## Feminine vs. Masculine form for numbers

In addition to adjectives, Hebrew numbers are also gendered. Generally, you use the feminine form for counting feminine nouns, and the masculine form for counting masculine nouns. However, when you aren't counting anything in particular, default to the feminine form, as well as when in colloquial conversation.

## Numbers 1-10

Feminine form 0-10 :
| # | Hebrew | Transliteration | IPA |
| 0 | אֶפֶס | efes | /(ʔ)aˈχat/ |
| 1 | אַחַת | achat | /(ʔ)aˈχat/ |
| 2 | שְׁתַּיִם ~ שתיים | shtayim | /ˈʃtajim/ |
| 3 | שָׁלוֹשׁ ~ שלש | shalosh | /ʃaˈloʃ/ |
| 4 | אַרְבַּע | arba | /(ʔ)aʁ̞ˈba/ |
| 5 | חָמֵשׁ | ḥamesh | /χaˈmeʃ/ |
| 6 | שֵׁשׁ | shesh | /ʃeʃ/ |
| 7 | שֶׁבַע | sheva | /ˈʃe.va/ |
| 8 | שְׁמוֹנָה | sh'mone | /ʃmoˈna/ |
| 9 | תֵּשַׁע | tesha | /ˈte.ʃa/ |
| 10 | עֶשֶׂר | eser | /ˈ(ʔ)e.seʁ̞/ |
Masculine form 0-10 :
| # | Hebrew | Transliteration | IPA |
| 0 | אֶפֶס | efes | /(ʔ)ef.es/ |
| 1 | אֶחָד | eḥad | /(ʔ)eˈχad/ |
| 2 | שְׁנַיִם ~ שניים | shna'im | /ˈʃnajim/ |
| 3 | שְׁלוֹשָׁה ~ שלשה | shlosha | /ʃloˈʃa/ |
| 4 | אַרְבָּעָה | arba'a | /(ʔ)aʁ̞.baˈ(ʔ)a/ |
| 5 | חֲמִישָּׁה | ḥamisha | /χa.miˈʃa/ |
| 6 | שִׁישָּׁה | shisha | /ʃiˈʃa/ |
| 7 | שִׁבְעָה | shiv'a | /ʃivˈ(ʔ)a/ |
| 8 | שְׁמוֹנָה | shmona | /ʃmoˈna/ |
| 9 | תִּשְׁעָה | tish'a | /tiʃˈ(ʔ)a/ |
| 10 | עֲשָׂרָה | asara | /(ʔ)a.saˈʁ̞a/ |
Generally, masculine numbers just add an ה- to the end of the word.

# AI Art Generation Handbook/FLUX

FLUX 1.0 is a series of AI image generation models from Black Forest Labs (which is coincidentally formed by former Stable Diffusion engineers). Released in August 2024, it can understand natural language, contrasted to only keyword tags in Stable Diffusion, and offers higher quality and accuracy than Stable Diffusion. Three models are available: Schnell, Dev, and Pro. While Pro is proprietary and can only be used via API, Schnell is open-source and Dev is source-available, and both can be run locally.
Like Stable Diffusion, FLUX 1.0 can be fine-tuned for accuracy towards specific concepts.
In August 2024, FLUX 1.0 is fully supported by ComfyUI.
In September 2024, lllyasviel's Forge with the community support have integrated support for FLUX 1.0 into Forge WebUI
In October 2024, FLUX 1.1 Pro was released. Additional modes Ultra (with higher resolution) and Raw (tailored for photorealistic output) were released in November 2024.
In November 2024, Black Forest Labs announced the release of FLUX.1 Tools, a suite of editing tools.

# Open Sicilian with 2...Nc6

Here Black has decided to play Nc6 instead of d6 or other moves. If Black plays pawn to d5 later on then they have saved a tempo by not playing d6 first.

# Chess Opening Theory/1. e4/1...c5/2. Nf3/2...Nc6/3. a3

The delayed Mengarini Variation (French Wing Variation) is a variation of the Sicilian Defense where White plays a move that delays development for an interesting idea: playing the move b4. The move a3 itself is not the best choice since it does not control the center and does not develop any pieces.
Black can respond in several ways, including 3...g6 to fianchetto the dark-squared bishop, 3...Nf6, 3...d6, and 3...e5.

