Are you tired of fumbling with your calculator every time you face a math problem? Do you envy those who seem to effortlessly perform complex calculations in their heads? The secret lies in the realm of mental maths!
In this article, we will dive into the world of mental maths tricks and techniques that can supercharge your number-crunching abilities. Whether you’re a student, professional, or simply intrigued by the power of the human mind, read on to discover the magic of mental maths.
What is Mental Maths?
Mental maths, simply put, is the ability to perform mathematical calculations in your mind, without the aid of external tools like calculators or pen and paper. It involves using multiple strategies and techniques to arrive, with practice quickly, at accurate solutions. This skill isn’t just a party trick; it has numerous real-life applications; from splitting bills at a restaurant to making financial decisions.
Why Should You Learn Mental Maths?
Enhancing your mental maths skills offers a range of benefits:
- Speed and Efficiency: Imagine being able to calculate tips, discounts, or change instantly. Mental maths allows you to arrive at answers much faster than reaching for a calculator.
- Brain Workout: It is like a workout for your brain. Regular practice sharpens your cognitive abilities, improving overall problem-solving skills. Apart from that, just like other exercises provide health benefits, mental maths provides great health benefits for your brain.
- Confidence Boost: As you master mental maths, your confidence in tackling numbers grows. This newfound confidence can spill over into other areas of your life.
- Accessible Everywhere: You don’t always have a calculator on hand, but your brain is always with you. Mental maths enables you to perform calculations anytime, anywhere.
Techniques and Tricks for Mental Maths
- Breaking Down Numbers
Breaking down numbers into simpler components, or units, makes calculations easier. For instance, when multiplying 27 by 4, think of it as (20 * 4) + (7 * 4) for a faster solution. If you struggled with getting that quickly, it is okay, practice makes perfect. The answer is a hundred and eight.
- Round and Adjust
Rounding numbers to the nearest tens or hundreds can simplify calculations. After arriving at the answer, adjust for the rounding to get an approximate solution. For instance, instead of trying to calculate 9 * 8, multiply 10 and 8. You’ll get 80 but you know it has to be less than that, 8 less actually, leaving you with 72. Test yourself like this with a calculator and you’d be surprised how quickly you can accurately guess large numbers (or get really close).
- Doubling and Halving
Multiplying by 2 is the same as doubling and dividing by 2 is halving. Utilize this technique for multiplication and division to simplify complex operations. Combine this with rounding and adjusting to simplify real-life situations dramatically.
- Using Patterns
Numbers often follow patterns. For multiplication, the distributive property (a * b) = a * (c + d) can be useful. This turns complex multiplications into simpler ones.
- Squaring Numbers Ending in 5
To square numbers ending in 5, multiply the number formed by the digits before 5 with the next number.
For example, 252;
2 * 3 = 6.
Thus 252 = 625.
