Math is more than just numbers and equations—it’s about nurturing a lifelong skill that shapes our everyday decision-making, analytical thinking, and problem-solving abilities.
Maths often gets a reputation for being difficult or boring, but we believe it’s anything but that! Especially when you have a few clever tricks up your sleeve. So, in honour of this year’s Maths Day celebration, we’re diving into 7 fast tricks for solving problems that will not only help students but also make maths genuinely fun and approachable for everyone.
Whether you’re preparing for an exam, helping a child with homework, or just looking to sharpen your brain, these math problem solving tricks are sure to come in handy.
Trick 1: Multiplying by 9 Using Your Fingers
Here’s a Fast Maths Trick that’s as fun as it is useful—and you only need your fingers!
Let’s say you want to multiply 9 by any number from 1 to 10. Hold out both your hands in front of you. Now, if you’re multiplying 9 × 3, fold down your third finger. You’ll be left with 2 fingers on the left and 7 on the right. That’s 27!
This visual method is great for young learners and makes maths problem solving tips engaging and interactive. Plus, it’s a fantastic party trick during your next Maths Day celebration!
Trick 2: The Magic of Square Numbers
Did you know that squaring numbers ending in 5 is actually super simple?
Here’s how: To square a number like 25, take the first digit (2), multiply it by the next whole number (3), which gives you 6. Then, add 25 at the end. So, 25² = 625.
Let’s try 65²:
- Take 6 × 7 = 42
- Add 25 → 4225
This method is perfect when you’re aiming for easy math solutions and want to impress your classmates or colleagues with lightning-fast calculations.
Trick 3: The Rule of Divisibility
Let’s talk about one of the most underrated math techniques for students—divisibility rules. These are quick checks to see if a number can be divided by another, without actually doing the division.
Here are a few to remember:
- Divisible by 2: Ends in 0, 2, 4, 6, or 8
- Divisible by 3: Sum of digits is divisible by 3
- Divisible by 5: Ends in 0 or 5
- Divisible by 9: Sum of digits is divisible by 9
Knowing these rules makes it easier to solve math problems faster—especially during competitive exams or quizzes.
Trick 4: Simplifying Fractions Quickly
Ever looked at a fraction and thought, “This looks messy”? Here’s how to tidy things up in seconds!
Let’s take 36/48. Both numbers are divisible by 12, so: 36 ÷ 12 = 3
48 ÷ 12 = 4
Your answer is 3/4.
To do this quickly, look for the Greatest Common Divisor (GCD). With a little practice, spotting it becomes second nature. This trick is a must-know for students who often deal with fractions in homework or tests, and a vital part of any solid problem solving strategies in math.
Trick 5: Fast Multiplication with Large Numbers
Large number multiplication can be intimidating, but here’s a simple way to make it manageable:
Let’s try multiplying 103 × 107.
- First, find the average: 105
- Then, subtract the difference (3 and 7) from 100 → the product will be:
- 10000 + (3 × 7) = 10000 + 21 = 11021
You’re using the formula:
(a + b)(a – b) = a² – b²
With a twist!
This method saves time and works wonders for mental math techniques.
Trick 6: The Power of Estimation
We can’t stress enough how helpful estimation is in everyday life. Whether you’re budgeting at the grocery store or trying to calculate time and distance, this is one of those quick math tips for students that carries into adulthood.
Here’s how it works: Instead of multiplying 49 × 19, round it off to 50 × 20 = 1000. Now, you know your actual answer will be slightly less. This helps you arrive at a close answer quickly—great for MCQs or saving time during exams.
It’s one of our go-to speed math solutions, especially when precision isn’t crucial.
Trick 7: Speedy Subtraction Using Complementary Numbers
If subtraction gives you a headache, this trick will change your life!
Let’s say you’re doing 1000 – 647. Instead of writing it out, subtract each digit from 9, except the last one, which you subtract from 10.
9 – 6 = 3
9 – 4 = 5
10 – 7 = 3
Answer: 353
This works beautifully for subtracting from round numbers like 1000, 10000, etc. We use it often in maths day activities when playing games with numbers!
