Hello, I need someone to check my work and tell me what I did wrong please. I am in 8th grade for the 3rd time in a row starting this school year and I have been issued to do 6th grade math since that is the subject I am falling hard on, everything else I am good with. I will post a picture in the area below

The right answer is on the calculator, but I did not come up with that answer. I was very close though. I counted 5 for the decimal placement and I do not know where the 0 at the ends goes. I'd be very thankful if someone could explain to me what steps I missed or did wrong.
Not the answer you are looking for? Search for more explanations.
Thank you =)
So whats the problem?
The problem is
What is the product of 8.0425 × 2.6?
20.9105...Would you like me to explain how?
Yes please. I know I either messed up a step or missed one, I was so close to the right answer.
You need to place them in the right place value first.
You did both steps of the multiplication, and the addition correctly.
The only mistake you made was placing the decimal point.
@mathstudent55 I figured that was it. I learned that you count the number of spaces, so in this case 8.0425 = 4 spaces, 2.6 = 1 space. So I'd move the decimal 5 spaces over in the problem, that's how I got 2.091050
Wait wait wait, hold on. I dropped the 0 because I thought you had to do that, that's how I got my answer I believe
This is what you have before placing the decimal point.
All you did was place the decimal wrong. Just like what he said
You can't drop zeros before you write the decimal point.
Thank you both =) I really need to brush up on my math skills. Thank you very much @mathstudent55
Since the answer is 20.91050, and a zero at the far right at the end of a number after a decimal point is not necessary, then you can write the answer as 20.9105, just like the calculator in your picture shows.
Got it! I'm happy I found this website, so many nice people here.
