USP Admissions: Students In Other Courses Calculation

Hey guys! Let's break down this math problem about university admissions. We've got a scenario at the University of São Paulo (USP) where a bunch of students got accepted, and we need to figure out how many landed in courses other than the ones specifically listed. It's like a real-world puzzle, and we're going to solve it together.

Understanding the Problem

So, here's the deal: USP had 2,530 students get the thumbs up for admission. That's the total pie. Now, we know some slices of that pie:

• 380 are heading to Medicine.
• 450 are geared up for Civil Engineering.
• 812 are diving into Letters (which could be literature, languages, and all sorts of cool stuff!).
• 830 are off to study Law.

Our mission, should we choose to accept it (and we do!), is to find out how many students make up the rest of the pie – those who got into courses besides these four. Think about it: USP offers tons of programs, from biology to economics to art history. We need to figure out how many students are in those other fields.

To tackle this, we're going to use some good ol' basic math. It's all about addition and subtraction, so don't worry, no crazy calculus here! We'll add up the students in the known courses, and then subtract that total from the overall number of admitted students. This will leave us with the number of students in the "other" courses. It's like taking a whole pizza, removing the slices we know about, and seeing what's left.

Step-by-Step Solution

Okay, let's get down to business. First, we need to figure out the total number of students admitted into Medicine, Civil Engineering, Letters, and Law. This is where our addition skills come in handy. We're going to add these numbers together:

380 (Medicine) + 450 (Civil Engineering) + 812 (Letters) + 830 (Law) = ?

Let's break it down to make it super clear. We can start by adding the hundreds:

300 + 400 + 800 + 800 = 2300

Then, let's add the tens:

80 + 50 + 10 + 30 = 170

Finally, we add the ones (in this case, just the 2 from 812):

0 + 0 + 2 + 0 = 2

Now, let's put it all together:

2300 + 170 + 2 = 2472

So, a grand total of 2,472 students were admitted into those four specific courses. We're one step closer to solving the puzzle!

Now comes the final piece: subtraction. Remember, we know that 2,530 students were admitted in total. We also know that 2,472 of them are in Medicine, Civil Engineering, Letters, or Law. To find out how many are in other courses, we subtract the smaller number from the larger one:

2530 (Total Students) - 2472 (Students in Specified Courses) = ?

Let's do the subtraction. This might require a little borrowing, so pay close attention. We start with the ones place:

0 - 2

We can't subtract 2 from 0, so we need to borrow 1 from the tens place. This turns the 3 in the tens place into a 2, and the 0 in the ones place into a 10. Now we have:

10 - 2 = 8

Moving to the tens place, we now have:

2 - 7

Again, we can't subtract 7 from 2, so we borrow 1 from the hundreds place. The 5 in the hundreds place becomes a 4, and the 2 in the tens place becomes a 12. Now we have:

12 - 7 = 5

In the hundreds place, we have:

4 - 4 = 0

And finally, in the thousands place:

2 - 2 = 0

Putting it all together, we get:

2530 - 2472 = 58

The Answer!

Alright, drumroll please... the answer is 58! That means there are 58 students who were approved for courses other than Medicine, Civil Engineering, Letters, and Law at USP. We did it!

Why This Matters

This kind of problem-solving isn't just about numbers; it's about critical thinking. It's about taking a big chunk of information, breaking it down into smaller, manageable pieces, and then putting those pieces back together to find the solution. This is a skill that's super useful in all sorts of situations, not just in math class.

Think about it: when you're planning a trip, you need to figure out your budget, your transportation, your accommodation, and all sorts of other details. That's problem-solving! When you're working on a group project, you need to figure out how to divide the tasks, how to communicate effectively, and how to overcome any obstacles that come your way. That's problem-solving too!

So, by practicing these kinds of math problems, you're not just learning how to add and subtract; you're learning how to think logically, how to organize information, and how to find solutions. These are skills that will help you succeed in school, in your career, and in life in general.

Real-World Applications

This type of problem has real-world applications beyond just university admissions. Imagine you're a business owner trying to figure out where your customers are coming from. You might know that a certain percentage are coming from online ads, another percentage from word-of-mouth, and another percentage from social media. To figure out how many are coming from other sources, you'd use the same kind of math we used here: add up the known sources, and subtract that from the total.

Or, think about a city planner trying to allocate resources. They might know how many people are using public transportation, how many are driving cars, and how many are biking. To figure out how many are using other modes of transportation (like walking or scooters), they'd use the same subtraction method.

The point is, these basic math skills are the building blocks for all sorts of more complex calculations and decisions. By mastering them now, you're setting yourself up for success in the future.

Practice Makes Perfect

So, what's the best way to get better at these kinds of problems? Practice, practice, practice! The more you work with numbers and break down problems, the easier it will become.

Try finding similar problems online or in textbooks. You can also create your own problems! Think about situations in your own life where you need to figure out a total and then subtract some known quantities. The more you practice, the more confident you'll become.

Conclusion

We've successfully solved the USP admissions problem, and hopefully, you've gained a better understanding of how to tackle similar challenges. Remember, it's all about breaking down the problem into smaller steps, using the right operations (in this case, addition and subtraction), and carefully working through each step.

Math can be fun, especially when you see how it connects to the real world. Keep practicing, keep asking questions, and keep challenging yourself. You've got this!
