sum, you're left with 5 + 4 = 9. 

The final way to beat the maths problem is to take the yellow stick from the plus to make it into a minus, then add it below the red stick on the four.

Some may consider this to be cheating. But it turns the four into 1 - 1, leaving you with 6 – 1 – 1 = 4.

And it's not the only recent puzzle to leave people scratching their heads.

A mind-boggling optical illusion is encouraging people to say what they see in the jar, and if it's a couple engaged in a sexual embrace, you might want to look again.

Seemingly disguised in the picture are a number of hidden pictures of animals, but can you see what they are?

Double take: An optical illusions is asking people what they see when they look in the jar

The image is actually made up of nine pictures of dolphins, that work together to make up the outline of the couple.

And what you see first apparently says a lot about your personality.

According to The Independent, your memory will determine whether you first see a couple or dolphins.

Now you see it: While many see a couple engaged in a sexual embrace, the image is actually made up of nine pictures of dolphins

The image, titled 'Message d’Amour des Dauphins', is by the artist Sandro del Prete.

The Independent said the reason why people are able to see the two different pictures is because the brain receives 'equally plausible visual information'.

What you see first will depend on your memory, so while adults are more likely to see the naked couple, children who have no doubt been less exposed to such images will see the dolphins.

The brain teaser is the latest in a series of optical illusions that have left people scratching their heads.

Spot the dots! Mind-boggling optical illusion asked people just how many black dots they can see in the picture. The answer? 12

Most recently, a viral image had people asking just how many black dots they could spot in the picture.

Believe it or not, there were actually 12. 

However, with four dots placed horizontally on the top row, four along the middle and four along the bottom, it seemed almost impossible to see them all at the same time. 

Once the viewer's eyes are fixed on one dot, the others in that row become visible - but the rest in the grid seem to disappear from sight.

How's the view! If you see a lake set against a mountainous backdrop, it's time to have a closer look

Concrete jungle: The 'lake' many people first see in this picture is actually a concrete wall that obscures part of the view

Things are not always as they seem, and a landscape picture of what at first glance appears to be a lake set in front of a mountain is proof of that.

On closer inspection, the photo does not contain any water at all and is in actual fact a concrete wall obscuring part of the scenery.

Another tricky puzzle asks people to look at an iPhone screen with a number of threes on display and determine how many there are.

And while it might sound simple enough, coming to a conclusive answer has the internet divided.

Count to three: People were asked the number of threes they saw on this iPhone screen

If your answer is either 15, 19 or 21, you have arrived at the same conclusion as the majority of social networkers. But which answer is correct? 

There are in fact 19 number threes pictured in the image, but there could be 21 depending on how you interpret the question. 

And if counting is not your thing, it's probably best to look away now.

Feel confused yet? Solving this riddle takes patience, as there are 40 squares hidden in the puzzle

People were also asked to count the number of squares they saw in a picture, and getting it right takes a good deal of patience.

If you manage to count them all, the correct answer is 40. 

The picture is made up of eight tiny squares, 18 single squares, nine 2 x 2 squares, four 3 x 3 squares and one 4 x 4 square.
