Consider the following:

Math teacher: "How can we turn 42 into 420 through multiplication?"

Student: "You times it by ten!"

Is this usage of times correct? I hear it so often that I suspect it may be correct. I'm sure the reason for this (potential) mistake is that it is correct to say:

"Ten times four is forty."

Does anyone know if this is correct or not?

    Apparently "you pays your money and takes your choice". Some people will think you're stupid, childish, or ill-educated if you say/write times. Others won't, but they won't think you're pedantic or stuffy if you write multiplied by, so you might think that's safest. – FumbleFingers Oct 18 '11 at 23:26

    I personally do not support the above usage of "times". I was just curious enough to find out if it was right or not. –  Oct 18 '11 at 23:27
  • Ah. So you already know which horse you're backing! I'll remember not to use times as a verb when writing to you then! :) – FumbleFingers Oct 18 '11 at 23:29

    @FumbleFingers Indeed! I would never use times in that context. It sounds awful when spoken and looks the same when written. –  Oct 18 '11 at 23:30
  • It's possible SE England is more tolerant of the usage than Canadians. Or, of course, maybe I'm stupid, childish, and ill-educated! :) – FumbleFingers Oct 18 '11 at 23:32
  • I don't know if all Canadians feel this way, I can only speak for myself. It is possible, though. –  Oct 18 '11 at 23:34

    The example sentence, “You times it by ten” doesn’t sound overly grating to me, though it’s not something I would ever use naturally myself. Changing it to the third person, however, makes all kinds of jarring, Gollum-like ear-graters fly through the air: “And how does he arrive at 420? He timeses 42 by ten”. If anything, I would find it less grating and more natural to say, “You time it by ten”. – Janus Bahs Jacquet Aug 15 '13 at 15:48
  • Rachel Riley, the maths wiz on English TV show "8 Out Of 10 Cats Does Countdown", very often uses "times-ed by", as do contestants. It sounds ugly and, frankly, stupid. Correct are "times" or "multiplied by" (or simply "by"). – Ralph Schneider Nov 08 '19 at 10:53

In Standard English, this usage of the word times is considered an error. It is often used by children and students when speaking of multiplication, for exactly the reason that you indicate: the formula X times Y equals Z has spawned the creation of a verb to times meaning to multiply.

However, using this in any kind of formal context is considered an error, and I have only ever encountered this usage from children. I would avoid it in writing altogether, and discourage students from using it.

    I think it's just one of those things you wouldn't say in a formal setting. Informally, it's said all the time, even by adults. – Sarhanis Oct 18 '11 at 23:19

    Merriam-Webster get quite worked up about this "error". I don't see anything wrong with it in informal speech, though if I was writing I think I'd always use multiplied by (or more likely just "x"). But NGram has thousands of written instances of times it by, and most of them aren't MW's vitriol. – FumbleFingers Oct 18 '11 at 23:20

    My kids' classmates use "verse" to mean "oppose," because of the word "versus." Will you verse me in basketball? – Chaim May 09 '19 at 16:54

When I was a child in primary school, anyone using "times" as a verb would be corrected by the teacher. The modern fashion is not to correct children's mistakes as it stresses them, or lowers their self esteem. So what once were considered errors become common usage, and rabble-pandering "authorities" like OED eventuallt accept this misuse of language as correct. You multiply two numbers together: you do not "times" them

Most dictionaries will tell you times is a preposition, though it is closer to an interposition, which some might call a conjunction. It could be seen as a noun with "ten times four" meaning "four, ten times", or by parsing "Learn your three times table." Alternatively, twice is seen as an adverb.

Personally I would accept times as a verb if that is how somebody wanted to use it, for example if they said "Times the decimal fraction by 100 to get a percentage", though I would more often use multiply in that context.

  • I accept language as a dynamic and evolving thing. I query the acceptance of the repurposing of words on the basis that teachers are unable to explain them properly. (NB No disrespect to teachers: I distinguish between "unable" and "incapable".) – KDM May 19 '23 at 22:19

Times comes from the idea of repetition!

