Use of Latex

I am having problem with this one.
I want it to appear exactly like the one in the picture. What am I supposed to do that I didn't do well?
[math]\begin{array}{|l|r|} \text{No.} & \text{Log} \\ \hline 13.95 & 1.1446 \\ 364 & + 2.5611 \\ \overline{3.7057} \\ \hline 4.32 & 0.6355 \\ \hline 1176 & 3.0702 \\ \hline \end{array} [/math]

A big part of coding is debugging your own code. Give that a try.

In the first row of numbers, 1.1446 appears in the right column. What caused that to happen? Look at the code for that line.
 
Sorry, I have been shown this before. I forget that am supposed to use ~ for the empty space at the left. Thanks for the gentle reminder. I now remember.

That's okay, but not necessary. The issue was that you'd forgotten to type the & in that row. It's the & that separates the coding into columns.

Waou! That's another truth.
[math]\begin{array}{|l|r|} \text{No.} & \text{Log} \\ \hline 13.95 & 1.1446 \\ 364 & + 2.5611 \\ & \overline{3.7057} \\ \hline 4.32 & 0.6355 \\ \hline 1176 & 3.0702 \\ \hline \end{array} [/math]
 
I forgot to point out a typo in your chart.

log(1176) = 3.0704

correct to four decimal places

;)

Not really. That is negligible. The difference between the logs is just 0.0002. log(1176) = 3.0704 is just an approximation because the solution to [imath]\frac{13.95×364}{4.32}[/imath] is 1175.416667...... So you can see that is an approximation of 1176 as a result of the workings in the table. So it doesn't really matter.
Moreover my main aim of creating this thread is to be guided on how to write the expressions in Latex. Anyway thanks for your observation.

Ah, I can see it now that you've explained the reasoning behind the chart. Perhaps, the 1176 ought to be 1175.4 ;)

Also, we do not use ellipsis dots after a rounded number because those digits were thrown away after rounding.

We could use ellipsis dots to show repeating 6s, like this: 1175.416666…

Alternatively, we may write a repeating decimal number by placing a bar over the repeating part:

\(\displaystyle \frac{13.95×364}{4.32} = 1175.41\overline{6}\)

Cheers :)

Thanks.
 
Hi. Are you now asking for math help? There's a list of exercises (with the word "help") that keeps disappearing and reappearing! o_O

[imath]\;[/imath]
 
Not yet sir. I am preparing a homework help thread that involves a lot of Latex work. So am showing what I know about the problems, where am stuck and where I need help.
Let it not be that I am just looking for someone to do my homework.
But first of all, I need to debug it to ensure that the intended thread appears. That's why the post is appearing and disappearing.
Am not done yet. When am done, I will post it as a new thread in a new section or heading. Thanks.

Hello. The forum provides a Preview button. You may use it to check your typing, without having to repeatedly post and delete the thread (if that's what you've been doing). The forum software also saves your typing, so that it will reload into the post-reply field the next time you access the thread. Each time the system saves your typing, a small, green dot appears on the Drafts icon (which is located to the left of the Preview button). Members may also manually save or delete a draft post, by clicking the Drafts icon for the drop-down menu. Sometimes (for reassurance), I will also save my typing to a local text file using manual copy-and-paste, after having first toggled BB code.

I have seen it. Thank you.
What if I want to save my work as draft maybe because I couldn't finish, where can I find the draft button?
