Step-by-Step Solution

Multiplication: 2.56 * 1.9

Alright, first things first, we gotta tackle the multiplication part: 2.56 * 1.9. When multiplying decimals, it's really helpful to treat them as whole numbers first. So, let's imagine we're multiplying 256 by 19. If you do this multiplication, you'll get 4864. Now comes the important part, guys – placing the decimal point. Count how many digits are after the decimal points in both of the original numbers. In 2.56, there are two digits after the decimal, and in 1.9, there's one. That’s a total of three digits. So, in our answer, we need to place the decimal point so there are three digits after it. That means our answer for 2.56 * 1.9 is 4.864. This step is super crucial; it ensures we're working with the right values. Keep in mind, the position of the decimal point determines the value of the number, so make sure you place it carefully. We are one step closer to figuring out the answer to the whole equation. Remember, it's all about practice and understanding the process. Now we're going to proceed with the next step, but before we move on, make sure you understand the multiplication part well, as this is the cornerstone of our equation. It is very important to get this part right, and the rest will be a piece of cake.

Addition: 4.864 + 5.4

Okay, now that we've got the multiplication done, let's move on to the addition. We'll add 5.4 to the result we just got, which is 4.864. When adding decimals, the key is to line up the decimal points. So, we'll write it like this to make it super easy: 4.864 + 5.400. Yes, adding those extra zeros doesn't change the value of 5.4, but it sure does make the addition easier, right? When you add those numbers, you get 10.264. That’s the sum of 4.864 and 5.4. This is a very important step as well, because we are using the answer from the first step to do the second step. If the first step is wrong, this step will also be wrong. That’s why we need to focus on each step and make sure it’s correct. I know it can be a bit tricky with all those decimal places, but trust me, with a little practice, it’ll become second nature. Remember to always keep your decimal points aligned. This is another important step, and we are almost at the end of solving the equation! We’re making some good progress, guys!

Subtraction: 10.264 - 2.8

Now for the final step: subtraction! We've got 10.264 and we need to subtract 2.8 from it. Again, let's line up those decimal points like so: 10.264 - 2.800. This gives us 7.464. And there you have it, folks! That's the solution to the entire equation. We've gone from multiplication to addition, and finally to subtraction, and we've done it step-by-step. It wasn't that hard, was it? The secret is to keep everything organized and pay attention to those decimal points. See? Math can be fun! This subtraction part is the final piece of the puzzle. Now, we've completed all the operations, so we just have to make sure we didn’t make any mistakes. We need to go back and check our work, maybe using a calculator. But as long as we followed the steps, we should be fine. Great job on sticking with it! This proves that you can tackle these math problems if you follow the right steps. Now you know how to do these kinds of problems. Remember, the key is to stay organized and patient!

Final Answer

So, the answer to the equation 2.56 * 1.9 + 5.4 - 2.8 = 7.464!

Tips and Tricks
