Are you looking for a way to type Ɛ (Backward 3 or Reverse 3) on your device? Well, you have landed at the right place. Here, I’ll show you how you can type Ɛ which is also generally referred to as the Backwards 3, Reverse 3, inverted 3, or flipped 3 in common language.
As there is no such symbol on any of the smart or physical keyboards of the devices it becomes completely impossible to type Ɛ. But you don’t have to worry about that, as in this guide I’ll show you how you can type the symbol Ɛ very easily on any of your Android, iOS, Mac, and Windows devices.
How to type backward 3 or Ɛ on PC and Phones
As I told you, there is no direct symbol anywhere on either of the physical or digital keyboards that can be used to type the backward 3. But this doesn’t mean that you can’t type it. There are a number of ways by which you can use the reverse 3 on any of your devices and they are mentioned below.
Method 1: Simply copy and paste Backward 3
The very first thing that you can do is just simply copy and paste the Ɛ symbol on your device. This is one of the most convenient and straightforward solutions to type backward 3 on any device.
If you are looking forward to this method, then you can simply copy the symbol from below.
Method 2: Use the Alt code to manually type Ɛ
If your work requires the use of the backwards 3 symbols again and again then, copying and pasting it, repetitively is not gonna be a solid solution.
In such a case you should rely on the Alt code of the Ɛ symbol so that you can type it conveniently on your own every time you need it. To type backward 3 using the Alt code:
1. Type 0190 where you want to insert the Ɛ symbol.
2. Now, press Alt + X key combination on your keyboard to convert the numerical code into Ɛ symbol.
Method 3: Use symbols if you are working on MS Word
Another way that you can use to type backwards 3 or reverse 3 is by using the symbols feature in the MS Word document. This is more convenient for those who want to insert the Ɛ symbol in their MS Word document.
1. Click on Instert tab from the top left of the MS Word window.
2. Now, select the Symbols option. This will bring you a small window of all the special characters and symbols.
3. From this list, look for the epsilon symbol i.e. Ɛ, and click on it to insert it into the MS Word document.
Method 4: Use Special characters in Google Docs
Besides MS Word you can also use the free online tools from Google i.e. Google Docs to insert the Ɛ symbol in the document.
1. Open Google docs on your web browser.
2. Click on Insert on the top left of the webpage.
3. Select the Special characters option from the list.
4. Select the Ɛ symbol from the list of symbols.
How to type backwards 3 on Android
Devices like Android smartphones and tablets do not come with any kind of option to type special characters that are not mentioned on the keyboard and hence typing the backwards 3 on Android is not possible manually by using any kind of ALT code or something like that. Hence in order to type backwards 3 on Android, you’ll have to rely on the copy-paste backwards 3 method.
How to type backwards 3 on iPhone
Just like Android, Apple also doesn’t provide any option to type any special character other than that mentioned in the virtual keyboard and hence you will have to rely on copy-pasting the backwards 3 symbols in this case as well.
Tip: Copying and pasting the Ɛ symbol is by far the most convenient way to type the backwards 3 symbols on any device. But for Android and iPhones, you can also use the Google Docs option as well as it is a web-based application that can be accessed on all kinds of devices capable of surfing the web.
What is backwards 3 symbol?
You may have seen the Ɛ symbol most probably in text messages, Instagram/Snapchat stories, WhatsApps Statuses etc. as it is used there very extensively to typically represent the heart or love symbol. It looks something like this:
But, if you dig a little deeper, then the Ɛ symbol has nothing to relate with the social media and it is actually a Greek letter that is called epsilon. It is the 5th letter of the Greek alphabet just like the letter E is the 5th letter of the English alphabet.
What does the backwards 3 or epsilon (Ɛ) mean in math and Physics?
Although the Greek language is not used very extensively across the globe and hence its alphabets are also not of high importance.
But when we shift from literature to mathematics and Physics, the influence of the Greek alphabet can be seen as there are many mathematicians and Physicians who belong to Greek origin and they introduce a number of Greek alphabets in these subjects.
And the Epsilon or the symbol Ɛ is one such greek alphabet. It is heavily used in the Mathematical study of Set Theory as a variable epsilon symbol ∈.
However, the normal Epsilon i.e. Ɛ is commonly used as a variable in equations. It is also commonly used as an “error term” in statistics/regression where Ɛ denotes an arbitrarily small, positive number.
