How do you type mixed numbers on your computer?
Lets say our number is 31/2. First, if we wanted to write out a
mixed number, for the non-fractional part just type the number like
you usually do. This is what you should get now: 3 Now press the
superscript button or the keyboard shortcut for it. It will most
likely look something like this: X2 or ab or something similar. Now
press the numerator of the fractional part of the mixed number. It
should look like this: 31 Now get out of superscript mode and type
a forward slash: 31/ Now press the superscript button or the
keyboard shortcut for it (X2 or ab) and type in the denominator of
the fractional part and you are done! 31/2
If you are not using this particular text window..
I use the Firefox add-on abcTajpu to print out fractions in text
windows.
For example ½ ⅓ ¾
A number of the fractions have Unicodes.
To find the unicode of a symbol you print it out in Microsoft
Word and then highlight it and press Alt+x
You can also superscript and subscript numbers like this..
¹²/₃₄
Again I use abcTajpu to do that.
What it looks like depends alot on the font that you are using.
Sometimes it doesn't look great.
Below I will cut and past a detailed set of instructions I
created for using the add-on.
You can take what you want from it. I will leave it complete in
case you can use the other stuff as well, such as printing Greek
letters and other mathematical symbols.
============
There is a great Firefox add-on that you can use to insert
mathematical symbols into your answers. For example, using the
add-on it only takes one extra key press to write the Kinetic
Energy formula in the form Ek=½mv² rather than in the less clear
form Ek=1/2mV^2. It only take two key presses to insert the
integral symbol, ∫ , i+Insert ⇒ ∫ You can insert each of the Greek
symbols with two key presses. a+Insert ⇒ α , l+Insert ⇒ λ ,ect You
can also easily insert commonly used phases and equations. The name
of the add-on is abcTajpu and it can be found at…
https://addons.mozilla.org/en-US/firefox/addon/459 Below are the
instructions to set it up quickly. After loading the add-on and
restarting Firefox, go to your add-ons (Ctrl+Shift+A) and click the
Options button in the abcTajpu add-on. • Then copy and paste the
following text in the Text window that pops up. Delete the sample
text that is already in it. XXXXXXXXXXXXXXXXXXX < Don't include

XXXXXXXXXXXXXXXXXXX < Don't include this. •Click the Insert
option at the bottom of the page. (Click F1 if using the insert key
does not suit you) •Uncheck the "Add Accent" keys in the middle of
the screen…Alt-F1,Alt-F5, ect…. I've created the above text for my
own use but it should suit the general user. Below is an
explanation of the syntax. The format used by the add-on is...
InputCharacterOrCharacters = OutputCharacterOrCharacters| It must
end with the vertical bar | The OutputCharacterOrCharacters may
also be the 4 digit Unicode number of a character in the form
%u1D3F (To find the Unicode number of a given symbol... In
Microsoft Word, type the character, highlight it and then press
Alt+x. You can also find the symbol if you are given the Unicode
number using the same method. http://en.wikipedia.org/wiki/Unicode)
Once the add-on is installed and set up, when you are in a text
field on any website you type the input character then press the
insert key and it is changed to the output character. Below is the
interpretion the first line of the text that I've created...
i=∫|s=√|√=√[]|I=∞|P=∂|S=Σ|O=Ω|F=Φ|h=ℎ|ℎ=ℏ|ℏ=ħ|ħ=h| i>∫ (Integral
symbol) s>√ (The first time you type 's' and then press the
insert key you get √) √>√[] (The second time you press the
insert key you get √ plus square brackets) I>∞ (Capital i is
changed to the infinity symbol) P>∂ (Capital P for "Partial" is
changed to the partial integration symbol) S>Σ (Capital S to
Capital Sigma) O>Ω (Ohms) F>Φ (Φ is the uppercase Greek Phi
symbol pronounced "Fy" h>ℎ>ℏ>ħ (Typing 'h' and pressing
the insert key repeatedly takes you through several versions of
Plank's constant) Second line of text...
a=α|b=β|g=γ|e=ε|t=θ|k=κ|l=λ|m=μ|n=ν|p=π|r=ρ|g=σ|f=φ|y=ψ|o=ω| These
are some of the common lower case Greek letters a=α| (Alpha) b=β|
(Beta) g=γ| (Gamma) e=ε| (Epsilon) t=θ| (Theta) k=κ| (Kappa) l=λ|
(Lambda) m=μ| (mu) n=ν| (nu) p=π| (Pi) r=ρ| (Rho) g=σ| (Sigma,
Lower case s was used) f=φ| (Lower case Phi symbol, pronounced fy)
y=ψ| (Lower case Psi symbol pronounced sy ('s' symbol was already
used)) o=ω| (Omega) Third line of text...