Q. The pirate put five coins into the bag. If he did this ten times then how many coins would the bag contain?

A. The bag contains ten times five coins (fifty)

Mathematically, times belongs between two numbers (and belongs to the first one if you see what I mean)

Hearing "You times that number by that other number" makes me want to vomit!

Junior math(s) teachers will often say "times means multiply", but the two are not always interchangeable.

The answer is YES! It is correct. Why say mul-ti-ply when you can say times? Why say mul-ti-pli-ca-tion when you can say timesing?

As a verb instead of multiplying:

1994, Harvey Mellar, Learning with artificial worlds: computer-based modelling in the curriculum:
I've taken the calories and the amount of food . . . and it's 410 calories per portion timesed by 6 portions which [sic] the answer was 2460 calories...

1995, Mathematical Association, The Australian mathematics teacher, Volumes 51-53:
A student as junior as Year 4 informed me that he made a forward estimate of cheeses in 100 trials by 'timesing both numbers by 10'...

1998, Psychology of mathematics education, Volume 2:
Alex: Yeah - if you're timesing that distance there by this height, it will disappear.

As noun instead of multiplication:

2011, Willis, et al, Willis's Elements of Quantity Surveying, 11th ed, p33, Wiley-Blackwell, West Sussex, UK:
Calculation should be made as waste on the dimension paper and not mentally, and timesing should be done consistently.
When timesing becomes complicated, it will help considerably in tracing items if the method of timesing is consistent.

There are many byspels ... Resist it if you like, but you're spitting into the wind.

Late edit: I only now realized that I forgot to mention that times as a verb (times, timesed, timesing) is in the OED.

    'correct' usually means in reality 'accepted by the standard'. Using 'times' as a verb might be used informally all over the place, but is definitely not standard and using it as a student in an assignment or in any communication with anything other than the most informal situations is a grave stylistic solecism. – Mitch Dec 28 '11 at 02:55
  • @Mitch Byspel means example (http://en.wiktionary.org/wiki/byspel). Mitch and Mahnax ... As you can see in the byspels (examples) I posted, it is already being used in formal writing and published works. "Ergo" it is now standard and proper. Only the Latinate loving pedants are bemoaning and having fits. The rest of us have moved on. – AnWulf Dec 29 '11 at 02:54

    @AnWulf: 'byspel' is not a recognized word in modern English. – Mitch Dec 29 '11 at 03:10

    @AnWulf: Your first three examples are all quotes of informal speech by students. For ESL students, if you use 'timesing' you will sound foreign or uneducated. – Mitch Dec 29 '11 at 03:13
  • @Mitch Maybe you should inform the Logan School system to stop teaching the word: SIGN OF THE *TIMESINGS* AND DIVIDINGS — worksheet .doc format

    Does this sound uneducated? "… you will naturally be concerned with the propriety of the additional *timesing* allowance for taking into account the vertical positioning of the upper floors." — Ronald M. Skitmore and Vernon Marston, Cost Modelling, Taylor & Francis, p. 178, 1999

    @AnWulf If you did not insist on its "correctness", you might not be downvoted. OED is only recording the usage, as its lexicographers are more descriptivistic now. Still, people say whether a certain usage is correct or not. When most people say it is incorrect, it is, then. This can certainly change, and the once controversial usage of words like "hopefully" can be mainstream. This does not happen all the time, though. At least for now, I consider "times" ugly as a verb, and won't accept it. – Yongwei Wu May 27 '15 at 04:19
  • I'm surprised you didn't add 'The times they are a-changin' '. – Edwin Ashworth Nov 08 '19 at 14:37
  • It's absolutely incorrect to use a preposition as a verb and even worse that the only reason is "laziness." It's thinking like this which allows "text" to be past present and future for the sending of an SMS. – KDM May 19 '23 at 22:24

Sorry english is not my language but it seems that saying or writing "multiplied by" should be the correct as it is from mathematics or scientific, by the other hand saying "times" it sounds time, clock, watch...................come on guys..............save the correct way to use the language. It is my humble opinion with all respect.
