We are going to address various problems, including those involving addition, subtraction, and a mix of operations. The goal is to make sure you understand the 'why' behind each step, not just the 'how.'

Solving the Math Problems Step by Step

5 + 35

Alright, first up: 5 + 35. This one is pretty straightforward, right? When we add 5 to 35, we get 40. Simple as that! This is a fundamental addition problem that helps build the foundation for more complex calculations. We start by combining two numbers to find their total. In this case, we're adding two positive integers, meaning we move forward on the number line. The concept is based on counting and combining sets. Imagine having 5 apples and getting 35 more; now, you have a total of 40 apples. This simple addition is used everywhere, from counting money to calculating distances.

So, 5 + 35 = 40. It's always a good idea to double-check your work, especially when you're just starting out. You can use a calculator to make sure you've got the correct answer, but don't get too reliant on the calculator. Doing these simple calculations in your head helps improve your mental math skills, making it easier to solve more difficult problems in the future. Remember, practice makes perfect! Try coming up with your own addition problems and solving them. The more you practice, the faster and more comfortable you'll become with these types of calculations.

+5 - 9

Next up: +5 - 9. This is where we start to get into some subtraction with positive and negative numbers. We start with 5 and subtract 9 from it. Think of it like this: you have 5 dollars but you owe 9 dollars. You're going to end up owing some money! The result is -4. So, +5 - 9 = -4. With this equation, we are not just subtracting, but we're also dealing with negative numbers. This concept can be visualized on a number line, where we start at the point +5 and move 9 units to the left. Remember, subtracting a larger number from a smaller number results in a negative value. So, if you were to visualize the number line, you'd start at 5 and go back 9 places, landing on -4. It helps to think about it in terms of money, debts, or temperature – anything that goes above and below zero. When we understand and practice these concepts, we become more skilled at solving complex mathematical problems. Furthermore, practicing these types of problems develops strong analytical thinking skills.

+ -10 - 8 - 18

Now, let's look at: -10 - 8 - 18. Here, we're subtracting multiple numbers. The trick is to just add them all up as if they're negative. So, -10 minus 8 is -18. Then, -18 minus 18 is -36. Therefore, -10 - 8 - 18 = -36. So in this calculation, we're simply adding more negative numbers together. We can combine all the negative numbers, which gives us the final answer. These calculations are straightforward, but they are crucial for solving complex calculations. We can easily visualize this process using a number line, starting from zero, and moving to the left, which signifies the negative direction. Think of these negative numbers like debts or losses. Each number represents an additional debt or loss, and when you add them all together, you find the total debt or loss. These problems help strengthen our mathematical thinking. These problems are also useful in real-world scenarios, such as managing finances. If you owe various amounts, these calculations can help you find out your total debt.

20 - 5 = ?

Next up: 20 - 5. This one is pretty simple. When we subtract 5 from 20, we get 15. So, 20 - 5 = 15. Another basic subtraction problem. You start with a quantity and take some away. This is one of the most basic mathematical operations. This problem is another great way to practice subtraction. This can be understood using physical objects. For example, if you have 20 candies and you eat 5, you have 15 candies left. This process builds a strong foundation in arithmetic. The more you practice, the quicker and more accurate your calculations will be. This also teaches a sense of quantity and helps with money management. These kinds of calculations are also very useful in everyday life. For instance, when you're calculating change. By understanding these concepts, you can easily handle real-world challenges.

s

This is just a variable. This is not a math operation, so it has no numerical value. Variables are used in mathematical equations to represent a value that can change or is unknown. So, since it is a variable, there is no numerical answer to be found here.

30 + 5 = 35

Here we go: 30 + 5 = 35. Another addition problem, but this time we have a larger number. When we add 5 to 30, we get 35. This is pretty direct, like our first example. This reinforces the concept of addition. This teaches us how to add single-digit numbers to larger numbers. This is a common operation. This equation is the foundation for various calculations. We encounter addition almost every day. It's used in counting money, calculating distances, and much more. This is an important calculation for everyday life.

35 / 1

Now, let's talk about 35 / 1. This is a division problem. Whenever you divide any number by 1, you always get the same number. So, 35 / 1 = 35. So in this case, the number 35 divided by 1 is still 35. You're not changing the value, you're just saying how many times 1 goes into 35. If you have 35 of something and you split it into groups of 1, you still have 35 groups. This concept is simple yet fundamental in understanding mathematical division. We are basically looking at how many times 1 can fit in 35. This is a core concept and is a stepping stone to more complex calculations. We also encounter this type of calculation in real-world scenarios. We see division in almost everything we do, from cooking to managing finances.

-6 - 4 10

Let's break down: -6 - 4 10. This problem is a little tricky because it looks like it's a mix of subtraction and a standalone number. We'll assume it's -6 - 4 + 10. If we follow the order of operations, we add and subtract from left to right. -6 minus 4 is -10. Then, -10 plus 10 is 0. So, -6 - 4 + 10 = 0. This involves both subtraction and addition with negative and positive numbers. When we approach calculations like these, it is important to pay close attention to the signs. This problem strengthens our understanding of the order of operations. This problem provides a great exercise for working with both negative and positive numbers. This type of practice helps increase our overall mathematical skills. This problem is perfect for testing your understanding of basic arithmetic.

75 to 8 - 68

Finally, the problem is 75 - 8 - 68. We can solve this step by step. First, subtract 8 from 75, which gives you 67. Then, subtract 68 from 67. You'll get -1. So, 75 - 8 - 68 = -1. This is a basic subtraction problem, although, we do get a negative number as our answer. This problem provides more practice in subtraction. This type of problem also helps us get comfortable with subtracting numbers and with negative numbers. This is a key example of how you can end up with a negative number. This builds our understanding of number lines. This concept is useful in various real-world situations, such as managing your bank account.