α=β|β=γ|γ=δ|δ=ε|ε=ζ|ζ=η|η=θ|θ=ι|ι=κ|κ=λ|λ=μ|μ=ν|ν=ξ|
ξ=ο|ο=π|π=ρ|ρ=σ|σ=τ|τ=υ|υ=φ|φ=χ|χ=ψ|ψ=ω|ω=α| This line of text lets
you get any of the lower Greek letters by first creating one of the
ones you know and then repeatedly pressing the insert key until you
get to the one you want. Next line of text...
D=Δ|Δ=∇|∇=Σ|Σ=Φ|Φ=Ψ|Ψ=Ω|Ω=Δ| The capital D symbol gives you the
capital Greek Delta symbol, pressing insert again gives you the del
symbol ∇ used for divergence, curl and the Laplacian. Note: You can
access all of the Greek letters and many other symbols by right
clicking in the text field and going to abcTajpu in the context
menu. Next line of text...
0=⁰|⁰=₀|₀=⁰|1=¹|¹=₁|₁=¹|2=²|²=₂|₂=²|3=³|³=₃|₃=³|4=⁴|⁴=₄|₄=⁴|
-=⁻|⁻=₋|₋=⁺|⁺=₊|₊=∓|∓=±|±=⁻|n=ⁿ| The part ⇒ 0=⁰|⁰=₀|₀=⁰| lets you
type 0 then press Insert to get a superscripted 0 then press insert
again to get a subscripted zero. It is the same for the numbers 1
through to 4 The part ⇒ -=⁻|⁻=₋|₋=⁺|⁺=₊|₊=∓|∓=±|±=⁻| gives you the
superscripted plus and negative symbols (⁻ ₋ ⁺ ₊ ) as well as the
plus and negative symbols together (∓±). Type the negative symbol -
and then the insert key repeatedly. Finally, ⇒ n=ⁿ| , the letter
'n' can be superscripted. Next line of text...
12/=½|13/=⅓|14/=¼|15/=⅕|16/=⅙|23/=⅔|34/=¾|25/=⅖|35/=⅗|45/=⅘| To get
a fraction, type the numerator and denominator and then the forward
slash, then the Insert key. Note: The slash comes after the
numerator and denominator. Next line of text...
A=↑|↑=↓|↓=→|→=←|←=↔|↔=⇒|⇒=⇔|⇔=↑| Type 'A' then the Insert key
repeatedly, to get a selection of arrows Next line of text...
%u003D=≈|≈=≠|≠=∝|∝=≡|≡=≥|≥=≤|≤=%u003D| Type the equal sign '=' then
the Insert key repeatedly to get the selection of equivalency
symbols. "003D" is the Unicode for the equal sign. Next line of
text... E=∈|∈=∅|∅=⊂|⊂=⊆|⊆=∪|∪=∩|∩=∈| Type 'E' then the Insert key
repeatedly to get the selection of symbols use in set notation.
Next line of text... C=©|©=•|•=-|-=ħ|ħ=•|•=×|×=©| Type 'C' then the
Insert key repeatedly to go through a selection of odds and ends.
The add-on can be used to quickly insert commonly used equations,
phases or even paragraphs. If you want to start a new paragraph in
your comment you have to use the Carriage Return Unicode 000D and
write "%u000D" I've included a few comments and equations that I
use. Note: I've chosen to end all InputCharacter sets that output a
sentence with the exclamation mark !. This turns out to be useful.
Ek!=Ek%u003D½mv²| (This is the Kinetic Energy formula, Ek=½mv², you
have to use the Unicode number for the equal sign)
dca!=d%u003Dd₀+v₀t+½at² (Distance with Constant Acceleration
formula) wwe!= Wikipedia.org, "The World's Encyclopedia"| fgfa!=For
the great Firefox add-on used to insert the mathematical symbols in
this answer, and detailed instructions, search "abcTajpu" in Yahoo
Answers or go this link. https:/XXXXXXXXXXXXXX| Concerning the X's
above, at the time I was posting this text I could not at the same
time know the name of this link so you would have to cut and paste
it. Note: The add-on's help instructions talk about needing to hold
down the Ctrl+Shift+Alt keys while pressing the insert key, that
not my experience. If you have any corrections, comments or
formulas you would like to share with me and others, add comments
to this "Question", I will be extending the time this Question is
Open so that I can modify it. I will be posting this "question"
several times more in the different Yahoo Answers sections to reach
more people (This, given the time it took me to create it). Email
me if you use the add-on and want to know of any over sights I've
made or of any good suggestions that come up.
