IQ tests come in various forms, each designed to measure different aspects of our intelligence. One effective method is through math equations, which test our reasoning and logical thinking skills. Today, I present you with a simple yet tricky math problem. Can you solve it in under 30 seconds?

The Puzzle

To tackle this puzzle, you’ll need to focus and quickly determine the correct answer. The equation uses basic arithmetic operations: addition (+) and multiplication (×). Here’s the equation:

5+5×5+5=?5 + 5 \times 5 + 5 = ?5+5×5+5=?

You have four possible answers to choose from. The clock is ticking, so let’s see how sharp your math skills are!

Solving the Equation

When faced with a math problem like this, it’s crucial to remember the order of operations, often recalled by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Following this rule will lead you to the correct answer.

Personal Anecdote

I recall encountering problems like this back in school. We’d often have quick math drills to test our speed and accuracy. I can still picture my old teacher, Mr. Thompson, pacing around the room with a stopwatch in hand, eagerly waiting to see who could solve the problem the fastest. It felt like a high-stakes game, and the thrill of getting the answer right was always rewarding.

The Solution

Let’s break it down:

5+5×5+55 + 5 \times 5 + 55+5×5+5

According to PEMDAS, we first solve the multiplication:

5+(5×5)+5=5+25+55 + (5 \times 5) + 5 = 5 + 25 + 55+(5×5)+5=5+25+5

Next, we perform the addition:

5+25+5=355 + 25 + 5 = 355+25+5=35

So, the correct answer is 35.


Did you solve it in under 30 seconds? If so, congratulations! You’ve demonstrated quick and accurate reasoning skills. If not, don’t worry. Math puzzles like this are a great way to sharpen your mind and improve your problem-solving abilities.

Share this challenge with your friends and see who can solve it the fastest. Keep practicing, and remember, the more you exercise your brain, the sharper it gets. Happy puzzling!
