I always use c). I write using cursive-ish letters for handwriting, so that's naturally what I use for math (well, physics in my case). Plus, I feel like it helps disambiguate with capital letters (which I typically write with a typewriter-like style in equation, but sometimes cursive-style too). I also sometimes artificially introduce differences to disambiguate : i make sure that my capital X is more tall than wide, i write real multiplication with a very small × sign, and cross product for vectors with a much larger × (the height of a capital letter, but I make sure the branches are at a good 90° to differenciate with a capital X). Using cursive-style also helps diferentiate v, from V, from lowercase nu

[@elatior]

I write it as in A) as it's the most efficient. I haven't seen anyone write multiplication as "x" beyond the context of simple arithmetic. For the cross product symbol, the vectors get their own arrows and x is rarely used as the vector name so it isn't confusing. You can also write the operator symbol slightly higher than the variables.

[@NaThingSerious]

I’ve always been taught and used the curved x for maths (the channel logo as you called it), it’s just as quick as the regular x as it’s till only 2 lines, and I find it’s even easier to write as once you finish your pen is already on the correct side (as in the pen finishes on the right, whereas when writing x normally, the pen ends on the left). When I’m writing quickly, sometimes it can end up looking more like D, the æ looking one, but I never do it with straight lines as I still use the multiplication symbol as an x quite a lot.

[@Inspirator_AG112]

Lower-case X I just always do normally, English or math. Upper-case X, however, I always do normally *except it is crossed, like some people do Zs or 7s;* this is to differentiate it more from a lower-case X. (Also English or math.)

[@aComedicPianist]

I write x like X) by not lifting up my pencil. It’s way harder to show it with text. Writing a straight vertical line is the most ambiguous thing in my handwriting: it’s both a lowercase l and the number 1 (I use the cursive l in math). It looks like a 2 from everyone I’ve heard and is read as such by them if they aren’t told that it’s a 1. The weirdest part is that my 2’s get read as 2’s but look so much different from my 1’s. My 1 looks like a crowbar but with goosenecks on both ends, starting concave down and ending concave up, but the “shaft” is still vertical (enough). I like to think of the goosenecks as serifs. 😊 Writing something like |ln1| would probably be super confusing, but I always put parentheses for functions, so I would write it as |ln(1)|. I do write absolute value bars as completely vertical and longer than any of my straight lines, no goosenecks or serifs. My 11 could also be read as an uppercase U, but I write an uppercase U without serifs. My 11 is also how I start my uppercase H.

[@someonestolemyname]

Most people I see use A), but I was taught to use C) since primary school and that is what I stick to ever since. B) is like a cursive x and I can understand why people would use it if they are used to write cursive, but I tend to mode change to print when I write maths lest I write function names in cursive. In regards to Greek Chi, I usually write it with a very long down stroke and a small upstroke so it looks more like a flipped and rotated cursive f.

[@nickcampbell3812]

This reminded of me about how I write my v's in math. I and v are quite similar letters to write, but their functions in English are very different on account of u being a vowel, which means it is rather difficult to mistake a u for a v or vice versa in a normal word. However, u and v are used together sometimes in math. For example, Integration by Parts usually uses u and v. Some problems with vectors will also use u and v. Some letters just tend to be used in pairs: a,b c,d f,g,(h) i,j h,k m,n p,q r,s,(t) u,v (w), x, y, (z) To name some groups I've seen.

At least in France but in other countries as well, writing the unknown variable as x or χ is seen as the sign of a beginner/outsider, because the cross shapes can easily be mistaken for the multiplication sign ×. The most common way by far is æ, with ɔc being the other, marginal but still present way to write it, although it's somewhat childish. In addition, the unknown variable (or any other variable) is never uppercase. This eliminates the confusion between 9 (which is full width and has a curved tail) and q, and 2 and z (but plenty use the cursive 𝔷)

[@best-girlviro819]

C takes the same amounf of time as AB, D happens when I write X very fast and it just becomes continuous. I have done all variations and have settled on C being the least ambiguous. Also if you do physics another big thing is v and u look the same. My solution is to add a curl in v as done with B.

So for g I do something like "ꬶ" instead with the hook grossing itself. I go a bit lower like that unicode character, like a non-italic version of "ℊ". For l and 1, I write 1 not as a single stroke, but with the extra small diagonal line on its tip, and l is slightly curved, a bit like an opening parenthesis, with a more pronounced curve at the bottom. The best unicode representation I could find is "ᶩ", but I also curve it inwards. The extra loop I don't do. Also, 7 is "7̵" for me, with an extra horizontal line through the center to distinguish it better from 1. For Z I do "Ƶ", with a horizontal stroke rather than a perpendicular one to the other line.

I've always used a) as the operator and c) for a variable.

[@DjVortex-w]

No mathematician of any repute would succumb so low as to write a product with the × symbol.

[@throwawayavclubber7269]

What about u⃗ × v⃗?

[@Rio_1111]

​@@throwawayavclubber7269That one makes it distinguishable because it's only ever found beween vectors, wich always have the little arrow on top.

[@vqinet3287]

A has work arounds for most situations, but in linear algebra where the dot & cross products are different, you really want c or d for clarity

[@DionDPR]

I use A, but the right part is connected and not separated, lol. Well, i guess B is closer.

