Have you ever come across a math puzzle that looks easy but tricks people into giving the wrong answer? This challenge asks a simple question: How old is Sarah?
Sarah gives the following expression:
110 − 10 × 10 + 10 = ?
To solve it correctly, you must follow the standard order of operations. Multiplication comes before addition and subtraction, so start with \(10 \times 10 = 100\).
The expression then becomes:
\(110 – 100 + 10\)
Next, calculate from left to right:
\(110 – 100 = 10\)
\(10 + 10 = 20\)
Correct answer: Sarah is 20 years old!
