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:
- 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.
- 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.
- 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
-
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.
- 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.
