Have you ever wished for a faster way to solve math problems in exams? Speed and accuracy play a huge role in competitive exams, making quick calculation skills essential. Mastering the right techniques can save valuable time and boost confidence during tests.
This article explores six effective maths simplification tricks that help aspirants solve problems quickly. Learning simple yet powerful shortcuts can boost confidence and improve accuracy. Let’s dive into these powerful techniques and enhance your calculation speed.
Mastering the BODMAS Rule for Faster Calculations
Every numerical problem follows a specific order of operations for accurate results. Using the BODMAS rule ensures that complex expressions are solved step by step without confusion. This method involves handling brackets first, followed by orders, division, multiplication, addition, and subtraction.
Ignoring the BODMAS rule can lead to incorrect answers and wasted time during exams. Many examiners deliberately set traps for students who fail to follow the correct order of operations. By consistently applying BODMAS, aspirants can develop a structured approach to solving numerical problems.
Breaking Down Large Numbers for Easy Computation
Simplifying large numbers can make calculations more manageable in exams. Breaking numbers into smaller, more convenient parts helps in quick multiplication and division. For example, solving 98 × 102 becomes easier by expressing it as (100 – 2) × (100 + 2).
This technique is especially useful in exams where time constraints make long calculations challenging. Breaking numbers into simpler components helps in mental calculations without requiring a calculator. Applying this method to real-life scenarios like calculating discounts or percentages enhances mathematical intuition.
Approximation Techniques to Save Time
Using estimation can help in arriving at answers quickly when exact calculations are unnecessary. Rounding off numbers to the nearest tens, hundreds, or thousands can simplify complex problems. For instance, estimating 498 × 23 as 500 × 23 gives an approximate answer instantly. This method is especially useful in competitive exams where speed matters.
Approximation also plays a crucial role in quickly eliminating incorrect answer choices in multiple-choice questions. By estimating the nearest possible values, aspirants can often select the right answer without full calculations. This method is particularly useful in banking and government exams, where solving hundreds of numerical questions is necessary.
Doubling and Halving Method for Quick Multiplication
Multiplication becomes faster when numbers are adjusted into simpler forms. Doubling one number while halving the other can make calculations easier. For example, solving 25 × 48 is simpler when rewritten as (50 × 24). This technique reduces effort and enhances accuracy in exams.
This method is particularly beneficial for solving questions without paper or a calculator. It works exceptionally well for numbers ending in 5 or even numbers that can be divided by 2. With enough practice, aspirants can perform mental calculations quickly without needing long multiplication methods.
Squaring Numbers Ending in 5 Instantly
Finding squares of numbers ending in 5 follows a simple pattern. The last two digits of the square always end in 25, and the first part comes from multiplying the remaining number with its next integer. For example, the square of 35 is calculated as (3 × 4) followed by 25, resulting in 1225. This method not only helps in squaring numbers quickly but also strengthens mental calculation skills. Being able to find squares instantly improves performance in sections involving algebra, percentages, and profit-loss calculations.
Simplifying Fractions to Speed Up Division
Dealing with fractions efficiently can make division problems easier. Converting fractions into simpler forms before solving reduces complexity. For example, 48/96 simplifies to 1/2 instantly without manual division. Identifying common factors helps in reducing steps and avoiding unnecessary mistakes. Exam preparation experts recommend practicing fraction simplifications regularly.
Mastering these simplification shortcuts enhances problem-solving speed and improves exam performance. Using maths simplification tricks ensures better accuracy and faster results in exams. Practicing these techniques regularly helps aspirants handle tricky numerical problems confidently. Strengthening these skills through practice leads to success in competitive tests.