### Properties of Equality

| Property Name | Addition | Subtraction | Multiplication | Division |
| Commutative | $a+b=b+a$ | Doesn't work: $a-b\neq b-a$ This does: $a+(-b)=(-b)+a$ | $a*b=b*a$ | Doesn't work: $a/b\neq b/a$ This does: $a*1/b=1/b*a$ |
| Associative | $(a+b)+c=a+(b+c)$ | Doesn't work: $(a-b)-c\neq a-(b-c)$ This does: $(a-b)-c=a-(b+c)=a+(-b-c)$ | $(a*b)*c=a*(b*c)$ | Doesn't work: $(a/b)/c\neq a/(b/c)$ This does: $(a/b)/c=a*1/b*1/c=a/b*c$ |
| Identity | $a+0=a$ | $a-0=a$ | $a*1=a$ | $a/1=a$ |
| Inverse | $a+-a=0$ | $a-a=0$ | $a*(1/a)=1$ as long as a ≠ 0. | $a/a=1$ as long as a ≠ 0. |
| Distributive | $a*(b+c)=a*b+a*c$ | $a*(b-c)=a*b-a*c$ | $a*(b+c)=a*b+a*c$ | $(a+b)/c=a/c+b/c$ But wait: $a/(b+c)\neq a/b+a/c$ |
# Algebra/Chapter 2/Arithmetic

2.9: Algebraic Manipulation

## Parentheses

Let's look at when it is OK to add or remove parentheses. The purpose of parentheses is to establish precedence. Precedence tells you which operation goes first. The operation rules for precedence say to evaluate the parentheses first (PEMDAS!). But, what can you do with ${\frac {x+1}{2}}={\frac {1}{2}}$ ? $x+1$ doesn't have just one value; it has as many values as we choose to assign to $x$. This is where the distributive property shows its power. It allows us to rearrange the operations while maintaining precedence.
${\frac {x+1}{2}}={\frac {1}{2}}*(x+1)={\frac {1}{2}}x+{\frac {1}{2}}$
So we can change our equation to
${\frac {1}{2}}x+{\frac {1}{2}}={\frac {1}{2}}$
Add ${\frac {-1}{2}}$ to both sides
${\frac {1}{2}}x+{\frac {1}{2}}-{\frac {1}{2}}={\frac {1}{2}}-{\frac {1}{2}}$
${\frac {1}{2}}x=0$
And multiply both sides by the inverse of ${\frac {1}{2}}$
${\frac {1}{2}}x*2=0*2$
$x=0$
Parentheses allow us to ensure that we treat expressions that have variables as if they were a value. For instance, if we want to know for which values the expression ${\frac {2}{x+1}}=3$ is true we need to use the properties of real numbers to place the variable $x$ by itself on one side of the equals sign. To do this we need to get $x+1$ out of the denominator of the fraction. We can do this by multiplying both sides of the equation by $(x+1)$. We don't know what the value of $(x+1)$ is, but it will always be the same thing on both sides of the equation so it doesn't change the notion of equality.
$(x+1)*{\frac {2}{x+1}}=3*(x+1)$
We use the inverse property to re-write ${\frac {2}{x+1}}$ as multiplication.
$(x+1)*2*{\frac {1}{x+1}}=3*(x+1)$
And the associative property to re-write the multiplication.
$2*(x+1)*{\frac {1}{x+1}}=3*(x+1)$
And the identity property to re-write $(x+1)*{\frac {1}{x+1}}$
$2*(1)=3*(x+1)$
Since 2 * (1) has no variables we can evaluate it. We use the distributive property to re-write 3 * (x+ 1)
$2=3*x+3*1$
$2=3*x+3$
We subtract 3 from both sides of the equation.
$2-3=3*x+3-3$
$-1=3*x$
And multiply both sides by ${\frac {1}{3}}$.
$-1*{\frac {1}{3}}=3*x*{\frac {1}{3}}$
$-{\frac {1}{3}}=x$
Using parentheses and the properties of real numbers and equality we were able to get x alone to determine the only number for which our initial statement is true.
# Algebra/Chapter 2/Formulas

2.10: Formulas

## Formulas

A formula is a mathematical rule that is written in mathematical symbols.

## Word Problems

Word Problems are mathematical problems that are delivered in ordinary words, instead of mathematical symbols. Part of the problem with dealing with word problems that they first need to be translated into mathematical equations, and then the equations need to be solved.

