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