O Brain Teaser (in Portuguese, “puzzle”) has several applications. With that, the challenges are not always limited to assembling isolated pieces of an image, as sometimes it can be presented in a different format. Therefore, today we bring you a Brain-Teaser of this type, and to solve it, you must move the toothpicks to fix the equation.

That the mathematical equation 8 – 4 = 61 is wrong, you already noticed, but how to make it correct? Which toothpicks must be changed so that the result is consistent? These are the questions that will guide the line of reasoning to resolve this issue.
Realize that this is a subtraction account, one of the most basic calculations for a beginner in mathematics. With that, don't worry about the difficulty, because much more logical reasoning is needed than resourcefulness in the science of numbers and calculations.
Therefore, to have a quick thinking, it is important to invest your time in tests like this one, which stimulate logical and congruent reasoning. In the end, it is possible to have that feeling of accomplishment and even pride in being able to unravel the secret that many cannot.
This challenge is one of the most difficult of this type of Brain-Teaser, since you have to think “outside the box” to find a way to make this equation true. After much thought, notice that the point of view must be changed after moving the 2 sticks.
If you've already found it, congratulations! We're happy for you, and that means your thinking is great! But if you're having a lot of difficulty, that's okay, because this challenge is really advanced. See the solution in the image below:
If you are still finding something strange, you are correct! Note that, for the equation to make sense, it will need to be turned upside down, after all 61 – 11 will never equal 8. With that, the toothpicks must be observed from another angle. Check out the final photo for the resolution, which is actually 19 – 11 = 8.
