CBSE Board Class 10 Maths - The Magic Stick of the Topper
How To Increase the Number in Maths, CBSE Board Class 10 Maths : In the CBSE (Central Board of Secondary Education) Board Class 10 Mathematics examination, a student can score not less than 40 marks out of 100 in total, and if he or she scores 50 marks, it would be very much appreciated by the board, as well as by his or her parents. When one has less marks than this, there are chances that he or she may not qualify to move on to higher classes like 11th and 12th because of lower scores in 10th exams.
How to solve complex questions in 6 simple steps
If you are having a hard time solving an exceptionally complex problem, start by breaking it down into its basic components. For example, if you’re trying to solve 9x2 + 12x – 15 = 0, break it down into each step: (9x)2 + 12x – 15 = 0 and then 9x(2+1) + 12x – 15 = 0 and finally 9x3 +12x –15=0. At first glance, these questions may seem far more intimidating than a simple quadratic equation—but they aren’t! If nothing else, breaking up problems into their smallest possible parts is good practice for what can come on a future test.
Step 1: Decide if you need to solve it
Once you’ve been given a problem, think about how long it will take to solve it. You can usually get through an easy or medium question in three minutes if you really focus. If not, then you should try and simplify it. If a difficult question still looks impossible even after simplifying it, then move on to another one. Chances are, if you can’t solve a problem within a few minutes, it won’t change in your head with more time; instead you’ll just get frustrated and waste time needlessly trying.
Step 2: Work backwards through formula's
For example, let's say you want to find out what is 2+2; step 1 is to break down each problem into its parts: 2+2=4 (using addition). Once you have your answer, solve for each part individually. Here, we will be using subtraction to solve it: 4-2=2(Using subtraction) Now that we have our answer, put it back together again. This can now be used in any problem by reversing both methods (addition and subtraction), depending on what question or situation you're trying to solve. Work backwards through formulas and try combining different concepts together in order to work out a problem from a simple model/method.
Step 3: Number dropping and substitution
Use number dropping and substitution techniques to increase your score in math. Often, students are not able to solve a problem because they know that no value lies between two given values (for example, if asked to find out x when 1<x<3 then you may realize that 0 or 2 is not a solution). You can avoid these situations by substituting other values in place of some variables. For example, suppose you have been asked to calculate 22/7 and you are confident about its value after calculating it using substitution (that is, 6). Now think of that problem as asking how many numbers less than 7 add up to 6? Obviously 4 will do (1,2,3 and 4). Then again what is 2 times 3? 6!
Step 4: Choose your own strategy of solving
Solve mentally before solving on paper. Whenever you can solve a problem mentally, do so; it saves time and effort. If a solution doesn’t come to you quickly enough, you may have overlooked something or need to clarify your thinking. Solve by cases: You can often solve a problem by dividing it into two or more separate cases and working out each one separately (and then putting them together). When doing so, pay special attention to make sure that your solutions are reasonable in all cases. Get someone else to check your work: Even if you don’t get stuck or lost during the course of a math problem, there’s value in getting someone else to take a look at what you’ve done at least once throughout your work.
Step 5: Common question
This is a common question that most CBSE board students ask at least once in their life. How can I get good marks in math? How can I become a topper in mathematics? A lot of students start panicking when they see difficult problems even after studying for hours and hours.
Step 6: Visualise your way through questions
Visualization is one of most powerful tools in your arsenal. In a test, it’s almost impossible to know for sure what you’ll see and be able to solve. But by using visualization techniques, you can come up with strategies that will help you identify patterns and correctly answer questions. For example, imagine if I were going to ask how many points are scored by football teams in a given season. Because I don’t know how many games they play, whether they lose or tie any games, or even if they win every game from start to finish, I wouldn’t have a clear way forward without more information.
