Maths tricks are the road to quickly and efficiently solving complex math problems. Math isn't just something you can learn from books. There are other ways to learn math that can make it easier. Simple math tricks help us figure things out quickly and help us get better at math.

Some kids have trouble with math. The math tricks are helpful for students and help you keep track of time so you can answer math questions correctly in competitive exams and in real life.

The best way to make math a fun subject is to teach math tricks. So, learning simple math tricks will help students feel better about themselves and improve their problem-solving ability. With these tips, they can do very well on competitive exams and in the future. Here are 5 such tips:

  1. Addition
  • Take 53 + 44.
  • Based on tens and units places, split the second number: 44 = 40 + 4
  • Finish the ten's addition. 53 + 40 = 93
  • Finally, add the remaining unit place digit. 93 + 4 = 97.
  1. Quick Multiplication
  • Let's try the numbers 28 and 14
  • First, split the number 28, which gives 4 x 7
  • Then multiply 7 by 14, and we get 98
  • Finally, multiply the number 98 x 4 = 392
  • So, 28 x 14 gives 392.
  1. Multiplication of Two-Digit Numbers when one number is even:
  • Consider an example, 12 x 37
  • Here 12 is an even number. Divide it in half so that 12/2 = 6
  • Then double the second number. 37 x 2 =74
  • Finally, multiply both answers. It becomes 74 x 6 = 444
  1. Percentage

    Let's find 5% of 375:

  • First, Move the decimal point over by one place for the given number.
  • 375.0 becomes 37.5
  • Then divide the number 37.5 by 2, and we get 18.75.
  • The answer to 5% of 375 is 18.75.
  1. Squares of numbers ending with the digit 5
  • Let's take the number 85 and try to find its square.

  • We know that the square of 5 is 25. Note that down.

  • Next, take the first digit of the number 85. That is 8. Then take the number that comes after 8, which is 9.

  • Now, multiply 8 and 9, and we get the number 72.

  • Finally, write the number 72 before the number 25 (which you wrote down earlier). So, what you get is 7225, which is the answer.

  • A simple formula would be:

    The square of n5, where n is the first digit = n(n+1)100+25.

    Let's use this formula and try again with the same number, 85.

    So, square of 85 = 8(8 + 1)100 + 25 = (8 x 9)100 + 25 = 7200 +25 = 7225. Did these tricks help you? There are many tricks like this that make maths fast and fun.

Exploring Glow & Lovely Careers' Interest Test Helped Pragya Rai Make an Informed Choice for a Future in Civil Services

When you are a young woman and looking to make your mark in society, coming to a decision about how to do it can be especially confusing. You might get a lot of suggestions from a lot of people and it can mean even more chaos. Sometimes your friends can suggest things that you might like in the first instance, but once you explore that option, you realize, it isn't as suitable for you as it might have seemed. If you can relate to that sense of confusion and stress about your future as a contributing woman in society, you should take inspiration from the story of B.Com student Pragya Rai.

Pragya Rai hails from the city of Varanasi. As a college student, she decided to play it safe and seek a course that would enable her to have multiple options when it came to career opportunities. "I thought the whole reason to take B.Com was to see what interested me in college. Taking a generic course would allow me to understand what options I had for my future career and figure out what it is exactly that I might be good at."

In her conversation with friends, she realized there was a lot of different information about career opportunities. It was confusing and sometimes she realized that there was a lot of unintentional misinformation too. She had felt that it was a repeat of the same experience she had had in high school as well. Pragya says, "When I was in high school I was very confused if the things I wanted to do would be right for me. It is very difficult to get career counseling or, say, good guidance, for free in my city."

Luckily for Pragya, she decided to take the search for help online. She looked for free online career counseling options and even free career tests online. Eventually, she stumbled on to the Glow & Lovely Careers (formerly known as Fair & Lovely Career Foundation) career test online.

"The test was free, quick and easy to take.", says Pragya.

Even while she was struggling with coming to a firm decision about her future career, Pragya knew that she wanted to make a difference. Her determination might not have had a concrete direction, but she had a gut instinct about her ambitions. Her free online career guidance test results showed her the right course of action. "The results reassured me that civil services would be the right career for me. It gave me the much-needed confidence to pursue my dream." With the clarity that was previously missing, Pragya is now busy in college, completing her B.Com course on one hand and preparing wholeheartedly for a career in civil services on the other.

Pragya's story shows us the power of curiosity. As a young woman in the world, it is important to explore. It helps you better understand what you actually want to do. It also helps you explore opportunities that you might be unaware of. In Pragya's instance, she took a chance and searched for career guidance online and it led her to discover Glow and Lovely Careers' (formerly known as Fair and Lovely Career Foundation) interest-based test andpsychometric test for career planning. So, if you are someone who is also in need of career guidance, take this opportunity and head to the Glow and Lovely Careers website for more information to decide on your long-term career choices.