[@Yubin_Lee_Doramelin]

I write "normal x" as cursive (C), or (D) if I have to write really fast. I don't write x as (A) usually, because it requires different pen when x is a vector, which is normally written as bold characters. Well, (B) though... the letter "chi" has been written by me for chi-square distribution.

[@CasabaHowitzer]

You use bold characters in handwritten text? Why? Just put an arrow above the character to denote a vector.

[@Yubin_Lee_Doramelin]

@CasabaHowitzer Yes. I don't use arrows to denote a vector because not every vector is Euclidean, and the Vector Space is much broader than Euclidean Space. I think I repeated each stroke to bolden the letters...

[@emilwandel]

I write it with different stroke order. left down to rightup and then leftup to right down. I was taught to write left to write and to start at the line with lowercase letters. Backstrockes are rare. Anyway I find it hard to decipher channel logos. and x is a cross not a soft touch. Chi is a letter that goes below the writing line and is easy to distinguish. Crossproduct x is not poistioned at the ground line and blocked like a square. u, v, w, n, ny my, are very hard to decipher. More over one and pipe are the worst. it just looks like a prionsrr marking days.

[@lochie2804]

All I know is that lower-case "x" has to look different to "×" Additionally, lower-case letters are generally better to use than capital letters because capital letters can sometimes mean different things I tend to use option c because it's curvy, unlike × and X Edit: I just finished watching the video, kinda surprised my method isn't at least top 2, but I guess that's because we're all taught different things and/or tend to choose what's easiest for us. I'm fairly certain I've always seen x, throughout schooling, as the way I do it. Oh well.

[@mtaur4113]

Mine is usually closer to (a), but if there is a cross product × in the mix, it can be important to have that cross be the straightest and most symmetric cross ever, and it also hovers mid-line higher than x sitting on the ground, so it is fine. Also v and w tend to show up more than x here.

[@li-am-3]

i do c of course

[@md2perpe]

I write it as alternative A. I'm Swedish and here we usually use ⋅ for product, not ×, so there is no big risk of confusion.

[@EagleFPV43]

A for multiplication and C for a variable

[@Damons-Old-Soul]

א Is close to how I have always written it. It is the lowercase version of the cursive x, that I learned as a kid. _(Copy and paste gave me problems and that is why it is weirdly placed)_

[@RooiGevaar19]

I guess it's a RTL script problem. When I mix Hebrew and English, sometimes the apps can't set their script directions properly.

[@tambuwalmathsclass]

I used the last one always

[@aoay]

I use option A for upper case X and option C for lower case x. Since I am not trying to join my mathematical symbols together I don't use a cursive script.

[@tomahawk3645]

D. The teachers told me to in fourth grade math class for algebra. Doing it ever since. For every other case I write it normally

[@amazingfireboy1848]

My 8th grade math teacher forced our class to write χ because apparently everyone in college would look at us weird or something, and now in college I'm the weird one 💀

[@Phi1618033]

B is my way.

[@CherryBlossomBeats]

Funnily enough i dont write x like any of these, its a little hard to describe over text but the way i do it is top right corner -> bottom left corner -> top left corner -> bottom right corner, with the bottom left to top left part being connected so theres three lines instead of two like a normal x, I write in a sort of half cursive, its not proper cursive but i often connect strokes in letters and words just bc i write so fast

[@justkev1044]

Wouldn’t that be easily confused with “proportional to”?

[@xardasnecromancer590]

The last one looks more like Greek kappa. I personally use the third option and though it's the same with Cyrillic "cha" (pronounced like Greek chi, though when followed by i it's much softer in Greek), I don't recall using Cyrillic letters in maths.

[@hongkonger885]

I somehow ended up writing a blend between A and B. It's like B but the first stroke has the curve moved to the centre of the x.

[@joe_z]

I write x like a shortened χ (because it's cursive), but I write actual χ noticeably longer, so it's okay.

[@jasonenns5076]

The Greek letter: χ notice that the bottom is complete under the line like the letter: g.

[@kyleo.6946]

I use A but when working with probability functions the X is the random variable and the value is the curvy x like C

[@allnamesaretakenb4]

That lower case q was just wrong.... you write it like you first wrote the lower case q, but with a small horizontal line across the bottom part of the vertical line....

[@GroundThing]

I'd imagine, and I'm sure it differs by location, that the "x" (outside the cross product) way of symbolizing multiplication is going to disappear within a few generations, for a few reasons: a) the advent of greater and greater digital proliferation, which "*" as the standard, and b) it wasn't that long ago that algebra was considered "advanced math" (in my mom's school, Algebra was taken at the end of High School as an optional class, and if that seems bizzare to folks younger than me, remember not only did you not used to always have a calculator in your pocket, but calculators used to be expensive business machines, so mental and paper arithmetic used to be a lot more important), and while that has mostly changed, there was a lag as elementary school teachers may not have ever taken algebra or beyond, but that lag is going away, so now I suspect teachers are more inclined to the thought of "why should I teach this increasingly archaic symbol for multiplication, when I can just present the dot syntax?" They may need to learn it because, for instance, calculators still use it, but that's even likely to change if the culture changes.
