The proof that I present to you now probably does not attract much attention. And it has equations that a primary school child develops daily, but what do you think if I tell you that there are few Internet users who passed the math challenge? The challenge gets interesting, right? Here you must find the value of each object that appears on the graph and, after that, obtain the result of the last exercise. Come on!
In the image you can see addition and subtraction equations made with images of cheese and mice that, evidently, replace numbers. Your mission is to determine what those numbers are. Are you ready for this new mathematical challenge?

Solution to the mathematical challenge
Let’s analyze the first equation:
Cheese + cheese + cheese = 108. It means that each cheese is equal to 36.
Second equation: Something curious happens here. The cheeses do not have the same number of holes as the first equation, they only have 5. So, we deduce that each egg is equivalent to 6, therefore:
Cheese + cheese + mouse = 30 + 30 + mouse = 72. So, mouse is 12.
Third equation: In this one the cheese only has 4 holes, so:
24 – 12 = 12.
Fourth equation:
Cheese (with 4 holes) + mouse + mouse = ? We replace: 24 + 12 + 12 = 48.
In what order are mathematical equations solved?
In mathematics, the order of solving operations follows the PEMDAS rule: Parentheses, Exponents, Multiplication and Division (from left to right), and finally Addition and Subtraction (from left to right). This rule establishes the priority of operations and ensures consistent resolution of complex mathematical expressions. Remembering PEMDAS is essential to avoid confusion and obtain accurate answers.
