-## Binary
-
-Binary is a base-2 numeral system: A simple way to represent numbers using only two states.
-

-### Speaking Binary
-
-> The information in this section is non-standard, and mostly a curiosity.
-
-You may struggle to pronounce large binary numbers, as saying a long list of 0s and 1s is very inefficient. Instead, we can do something like this:
-
-![speaking binary](sb1.png)
-
-To be able to say any binary number, list the number, starting by the last digit:
-
-![speaking binary](sb2.png)
-
-And pronounce the ones that correspond to a `1` bit.
-
-![speaking binary](sb3.png)
-
-#### Pronounce a Binary Number at a Glance
-
-1. Break the number at its largest pair of bits.
-    
-    ![speaking binary](sb4.png)
-    
-2. Represent the left and right sides.
-    
-    ![speaking binary](sb5.png)
-    
-    In this example, there is a `two` in the order of magnitude `hex`.
-    
-3. Continue to represent the left and right sides recursively.
-    
-    ![speaking binary](sb6.png)
-    
-    The last number is `four`.
-
-#### Decode a Spoken Binary Number
-
-Starting with `two hex four`:
-
-1. Find the largest power of two.
-    
-    ![speaking binary](sb7.png)
-    
-2. The number is equal to the left side, times the order of magnitude, plus the right side.
-    
-    ![speaking binary](sb8.png)
-
-#### Avoiding Repetition
-
-Repetition can be avoided by combining some very common, small numbers:
-
-![speaking binary](sb9.png)
-
-![speaking binary](sb10.png)
-
-These shortcuts essentially create a quaternary system to pronounce binary, but in this case, the result improves spoken efficiency by a lot.
-
-## Arithmetic Operations
-
-### Addition
-
-Adding two numbers can be done using a simple, manual algorithm: By adding the last bit of both numbers first, carry if necessary, then move on to the next number, and so on.
-
-| **+** | 0 | 1  |
-| ------- | --- | ---- |
-| 0     | 0 | 1  |
-| 1     | 1 | 10 |
-
-![addition](addition.png)
-
-> To add numbers more efficiently by hand, you can group bits together and memorize the patters, effectively doubling your speed.
-> 
-> ![hand addition](hand_addition1.png)
-> 
-> To improve calculation speed even further, you can group more bits, and learn those patterns as well.

-
-#### Half Adder
-
-Add 2, single-digit binary numbers.
-
-| **A** | **B** | **Carry** | **Sum** |
-| ----- | ----- | --------- | ------- |
-| 0     | 0     | 0         | 0       |
-| 0     | 1     | 0         | 1       |
-| 1     | 0     | 0         | 1       |
-| 1     | 1     | 1         | 0       |
-
-![image68](image68.png)
-
-#### Full Adder
-
-When adding 2 binary numbers, one operation might return a carry value, which the `half adder` can't accept, as it only has 2 inputs.
-
-![image69](image69.png)
-
-To solve this issue, a `full adder` accepts 3 inputs.
-
-![image70](image70.png)
-
-#### 8-Bit Adder
-
-![image71](image71.png)
-
-### Subtraction
-
-Subtraction can result in negative numbers. Like how additions need a carry, subtraction needs a borrow.
-
-#### Half Subtractor
-
-Subtract 2, single-digit binary numbers.
-
-| **A** | **B** | Diff | **Borrow** |
-| ----- | ----- | ---- | ---------- |
-| 0     | 0     | 0    | 0          |
-| 0     | 1     | 1    | 1          |
-| 1     | 0     | 1    | 0          |
-| 1     | 1     | 0    | 0          |
-
-![image72](image72.png)
-
-#### Full Subtractor
-
-A `full subtractor` accepts the borrow value, allowing us to chain results.
-
-| **A** | **B** | **B**in | **Diff** | **B**out |
-| ----- | ----- | ------- | -------- | -------- |
-| 0     | 0     | 0       | 0        | 0        |
-| 0     | 0     | 1       | 1        | 1        |
-| 0     | 1     | 0       | 1        | 1        |
-| 0     | 1     | 1       | 0        | 1        |
-| 1     | 0     | 0       | 1        | 0        |
-| 1     | 0     | 1       | 0        | 0        |
-| 1     | 1     | 0       | 0        | 0        |
-| 1     | 1     | 1       | 1        | 1        |

-#### 8-Bit Subtractor
-
-![image74](image74.png)
-
-### Multiplication
-
-Multiplication is also similar to its decimal counterpart, but because binary is so small compared to decimal, the steps are also much simpler.
-
-First, multiply the top number to every digit of the bottom one, and then add the results together.
-
-| X   | 0   | 1   |
-| --- | --- | --- |
-| 0   | 0   | 0   |
-| 1   | 0   | 1   |
-

-
-#### 2-Bit By 2-Bit Multiplier
-
-![image75](image75.png)
-
-### Division
-
-1. Find the smallest part of the dividend greater than or equal to the **divisor**.![d1](d1.png)
-
-  
-2. Write the first digit of **the answer**, and **copy the original divisor down**.![d2](d2.png)
-
-  
-3. Subtract the **aligned dividend digits** by **the digits under the dividend**.![d3](d3.png)
-
-4. Lower **the next dividend digit**.![d4](d4.png)
-
-5. Is **the total** greater or equal to the **divisor**? If so, add a `1` to the answer. If not, **add a `0` to the answer and return to step 4**.![d5](d5.png)
-
-
-6. Return to step 2, until you reach the end of the number. If you reached the end, you found **the answer**.![d6](d6.png)
-
-### ASCII
-
-Binary can also be used to represent characters.
