I still remember the moment like it was yesterday.
I was in my second year of engineering college, staring blankly at my notebook. The page was covered in messy formulas—trigonometric identities, calculus tricks, and a web of algebraic expressions that made my head spin. Despite spending hours on these concepts, nothing seemed to stick.
That’s when a senior whispered a life-changing word to me: mnemonics .

What Are Mathematics Mnemonics?
At first, it sounded like a fancy psychological term. But I quickly discovered that mathematics mnemonics are simple memory tricks—short phrases, rhymes, or patterns—that help you remember complex math formulas or steps with ease.
It’s like giving your brain a shortcut through a jungle of formulas.
And the best part? These aren’t just for kids. As an engineering student, entrepreneur, and now a co-founder of innovationforu.com, I still rely on mnemonics every now and then. They help me in brainstorming product ideas, building math-based calculators, and even during tech consultations with startup teams.
Let me walk you through some of the best mathematics mnemonics that saved my academic journey and now empower my professional life.
Mnemonics for Order of Operations (PEMDAS)
Problem: Ever messed up a math equation by solving in the wrong order?
Solution: Use this classic mnemonic:
“Please Excuse My Dear Aunt Sally.”
It stands for:
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
This is one of the most famous mnemonics and a true lifesaver when dealing with algebraic expressions or coding embedded systems that require mathematical logic.
✅ I’ve even used it while designing control logic for a robotics prototype. It works like magic.
Maths Mnemonics Examples for Algebra
Problem: Algebra was a minefield of signs and variables for me.
Solution: Here’s one that stuck with me:
“My Dear Aunt Sally” also works great for simplifying algebraic steps. But when it comes to formulas, I often used:
“FOIL” for binomial multiplication:
- First
- Outer
- Inner
- Last
Example:
(x+3)(x+2)=x2+2x+3x+6(x + 3)(x + 2) = x² + 2x + 3x + 6(x+3)(x+2)=x2+2x+3x+6
Using FOIL made this automatic.
👉 Trust me, whether you’re solving equations or working on a circuit algorithm, such math mnemonics for algebra make things a lot smoother.
Mathematics Mnemonics Formula: Trigonometry Made Easy
I struggled with trigonometric identities until I met the gem:
“Some People Have Curly Brown Hair Through Proper Brushing.”
It decodes as:
- S = P/H (Sine = Perpendicular / Hypotenuse)
- C = B/H (Cosine = Base / Hypotenuse)
- T = P/B (Tangent = Perpendicular / Base)
These mnemonics for maths formula helped me not only clear my semester exams but also assist others during doubt-solving sessions.
🎯 Pro tip: When I tested this trick during a quiz I hosted for embedded engineers, 90% of them recalled the values correctly.
Math Mnemonics in Engineering and Real Life
You might think: “Mnemonics sound fun, but do they really help in real life?”
Absolutely.
Here’s how:
- During coding interviews, I’ve seen candidates recall logic gates and binary operations using quick mnemonics.
- While pitching a product idea to an investor, a startup founder I mentored used a formula-based mnemonic to explain his AI model’s learning curve.
- In microcontroller programming, calculating resistor values or delay times becomes easier with little phrase hacks.
Even if you’re building a research paper, presenting data with correct formulas becomes less stressful when you’ve embedded these tricks into your mind.
Mnemonic Devices for Math in Competitive Exams
If you’re preparing for GATE, GRE, or campus placements, mnemonic devices for math give you an unbeatable edge.
Here are a few that I used:
- “All Science Teachers Are Crazy” – For signs of trigonometric functions in each quadrant:
- All Positive (1st Quadrant)
- Sine Positive (2nd)
- Tangent Positive (3rd)
- Cosine Positive (4th)
- “I Saw Her Across The Hall” – For the integral of sin(x), cos(x), etc.
🧠 These are not just memory aids—they’re confidence boosters. They help reduce test anxiety and boost performance.
My Favorite Mnemonic Math Stories
One of my most cherished memories is from my final-year project. I had to calculate sensor readings, signal transformations, and feedback loops. Instead of fumbling with 12 different formulas, I leaned on my mnemonic math notes.
Not only did I complete my project before the deadline, but I also got the highest project evaluation score in my batch.
🙌 Mathematics Mnemonics don’t just save time—they amplify performance.
How to Create Your Own Mathematics Mnemonics
You don’t have to rely on old tricks—make your own!
Here’s how:
- Use Rhymes: Rhyming phrases are easier to remember.
- Relate to Your Life: Use personal references (e.g., names of friends or professors).
- Be Visual: Imagine a scene or character for each element.
- Keep it Funny or Odd: Weird things stick better!
✍️ Example:
To remember the quadratic formula:
“X is equal to minus B, plus or minus the square root of B squared minus 4AC, all over 2A.”
Sing it like a jingle—boom, it’s stuck in your head forever.
Why Mathematics Mnemonics Work (According to Science)
Cognitive science explains that mnemonics engage multiple parts of your brain—language, memory, and emotion. They make learning interactive and sticky.
This is why both students and professionals across domains—from IT engineers to entrepreneurs—use them daily.

Final Thoughts: Don’t Just Study Math—Play with It
As someone who now builds tools and platforms for young techies, I believe learning should never feel like a burden.
With mathematics mnemonics, you turn frustration into fun and formulas into friends.
So the next time you feel stuck, don’t push harder. Think smarter. Use a mnemonic.
