"summary",
"The problem seems easy to solve, but it can be challenging even for people with advanced knowledge. The key is to follow the mathematical hierarchy, also known as PEMDAS, which establishes the order in which to resolve the different parts of a calculation. The hierarchy is: parentheses, exponents, multiplication and division from left to right, and finally addition and subtraction from left to right."
