Math is often considered difficult, boring, and time-consuming. Many students spend hours solving calculations, memorizing formulas, and practicing equations. But what if there was a simple trick that could make math easier, faster, and more fun?

Surprisingly, nobody talks about this math trick, even though it can save time and improve calculation speed dramatically. Whether you are a school student, competitive exam candidate, trader, or someone who simply wants to sharpen mental math skills, this hidden technique can help you solve problems in seconds.

In this article, you’ll discover one of the smartest math shortcuts that most students never learn in school.

Why Nobody Talks About This Math Trick

Many students are surprised to find that such a powerful mental math shortcut exists, yet it never gets taught in classrooms. The reason is simple: most schools focus on traditional solving methods instead of speed-based techniques. Once students discover this approach, they can solve multiplication problems faster and build real confidence in mathematics.

The Secret Math Trick Explained

The trick is called the “Complement Method” for fast multiplication and subtraction.

This technique works especially well with numbers close to:

• 10
• 100
• 1000

Instead of solving calculations the traditional long way, you use the distance from the nearest base number.

Example 1: Fast Multiplication Trick

Let’s multiply:

98 × 97

Normally, this looks difficult.

But using the hidden math trick:

• 98 is 2 less than 100
• 97 is 3 less than 100

Now follow these steps:

Step 1: Subtract Crosswise

98 − 3 = 95
OR
97 − 2 = 95

Step 2: Multiply the Deficits

2 × 3 = 6

Final Answer

95 | 06

So:

98 × 97 = 9506

Amazing, right?

This trick can solve calculations mentally within seconds.

Why This Math Trick Works

This shortcut is based on mathematical patterns and algebraic relationships.

When numbers are close to a base value like 100, calculations become easier because the differences are smaller and faster to manage mentally.

Instead of multiplying large numbers directly, you simplify the problem into:

• Subtraction — finding the difference between the number and its base
• Small multiplication — multiplying two small deficits instead of large numbers
• Pattern recognition — spotting how numbers relate to 10, 100, or 1000

That’s why mental math champions, stock traders, and competitive exam toppers rely on these shortcut strategies to save time.

Example 2: Another Mind-Blowing Shortcut

Try this:

104 × 106

• 104 is 4 more than 100
• 106 is 6 more than 100

Step 1:

104 + 6 = 110

Step 2:

4 × 6 = 24

Final Answer:

11024

So:

104 × 106 = 11024

This method feels almost magical once you understand it.

Benefits of Learning Math Tricks

Faster Calculations

You can solve problems much quicker during exams or tests.Mental math shortcuts help you solve problems in seconds rather than minutes. During exams, this saved time can mean the difference between attempting all questions or leaving some blank.

Improved Mental Math

Your brain becomes faster at recognizing patterns and numbers.Regular practice with these techniques trains your brain to recognize number patterns instantly, making everyday calculations feel effortless.

Better Confidence

Math stops feeling scary and starts becoming enjoyable.When math becomes predictable and fast, fear disappears. Students who learn shortcuts often start enjoying math instead of avoiding it.

Useful in Real Life

These skills go beyond exams — they help in:

Shopping and budgeting –

Business and trading

Quick mental estimates

Daily problem solving

Why Schools Rarely Teach These Tricks

Most schools focus heavily on traditional methods because they follow standard curriculums. While those methods are important, they often ignore:

• Mental math — solving problems in your head without pen or calculator
• Calculation speed — completing problems faster under exam pressure
• Shortcut strategies—using patterns to simplify complex calculations
• Pattern-based learning—recognizing number relationships instead of memorizing steps

That’s why many students never discover these powerful techniques.

How to Master This Trick Quickly

Practice Daily

Spend 10 minutes every day solving shortcut-based problems.

Start with Numbers Near 100

Examples:

• 96 × 98
• 103 × 107
• 89 × 97

Challenge Yourself Mentally

Try solving calculations without a calculator.Put your calculator aside and attempt at least 5 problems daily using only mental calculation. This builds speed and trains your brain to think in patterns rather than steps.

Use AI Tools for Practice

Modern AI tools like ChatGPT can generate unlimited math problems for practice and learning.Tools like ChatGPT can generate unlimited custom math problems based on your skill level. You can ask for hints, explanations, and progressively harder challenges — making practice sessions more effective than textbooks alone.

Is This Trick Useful for Competitive Exams?

Absolutely — and the impact can be significant. In time-pressured exams, every second counts. Students who master mental math shortcuts can solve numerical questions 2–3x faster, leaving more time for complex problems.

Students preparing for:

– **SAT & GRE**: Quantitative sections require fast arithmetic under strict time limits.

**CSS & banking exams**—numerical reasoning sections reward calculation speed.

**MDCAT & ECAT**—physics and math portions involve rapid number crunching

can save valuable time using fast calculation methods.

In competitive exams, speed matters as much as accuracy.

Final Thoughts

The truth is, most students go through years of schooling without ever discovering how simple multiplication can become with the right approach. Understanding number patterns and base values can completely transform the way your brain processes calculations.

Math doesn’t always have to be complicated. Sometimes a small shift in technique makes difficult problems surprisingly simple.

The more you practice these shortcuts, the faster and more confident you become — not just in exams, but in everyday situations where quick thinking matters.

So next time someone struggles with a large multiplication problem, show them the complement method — and finish the answer before they even pick up a pen.

FAQs

Q: What is the easiest multiplication shortcut for beginners?

A: The Complement Method is ideal for beginners. It works best with numbers close to 100 — you simply find the difference from 100, do a small multiplication, and combine the results. Most people can learn it in under 10 minutes.

Q: Can mental math techniques improve brain power?

A: Yes. Regularly practicing mental calculations strengthens concentration, sharpens memory, and develops logical thinking — skills that are useful far beyond mathematics.

Q: Are these shortcuts helpful in competitive exams?

A: Definitely. In exams like SAT, GRE, MDCAT, and CSS, time is limited. Students who use calculation shortcuts can solve numerical questions significantly faster, giving them more time for complex problems.

Q: Can complete beginners learn these methods?

A: Yes — no prior knowledge is needed. Starting with numbers near 100 and practicing for just 10 minutes daily is enough to see improvement within a week.

Q: Why aren’t these shortcuts taught in schools?

A: Most school curriculums prioritize standardized long methods over speed-based techniques. Mental math shortcuts are rarely part of official syllabi, which is why most students only discover them outside the classroom.
