Class 7 Maths Trick to Solve Problem Faster

Mathematics is a discipline that is either loved or found to be challenging by many students. However, one thing is universal: it is more pleasant when problems are solved more quickly. In class 7, Class 7 maths books become more difficult when new concepts such as integers, algebra and geometry are introduced. Solving questions might be time consuming, but with some smart tricks, you can easily solve them with few errors.

Why is it useful to learn Maths tricks?

Mathematics may be enjoyable if you know the appropriate tricks. With these strategies, you can effortlessly solve questions from your CBSE 7 Class Maths book or any other book. You may be able to solve large calculations present in the question bank of Class 7 in less time.

It is essential that you understand their significance before knowing the tricks-

• These tricks save time and boost confidence.

• Improves your math skills so you can do simple calculation on your own.

• Helps in competitive exams like scholarship test and olympiads.

• Increases the speed of calculation.

• These tricks are also helpful in solving your CBSE books class 7 problems.

Top Maths Trick which can Solve problem Faster-       

1. Multiplication Shortcuts -

Multiply By 9- In this trick, if any number which is multiply by 9, multiply it by 10 then subtract the original value

EXAMPLE:  27×9

multiply by 10- 27×10= 270

                       270 -27= 243

so the result is, 243

Multiply By 11- Firstly, separate the original value and add them and place the added number between the original value,

EXAMPLE:  42×11

                 4_2, 

                 4+2=6, (place this 6 in between 42)

Result is, 462 

2. Rules Of Divisibility for fast Verification-

These rules are key tools in Maths that can help the students to determine if the number can be divided by another number or not, without doing the division.

Rule for 2- Ends in an even number like 0,2,4,6,8

Rule for 3- A Number Can be divisible by 3 if the sum of these numbers can divisible by 3 -

EXAMPLE: 

  145 - 1+4+5= 10 (not divisible by 3)

  143 - 1+4+3= 6   (divisible by 3 )

Rule for 5- If the value ends in 0 or 5 divisible by 5

Rule for 6- If the value divisible by 2 or 3 then it can be divisible by 6 also,

Rule of 9- Sum of digits divisible by 9, like Rule of 3 

3. Percentage Calculations in a Easy Way-

To find Percentage firstly, break it down into simple components,

EXAMPLE: 15% of 300

                   10% of 300 = 30

                    5% of 300 = 15

                    10% + 5%, 30+15= 45 

Result is, 45

4. Simplification (BODMAS)

In Mathematics, BODMAS is a fundamental rule that helps students to solve complicated arithmetic expressions by follow that order,

BODMAS Stands For-

B- Brackets

O- Orders ( Powers and roots )

D- Division

M- Multiplication 

A- Addition 

S- Subtraction 

           EXAMPLE:         8+[12÷(3×2)]- 4,

           Solve (3×2),       8+[12÷6]- 4,

                                      8+2- 4,

                                      10- 4= 6

          Result is, 6

5. Squaring Number Ending with 5-

For the numbers like 25,15,35,45, etc

EXAMPLE: 25^2

Multiply the first digit with the next number of the digit, 2×3= 6

then put 25 after the 6 or result, 625

Result is, 625                                    

Mathematics is more than just numbers; it's also about using reasoning and problem-solving techniques. For learning math tricks, Oswaal Books also provides many books including Math Olympiad books for Class 7 which are a helpful resource for students. They use logical ideas, shortcuts, and step-by-step ways to simplify complicated topics.
