What Is Mean In Math? Examples & Questions For Primary School
October 17, 2025 - A mean in math is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers. For example, with the data set: 8, 9, 5, 6, 7, the mean is 7, as 8 + 9 + 5 + 6 + 7 = 35, 35/5 = 7.

Definitions
There are some very basic words with two common inequivalent definitions, and math texts don't always tell you which definition they are using. Examples: The natural numbers may or may not contain zero, and both these definitions occur commonly. A ring may or may not be required to have a multiplicative identity. There are many, many words and phrases that have one definition that most texts use, but for which some texts give other definitions. For example, "positive" means "greater than zero" in almost all texts, except for certain European educational systems (perhaps only France), where it means "greater than or equal to $0$".

r/learnmath on Reddit: What does it mean to "define" something in math?
June 15, 2022 -
Hi everybody! I'm currently working through Linear Transformations and Matrices by F. A. Ficken and while I generally understand what's happening in each subsection, I keep getting stuck on the questions because I don't know what they're asking me to do. The biggest issue is that I don't know what it means when a question asks me to "define" something. I feel like I'm missing something major because I understood the section on recursive definitions and was able to "define" sequences based on that understanding but then questions started asking me to define a given equation such as a₀ = b and I have no idea what it wants me to do. Another question said to define the symbols that denote '1 choose 0' = 1 and '1 choose 1' = 1, I'm also completely lost there.
I feel like my issue is that I'm not in a math class with a prof who can explain these things to me but I really want to learn on my own. I tried looking for video lectures but I can't figure out what to search to get what I'm looking for.
Thanks so much in advance for any help anyone can provide.
Edit: here's a question I'm stuck on, https://imgur.com/a/2xs6HME

It's unlikely that the parts of the questions that say: "Define as" or "Define to be" are asking you to do anything. I know it sounds like they're telling you to do something, but what those phrases really mean is that they have created a name for something and are telling you what that name means. For example, if I said "Define the function f(x) to equal 1 when x > 0 and 0 when x <=0", then there's nothing for you to do. I'm basically telling you how to interpret expressions such as f(3). When you see f(3), I've just told you that f(x) = 1 when x > 0, therefore f(3) = 1. If I said define a sequence a(n) so that a(0) = 1 and a(n+1)=a(n)+3, I've just told you how to interpret things like a(1), a(2), a(3). So I'm not telling you to actually do anything, I'm just giving you information so that you can understand the next things that I write. We don't really do this in English because we don't really need to be constantly coming up with new names and symbols for things. But if I said to you that from now on when I say the word "ploof", I mean a "fluffy dog", then that would be the same as the mathematic directive: "Define 'ploof' to mean 'fluffy dog'". Note: I'm just guessing here. I could very well be that a question is asking you to come up with your own definitions. I'd have to see the entire question and surrouding context to be sure.

Just post the full question, it's easier to answer. Sometimes define just mean the same thing as solve, they want you to solve explicitly for something. Sometimes it is a conceptual question about making some intuition rigorous. Sometimes it means an explicit construction of something, but there are more than one constructions so it's a bit weird to say you "solve" for it.

June 24, 2024 - In the real world, when there is huge data available, we use statistics to deal with it. Suppose, in a data table, the price values of 10 clothing materials are mentioned. If we have to find the mean of the prices, then add the prices of each clothing material and divide the total sum by 10. It will result in an average value. Another example is that if we have to find the average age of students of a class, we have to add the age of individual students present in the class and then divide the sum by the total number of students present in the class.
