Let's dive into these numerical expressions! When we see something like 13 x 58 x 4, 32 x 26 x 2, and 52 x 10, it's all about understanding multiplication and how to break down these calculations to make them easier to manage. These expressions might seem random, but they're all about practicing our arithmetic skills and finding different ways to arrive at a solution. So, grab your calculators (or your mental math skills) and let’s get started!

Understanding the Basics of Multiplication

Before we tackle the specific examples, let's quickly recap the basics of multiplication. Multiplication is a fundamental arithmetic operation that represents repeated addition. For example, 3 x 4 means adding 3 to itself 4 times (3 + 3 + 3 + 3), which equals 12. Understanding this basic principle is crucial for more complex calculations. When you see a multiplication problem, think of it as a shortcut for adding the same number multiple times.

Multiplication also has some handy properties that can make calculations easier. The commutative property states that the order of the numbers doesn't matter. So, a x b is the same as b x a. For instance, 2 x 3 is the same as 3 x 2, both equaling 6. The associative property allows you to group numbers differently when multiplying more than two numbers. So, (a x b) x c is the same as a x (b x c). For example, (2 x 3) x 4 is the same as 2 x (3 x 4), both equaling 24. These properties are super useful when dealing with larger numbers!

Moreover, understanding place value is essential. When multiplying larger numbers, breaking them down into tens, hundreds, and so on can simplify the process. For example, to multiply 25 x 10, you can think of it as (20 + 5) x 10, which is 20 x 10 + 5 x 10, resulting in 200 + 50 = 250. Knowing these basics sets the stage for tackling more complex multiplication problems.

Breaking Down 13 x 58 x 4

Okay, let's start with the first expression: 13 x 58 x 4. At first glance, it might look a bit intimidating, but we can break it down into manageable steps. One approach is to start by multiplying the first two numbers, and then multiply the result by the third number. Alternatively, we can use the associative property to rearrange the order and group the numbers differently. Let’s explore both methods.

Method 1: Multiplying in Order

First, let's multiply 13 x 58. This can be a bit tricky to do mentally, so let’s break it down further. We can think of 13 as (10 + 3). So, 13 x 58 becomes (10 x 58) + (3 x 58). Now, 10 x 58 is easy: it’s just 580. For 3 x 58, we can calculate it as 3 x (50 + 8), which is (3 x 50) + (3 x 8) = 150 + 24 = 174. Adding these together, we get 580 + 174 = 754. So, 13 x 58 = 754.

Now we need to multiply 754 x 4. Again, we can break this down. Think of 754 as (700 + 50 + 4). So, 754 x 4 is (700 x 4) + (50 x 4) + (4 x 4), which is 2800 + 200 + 16 = 3016. Therefore, 13 x 58 x 4 = 3016.

Method 2: Rearranging the Order

Another approach is to rearrange the order using the associative property. We can rewrite 13 x 58 x 4 as 13 x (58 x 4). Let's first calculate 58 x 4. We can think of 58 as (50 + 8), so 58 x 4 becomes (50 x 4) + (8 x 4), which is 200 + 32 = 232. Now we have 13 x 232.

To calculate 13 x 232, we can break it down again. Think of 13 as (10 + 3). So, 13 x 232 becomes (10 x 232) + (3 x 232). Now, 10 x 232 is simply 2320. For 3 x 232, we can calculate it as 3 x (200 + 30 + 2), which is (3 x 200) + (3 x 30) + (3 x 2) = 600 + 90 + 6 = 696. Adding these together, we get 2320 + 696 = 3016. So, 13 x 58 x 4 = 3016. As you can see, both methods give us the same answer!

Breaking Down 32 x 26 x 2

Next up, we have 32 x 26 x 2. This expression can also be tackled in multiple ways. Let’s explore multiplying in order and rearranging the order to see which method works best for us.

Method 1: Multiplying in Order

First, let's multiply 32 x 26. To make this easier, we can break down both numbers. Think of 32 as (30 + 2) and 26 as (20 + 6). So, 32 x 26 becomes (30 x 20) + (30 x 6) + (2 x 20) + (2 x 6), which is 600 + 180 + 40 + 12 = 832. Therefore, 32 x 26 = 832.

Now we need to multiply 832 x 2. This is relatively straightforward. 832 x 2 is (800 x 2) + (30 x 2) + (2 x 2), which is 1600 + 60 + 4 = 1664. So, 32 x 26 x 2 = 1664.

Method 2: Rearranging the Order

Alternatively, we can rearrange the order to simplify the calculation. Notice that multiplying by 2 is often easier. So, let’s rewrite 32 x 26 x 2 as 32 x (26 x 2). First, we calculate 26 x 2, which is 52. Now we have 32 x 52.

To calculate 32 x 52, we can break down both numbers again. Think of 32 as (30 + 2) and 52 as (50 + 2). So, 32 x 52 becomes (30 x 50) + (30 x 2) + (2 x 50) + (2 x 2), which is 1500 + 60 + 100 + 4 = 1664. Thus, 32 x 26 x 2 = 1664. Again, both methods yield the same result!

Breaking Down 52 x 10

Finally, let's tackle the expression 52 x 10. This one is much simpler than the previous examples. Multiplying by 10 is one of the easiest operations in arithmetic. When you multiply any number by 10, you simply add a zero to the end of the number. So, 52 x 10 = 520.

The reason this works is due to our base-10 number system. Multiplying by 10 shifts each digit one place to the left, effectively increasing the value of each digit by a factor of 10. The ones place becomes the tens place, the tens place becomes the hundreds place, and so on. So, when you multiply 52 by 10, the 5 (which represents 50) becomes 500, and the 2 (which represents 2) becomes 20, giving you 520.

This simple trick applies to any number. For example, 123 x 10 = 1230, 45 x 10 = 450, and so on. Understanding this makes these calculations quick and easy, saving you time and effort. In summary, 52 x 10 = 520.
