We'll be solving several examples, breaking down each step to make sure you understand the process. Trust me, it's easier than it looks, and we'll get through this together. Let's make math exciting, one problem at a time. So, grab your notebooks, and let's get started. Get ready to boost your math skills. This is the first step towards math mastery. Are you ready? Let's go!
Understanding the '*' Operation
Alright, before we jump into the problems, let's make sure we're all on the same page. The operation '' is defined as follows: a * b = ab + ab/3. This means when you see 'a * b', you need to multiply 'a' and 'b' together (that's 'ab'), and then add one-third of that result to itself. Think of it as a special kind of multiplication where we give ourselves a little bonus. This is important: always follow the order of operations (PEMDAS/BODMAS) to get the correct answer. You wouldn't want to add before you multiply! Make sure you grasp the definition before we move on. Take a moment to understand it. Let’s make sure we're solid on what this operation actually means. This is the foundation for everything we're about to do. Understanding the core concept is key to solving the problems correctly. Always remember to apply the formula correctly, and you will do great. If you take the time to truly grasp this concept, everything else will fall into place. Understanding the rule of the '' operation is the key to solving these problems. It's the secret sauce that unlocks all the answers. So, take your time, review the formula, and make sure you're comfortable with it. Ready to move on? Let's start with our first example.
A. Calculating 2 * 3
Now, let's get down to business with our first example: 2 * 3. Following our definition, we know that a = 2 and b = 3. First, we need to calculate ab, which is 2 multiplied by 3. This gives us 6. Next, we need to find one-third of ab. That means we take 6 and divide it by 3, which equals 2. Finally, we add these two results together: 6 + 2 = 8. So, 2 * 3 = 8. Pretty simple, right? See, this isn't so bad after all. Just follow the steps, and you'll nail it every time. Just plug in the values and follow the process. Don't worry, we'll go through more examples to make sure you understand every aspect. We're going to continue with more examples. Get ready to see how it all comes together! The first step is to correctly identify the values of a and b. Then, follow the given formula to calculate the result. This may seem complex initially, but it will become easy when you practice it repeatedly. Remember, practice is essential to master this concept. Keep going! Let's move on to the next one and keep the momentum going!
Step-by-step Breakdown
- Identify a and b: In 2 * 3, a = 2 and b = 3.
- Calculate ab: 2 * 3 = 6.
- Calculate ab/3: 6 / 3 = 2.
- Add the results: 6 + 2 = 8. Therefore, 2 * 3 = 8. This is the final result. Keep the method in mind as we will use it over and over again.
B. Calculating 4 * 5
Okay, let's try another one: 4 * 5. This time, a = 4 and b = 5. First, calculate ab: 4 multiplied by 5 equals 20. Next, find one-third of 20, which is 20/3 (or approximately 6.67 if you prefer the decimal form). Finally, add these two results: 20 + 20/3 = 20 + 6.67 = 26.67. Therefore, 4 * 5 = 26.67. This demonstrates that calculations can sometimes result in fractions, which is perfectly normal in mathematics. Take a look at the calculation, and be sure that you grasp all the steps. Now, it's starting to become fun, right? Remember, the key is to apply the formula correctly. Make sure you're comfortable with both fractions and decimals, as they can pop up in these problems. There's no reason to be intimidated. So, let's keep the ball rolling. Ready for the next one? Let's go.
Step-by-step Breakdown
- Identify a and b: In 4 * 5, a = 4 and b = 5.
- Calculate ab: 4 * 5 = 20.
- Calculate ab/3: 20 / 3 = 6.67 (approximately).
- Add the results: 20 + 6.67 = 26.67. Therefore, 4 * 5 = 26.67. Now, it's time to test your skills.
C. Calculating -2 * 4
Now, let's see what happens when we throw in some negative numbers. We're calculating -2 * 4. Remember, our formula still applies! Here, a = -2 and b = 4. First, we calculate ab: -2 multiplied by 4 equals -8. Next, we find one-third of -8, which is -8/3 (or approximately -2.67). Finally, add these two results: -8 + (-8/3) = -8 - 2.67 = -10.67. Therefore, -2 * 4 = -10.67. Dealing with negative numbers is just as easy! Just keep track of those signs, and you'll be fine. Don't let the negative signs scare you. Be confident! It's important to remember the rules of multiplying and adding negative numbers. You've got this, and you're doing a fantastic job. Keep practicing, and you'll master these types of problems in no time. So, let’s keep moving!
Step-by-step Breakdown
- Identify a and b: In -2 * 4, a = -2 and b = 4.
- Calculate ab: -2 * 4 = -8.
- Calculate ab/3: -8 / 3 = -2.67 (approximately).
- Add the results: -8 + (-2.67) = -10.67. Therefore, -2 * 4 = -10.67. You are doing well. Let's move forward.
D. Calculating 1/2 * 2/3
Alright, let's tackle a problem with fractions: 1/2 * 2/3. Here, a = 1/2 and b = 2/3. First, calculate ab: (1/2) multiplied by (2/3) equals 2/6, which simplifies to 1/3. Next, find one-third of 1/3: (1/3) / 3 = 1/9. Finally, add these two results: 1/3 + 1/9 = 3/9 + 1/9 = 4/9. Therefore, 1/2 * 2/3 = 4/9. Fractions might seem intimidating, but the process is exactly the same! Just remember the rules for multiplying and adding fractions. You're becoming a math whiz. You're on a roll! Keep it up. Now, isn't math exciting? Don't worry, fractions and decimals are your friends. The key is to apply the formula correctly.
Step-by-step Breakdown
- Identify a and b: In 1/2 * 2/3, a = 1/2 and b = 2/3.
- Calculate ab: (1/2) * (2/3) = 1/3.
- Calculate ab/3: (1/3) / 3 = 1/9.
- Add the results: 1/3 + 1/9 = 4/9. Therefore, 1/2 * 2/3 = 4/9. This is the last example; you are almost done!
E. Calculating 3/4 * 7
Finally, let's calculate 3/4 * 7. Here, a = 3/4 and b = 7. First, calculate ab: (3/4) * 7 = 21/4, which is 5.25. Next, find one-third of 21/4: (21/4) / 3 = 21/12, which simplifies to 7/4 or 1.75. Finally, add these two results: 21/4 + 7/4 = 28/4 = 7. Therefore, 3/4 * 7 = 7. We've made it to the last example. Remember, practice makes perfect. Try these problems again on your own to solidify your understanding. You are doing a fantastic job. You've now seen how to solve various problems using this '*' operation. The more you practice, the easier it becomes. Keep up the good work! We’ve reached the end. Give yourself a pat on the back. You are a math champion! The main thing is that you keep learning and having fun.
Step-by-step Breakdown
- Identify a and b: In 3/4 * 7, a = 3/4 and b = 7.
- Calculate ab: (3/4) * 7 = 21/4 = 5.25.
- Calculate ab/3: (21/4) / 3 = 7/4 = 1.75.
- Add the results: 21/4 + 7/4 = 28/4 = 7. Therefore, 3/4 * 7 = 7. Congratulations! You've successfully solved all the problems.
