| Oct 28, 2021 at 15:06 | comment | added | user110391 | Aha, I see. I completely misunderstood. I thought "crtl dollarsign" was a command, which was supposed to be written "crtl$", not that I was supposed to press control, shift and the 4th key. It now works for me. | |
| Oct 28, 2021 at 1:27 | comment | added | Nasser | @user110391 There was no actual error when using the \floor command, but it does not render correctly. it produce wrong output. As for ctrl dollar, to enter this, need to press the CTRL SHIFT 4 keys at same time. The dollar is on the 4 key on standard keyboard. | |

| Oct 28, 2021 at 1:24 | comment | added | user110391 | I see, the issues lies with the floor function. Thanks :) I'll be accepting your answer now. Maybe you could somehow include the fact that it was the floor function messing things up in your answer? Also, this issue with the "ctrl$" command, was that caused by me having a different version than you? Maybe the 12.3 version doesn't have this command? | |
| Oct 28, 2021 at 1:05 | comment | added | Nasser | @user110391 I just tried it. Mathematica does not understand the latex command \floor. Looks like a bug. This is all new stuff and will have bugs in it. So basically try not to use these commands in your Input Latex for now. As for your sigma function solving, I suggest you make separate question on that, not related to Latex at all and keep it all using Mathematica code. Else this is getting confusing to have it all here with the latex issues involved. | |
| Oct 28, 2021 at 0:45 | comment | added | user110391 | What happened in the video happened for me as well, but only when I used the method of selecting "Inline TeX Input", it didn't work when I used the short cut "ctrl dollarsign". However, the process involving "Inline TeX Input" failed when using the other expression (the one featured at the top) $$\sum_{j=0}^{\lfloor \frac ab \rfloor} j$$ Also, how does one make mathematica solve the sigma function? The simple one with 3 as the max index value was displayed, but no output was given (i.e. the sum of sigma function). | |

| Oct 28, 2021 at 0:32 | comment | added | Nasser | @user110391 I do not know why it is not working for you. Will add a small video. | |
| Oct 28, 2021 at 0:30 | comment | added | user110391 | Using the "Inline TeX Input" was what I did to begin with, but it didn't work. The screenshots taken are from me writing LaTeX code in the window that appeared after pressing the "Inline TeX Input" option. | |
| Oct 28, 2021 at 0:27 | comment | added | Nasser | @user110391 OK, that will also work. Now just type the Latex there, in the small window that show up now, without that ctrl dollar. The ctrl dollar is just a short cut for inline Tex Input btw, you do not type ctrl with dollar, you need to press the keyboard keys CTRL$ at same time. | |
| Oct 28, 2021 at 0:26 | comment | added | user110391 | I'm using v. 12.3. This window does not appear when I type "ctrl$" in, but that window does show up when I choose "Inline TeX Input". If my further attempts are failed then a video would be nice yes :) | |
| Oct 28, 2021 at 0:24 | comment | added | Nasser | @user110391 You need to first type ctrl with dollar, then this should open a new small window like I showed. Only then you type the Latex there. are you using version 12.3? If you like I can post a video showing how. But first you need to have that little new window open. You do NOT type ctrl with dollar inside the little window that opens up. Only pure latex goes there. | |
| Oct 28, 2021 at 0:21 | comment | added | user110391 | Not sure what typing the latex as plain text means. Does it mean like this: "\sum_{j=0}^{3} j". That is the last expression I tried to put in, when I tried putting the "ctrl$" in front of it. | |
| Oct 28, 2021 at 0:16 | comment | added | Nasser | @user110391 Could you post the latex on its own in your question that you are trying to input? as plain text? i.e. type the latex only. It could be your latex is not well formed. do not use double backslash. Only ONE backslash. You type normal latex in the input windows. I just tried it and it worked for me. | |
| Oct 28, 2021 at 0:15 | comment | added | user110391 | I tried doing this, but it didn't work. I have edited my question to include my faulty code. Not sure how I did it wrong. | |
