It’s 36.
If you just wanted the answer to 6 to the second power, there it is. You don't need a math degree to punch that into a calculator. But honestly, if you're looking this up, you're probably either helping a kid with homework, refreshingly honest about forgetting middle school math, or you're curious about why exponents rule the world of computing and physics.
Math is weird. We spend years learning it in school, and then we spend the rest of our lives trying to remember if the little number means "multiply by two" or "multiply by itself." It’s the latter. When you see $6^2$, you’re basically looking at a shorthand for a square. Imagine a physical square made of tiles. If it's six tiles wide and six tiles high, you've got 36 tiles. That’s the "square" in "squaring a number." Simple, right? But the implications of this basic arithmetic ripple through everything from the way your phone processes images to how architects make sure buildings don't fall over during an earthquake.
The mechanics of 6 to the second power
Let's break down the anatomy of the expression. You have the base, which is 6. Then you have the exponent, or the power, which is 2. In mathematical notation, we write this as $6^2$.
Calculators handle this instantly. If you’re using a scientific calculator like a TI-84 or even just the app on your iPhone, you might see a button that looks like $x^2$ or a little caret symbol (^). Typing 6^2 tells the machine to execute a specific algorithm: take the base and use it as a factor as many times as the exponent indicates. Since the exponent is two, we do $6 \times 6$.
It's a common trap to accidentally do $6 \times 2$. Everyone does it. Even engineers occasionally make that mental slip when they're tired. But $6 \times 2$ is 12, a linear growth. $6^2$ is 36, which represents quadratic growth. The difference between 12 and 36 is the difference between a minor error and a catastrophic structural failure in a bridge design.
Why do we call it "squared"?
The terminology comes straight from geometry. Ancient mathematicians, like those in the school of Pythagoras or Euclid, didn't think of numbers as abstract symbols on a screen. They thought of them as lengths and areas. When you multiply a number by itself, you are literally finding the area of a square with that side length.
If you have a garden that is 6 feet by 6 feet, you have 36 square feet of space. This is why we don't say "6 to the two-power" very often. We say "6 squared." It’s a linguistic fossil from a time when math was something you could touch and measure with a piece of string.
Real-world applications of squaring numbers
You might think you’ll never use 6 to the second power outside of a classroom. You'd be wrong.
Take photography and lighting, for example. There is something called the Inverse Square Law. It’s a fundamental principle of physics. Basically, if you double the distance from a light source, the intensity of the light doesn't just drop by half. It drops by the square of the distance. If you move 6 meters away from a light, the brightness is $1/6^2$ (or 1/36th) of what it was at one meter. This is why stage lighting and flash photography require such precise calculations. A small step back means a massive loss in light.
Then there’s the world of computer science. If you’ve ever heard of "O(n squared)" complexity, you’re looking at exponents in action. In programming, some algorithms get exponentially slower as you add more data. If an algorithm has a complexity of $n^2$, and you give it 6 pieces of data, it takes 36 "steps" to finish. If you give it 10 pieces, it takes 100 steps. Understanding these jumps is how software developers keep your apps from freezing up when you load a large contact list.
Computing and Binary
While we use base 10 in our daily lives, computers use base 2. However, we often group things in powers. While 6 isn't a power of 2, the math behind exponents is what allows for memory addressing and data storage. We measure things in kilobytes, megabytes, and gigabytes—all of which are built on the back of exponential growth. When we talk about $6^2$, we are practicing the same logic used to calculate the bandwidth needed for a 4K video stream.
Common misconceptions and "Math Trauma"
A lot of people have what educators call "math anxiety." It usually starts around the time exponents are introduced. Why? Because math stops being about counting fingers and starts being about abstract rules.
One big mistake people make with 6 to the second power is confusing it with scientific notation or different bases. Others struggle with negative numbers. For example, $-6^2$ and $(-6)^2$ are not the same thing.
- In $-6^2$, you square the 6 first to get 36, then make it negative: -36.
- In $(-6)^2$, you are multiplying -6 by -6, which gives you a positive 36.
This little distinction causes more failed algebra tests than almost anything else. It's about the order of operations—PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Exponents are right at the top of the hierarchy, just under parentheses. They are powerful. They change the value of an expression faster than almost any other operation.

The psychology of numbers
There is also something satisfying about the number 36. It’s a "highly composite number" (though technically that term refers to numbers with more divisors than any smaller number, 36 is a great example of flexibility). You can divide 36 by 1, 2, 3, 4, 6, 9, 12, 18, and 36. This makes it a favorite for package designers and architects. It fits into grids perfectly. It’s why a "yard" is 36 inches—it’s easily divisible into halves, thirds, and quarters.
Beyond the second power: What happens next?
If 6 to the second power is a square, 6 to the third power ($6^3$) is a cube. That takes us from area into volume. $6 \times 6 \times 6 = 216$.
Notice how fast that grew? We went from 6 to 36, then suddenly to 216. This is the "exponential curve" people talk about in finance or virus transmission. While $6^2$ feels manageable, $6^{10}$ is 60,466,176. Exponents are a lesson in how quickly things can get out of hand. In the financial world, compound interest is essentially an exponent at work. If your investments grow at a certain rate, you aren't just adding money; you're "squaring" (or more) your growth over time.
Does this matter for the average person?
Honestly, yeah. Understanding how powers work helps you sniff out BS in the news. When someone says a risk has "doubled" or "squared," you need to know what that actually means for the final result. If the base risk was small, $6^2$ is just 36. But if the base was large, that exponent becomes a monster.
How to calculate exponents mentally
If you find yourself without a phone and need to square a number like 6, or something slightly harder like 16, there are tricks. For a simple one like 6 to the second power, rote memorization is usually the way to go. Most people learn their "squares" up to 12 in elementary school.
But for larger numbers, you can use the distributive property. To square 16, you could do $(10 + 6)^2$. That expands to $10^2 + 2(10 \times 6) + 6^2$.
That’s $100 + 120 + 36 = 256$.
See? The 36 we got from $6^2$ is a component of the larger calculation. Math is just a series of small blocks stacked on top of each other. If you know the small blocks—like the fact that $6^2 = 36$—you can build anything.
Practical ways to use this today
Don't just let this be a trivia point. Use it to understand the world.
- Check your flooring: If you're buying tile for a 6x6 bathroom, you need 36 square feet. Always buy 10% more for cuts, so grab 40.
- Understand your tech: When you see "64-bit" or "32-bit" computing, remember those are exponents ($2^{64}$). The jumps between those numbers are massive, not incremental.
- Cooking scales: If you increase the diameter of a circular pizza from 6 inches to 12 inches, you aren't getting twice as much pizza. You're getting four times as much because the area depends on the square of the radius ($r^2$).
6 to the second power isn't just a line in a textbook. It's the math of the physical world. It’s the difference between a line and a shape. It's the foundation of how we measure space, light, and data. Next time you see that little "2" floating above a number, remember it’s not just a multiplier—it’s an entirely new dimension.
Next Steps for Mastery:
- Memorize the first 15 squares: Knowing $1^2$ through $15^2$ by heart makes mental estimation significantly faster in daily life.
- Apply the Inverse Square Law: Next time you're using a flashlight or a lamp, move it twice as far from the wall and observe how the light spreads and dims by a factor of four.
- Practice Order of Operations: Solve a few expressions like $3 + 6^2 \div 2$ to ensure you're handling exponents before addition. (The answer is 21, by the way).