### Working with Word Equations

Math is a kind of language, with its own "grammar"; to become "fluent" in math, you must understand its grammar. Some of the "grammatic" terms used in Math include:
| Addition (think positive!) | "in addition to" "plus" "added to" "more than" "and" |
| Subtraction (always negative) | "less than" "take away" "minus" |
| Multiplication | "times" "by" "each" |
| Division | "divided by" "per" "out of" |
| Equals | "is" "is equal to" "is equivalent" "their values are equal to each other" almost anything with the words "equal" or "same" |
This is not a definitive listing. While problems found in text books usually include these phrasings, you may encounter one where such words are implicit.

## Steps To Solving Word Problems

The majority of word problems in algebra can be rewritten as equations, which you can then solve. There are some steps to take as you analyze a word problem.
* Read Carefully
* Define A Variable (What You Are Looking For)
* Make A Plan
* Write An Equation
* Solve
* Is This Answer Reasonable?
These six steps may seem either obvious, but serve as the foundation to solving word problems.

# Chess Opening Theory/1. e4/1...e5/2. Nc3
## Vienna Game

White's wish is to advance the f-pawn two squares to remove Black's powerful e5 pawn and strike at the heart of their position. Now it is possible to play f4 on the second move, for the King's Gambit, but when no Black piece has yet declared its intentions is there not a degree of hit-and-hope about such a move? If you have the patience to let Black build their bridge before you blow it up: welcome to the Vienna Game, a poison-tipped opening from the nineteenth century.
If you should find yourself up against the Vienna as Black, keep your nerve. The harder White tries to checkmate you, the less time they have to develop naturally and control territory; consequently, if you survive the opening your hand is a little freer than in the Ruy Lopez.
Black for the moment has no threat to respond to, save the threat of f4 which cannot be reasonably prevented. When in doubt, develop a knight:
    2...Nf6: Falkbeer (or Berlin) Defence
The most common reply as it prepares to counter f4 with d5, adding to the equation another variable for White to keep track of.
    2...Nc6: Max Lange Defence
This allows Black to capture the pawn when it gets to f4, without having their active knight subsequently kicked by the e-pawn.
Other plausible moves are 2...Bb4 and 2...Bc5 both of which attempt to initiate a counter-attack.

# Chess Opening Theory/1. e4/1...e5/2. Qh5
## Wayward Queen Attack/Parham Attack
### 1. e4 e5 2. Qh5

The Wayward Queen Attack or Kentucky Opening is a very aggressive move. It violates an opening principle by bringing the queen out early. However, Black has to be careful, as White’s queen is placed on an aggressive square. The main purpose of 2. Qh5 is actually the resulting pressure on f7 after White plays 3. Bc4; the f7-pawn is guarded only by Black's king and is considered Black’s weakest pawn at the beginning of the game.
The safest option for Black is to play 2…Nc6, which guards the e-pawn and prepares 3…g6.
Black can also try playing 2…Nf6!?, the Kiddie Countergambit. Black sacrifices the e-pawn for a lead in development and many tempi against White’s queen.
2…g6??, attacking the queen immediately, is not recommended: it simultaneously leaves the e-pawn undefended and opens up the h8-rook, and White can win that rook by playing 3. Qxe5+!, forking the king and rook.
Note that this opening allows White’s quickest possible mate if Black plays 2...Ke7?? (3. Qxe5#).

## Parham Attack
### 4. Qf3

White renews the threat of (delayed) Scholar's mate 5.Qxf7# if Black does not prevent this, for example, if 4...Nd4?? to attack the queen, or 4...Bg7?? or 4...d6??. Black’s options are to play 4...Nf6, which successfully blocks the checkmate threat.

## Parham Attack
### 4...Nf6

Black blocks the attack from the queen. Although the black knight is "pinned" to the pawn (If it were to move, white would play Qxf7#), Black has been handed the moves ...Bg7 and ...O-O on a platter. Another idea is if White doesn't defend d4, instead playing 5. Nc3?, (which is also a common response between low rating players) Black has 5...Nd4! 6. Qd1 Bg7.

## Parham Attack
### 5. Nc3

Moving the knight to c3 seems natural, since it develops the knight and prevents Black's d-pawn advance. However, this move can be considered a mistake. This is because Black can gain a tempo by playing Nd4!, moving to an outpost which threatens to win the queen while also threatening to fork white’s pieces at the same time.
