Example Problems and Solutions

Alright, let's get our hands dirty with some actual example problems from SBMPTN 2022. We'll walk through each problem step-by-step, breaking down the solution so it's crystal clear. Get your pencils ready, and let's do this!

Problem 1: Algebra Basics

Problem: If 3x + 5 = 14, what is the value of 6x - 10?

Solution:

Okay, the key here is to first solve for 'x' in the first equation. It's like finding the missing piece of a puzzle! So, let's start by isolating 'x'.

1. Subtract 5 from both sides of the equation: 3x + 5 - 5 = 14 - 5. This simplifies to 3x = 9.
2. Divide both sides by 3 to get 'x' by itself: 3x / 3 = 9 / 3. This gives us x = 3. Awesome, we found 'x'!

Now that we know x = 3, we can plug that value into the second expression, 6x - 10. Think of it as replacing 'x' with its true value.

1. Substitute x = 3 into the expression: 6(3) - 10.
2. Multiply 6 by 3: 18 - 10.
3. Subtract 10 from 18: 18 - 10 = 8.

So, the value of 6x - 10 is 8. And that's our final answer! See? Algebra isn't so scary after all!

Problem 2: Geometry Fundamentals

Problem: A rectangle has a length of 12 cm and a width of 5 cm. What is the area of the rectangle?

Solution:

Geometry time! Remember those shapes from elementary school? Well, they're back to help us out! To find the area of a rectangle, we use a simple formula: Area = length × width. It's like finding out how much space the rectangle covers.

1. Identify the length and width: Length = 12 cm, Width = 5 cm.
2. Multiply the length and width: Area = 12 cm × 5 cm.
3. Calculate the result: Area = 60 square cm.

Therefore, the area of the rectangle is 60 square centimeters. Easy peasy, right? Knowing your formulas is half the battle in geometry!

Problem 3: Arithmetic Adventures

Problem: What is 25% of 80?

Solution:

Let's tackle some percentages! Percentages can seem tricky, but they're just fractions in disguise. To find 25% of 80, we need to convert the percentage into a decimal or fraction. Think of it as finding a portion of the whole.

1. Convert 25% to a decimal: 25% = 25 / 100 = 0.25. Another way is convert 25% to a fraction: 25% = 1/4.
2. Multiply the decimal by 80: 0.25 × 80 = 20. If we use fraction, then we divide 80 by 4: 80/4 = 20

So, 25% of 80 is 20. That wasn't so bad, was it? With a little practice, you'll be calculating percentages in your sleep!

Tips and Tricks for Solving Basic Math Problems

Okay, now that we've tackled some example problems, let's arm you with some killer tips and tricks to solve basic math problems even faster and more accurately. These are like cheat codes for your brain! Remember, practice makes perfect, so the more you use these strategies, the better you'll get.

Read the Problem Carefully

This might seem obvious, but it's super important. Before you even think about solving anything, take a moment to read the problem carefully. Understand what the question is asking and what information you have. Highlight key words and numbers. It's like being a detective and gathering all the clues before solving a mystery! Pay attention to details like units of measurement and any specific conditions or constraints mentioned in the problem. A clear understanding of the problem is the first step to finding the correct solution. Sometimes, a simple misreading can lead to a completely wrong answer. So, take your time, read carefully, and make sure you know exactly what you're being asked to solve. It's better to spend a few extra seconds understanding the problem than to rush into solving the wrong thing.

Break Down Complex Problems

Sometimes, a problem might look intimidating at first glance. But don't panic! The trick is to break it down into smaller, more manageable steps. It's like eating an elephant – you can't do it in one bite! Identify the different parts of the problem and solve each part separately. Then, combine the results to get the final answer. This approach makes the problem less overwhelming and easier to handle. Look for patterns and relationships between the different parts of the problem. This can help you simplify the problem and find a more efficient solution. By breaking down complex problems into smaller steps, you'll be able to tackle even the most challenging questions with confidence.

Use Estimation

Estimation can be a powerful tool for checking your answers and catching mistakes. Before you start calculating, take a moment to estimate what the answer should be. This will give you a ballpark figure to compare your final answer to. If your calculated answer is way off from your estimate, you know something went wrong and you need to double-check your work. Estimation can also help you eliminate answer choices on multiple-choice questions. If you can quickly estimate the answer and rule out obviously wrong options, you'll increase your chances of choosing the correct answer. So, don't underestimate the power of estimation! It's a valuable skill that can save you time and improve your accuracy.

Practice Regularly

This is the golden rule of math! The more you practice, the better you'll become. Set aside some time each day to work on math problems. Focus on the areas where you're struggling. Use practice tests and sample questions to simulate the actual exam environment. The more you expose yourself to different types of problems, the more comfortable and confident you'll become. Practice not only reinforces your understanding of the concepts but also helps you develop problem-solving skills and improve your speed and accuracy. So, make practice a regular part of your study routine and watch your math skills soar!

Common Mistakes to Avoid

Nobody's perfect, and we all make mistakes. But knowing the common pitfalls can help you avoid them on the SBMPTN. Let's shine a spotlight on some frequent errors students make so you can steer clear of them!

Careless Calculation Errors

This is a big one! Even if you understand the concepts, a simple arithmetic mistake can cost you points. Double-check your calculations, especially when dealing with decimals, fractions, and negative numbers. It's like proofreading your writing – you want to catch those typos before submitting your work! Use a calculator when appropriate, but don't rely on it blindly. Make sure you understand the calculations you're performing and that you're entering the numbers correctly. A little extra attention to detail can make a big difference in your score.

Misreading the Question

We talked about this earlier, but it's worth repeating. Misreading the question is a common mistake that can lead to completely wrong answers. Take your time to read the question carefully and make sure you understand what you're being asked to solve. Highlight key words and numbers. If necessary, rephrase the question in your own words to make sure you understand it correctly. It's better to spend a few extra seconds understanding the question than to rush into solving the wrong thing.

Forgetting Units

Units of measurement are important! Don't forget to include the correct units in your answers. If the problem asks for the area in square centimeters, make sure your answer is in square centimeters, not just centimeters. Pay attention to the units given in the problem and make sure your answer is consistent with those units. A missing or incorrect unit can cost you points, even if your calculations are correct. So, always double-check your units before submitting your answer.

Not Showing Your Work

Even if you can solve a problem in your head, it's always a good idea to show your work. This allows you to track your steps and catch any mistakes you might have made. It also makes it easier for the examiner to understand your reasoning and give you partial credit, even if your final answer is incorrect. Showing your work demonstrates your understanding of the problem-solving process and allows you to learn from your mistakes. So, always take the time to write out your steps, even if you think you can solve the problem without doing so.
