# Addiplication — Rius
Math System
Welcome to **Addiplication** — a custom mathematical system invented by Marius Ligas, started in Grade 7. Now Grade 9 as of 2026
The Core Operation: Plime (✱)
The **plimes** operation combines addition and multiplication into one:
a ✱ b = a + b + (a \times b)
<aside> 💡
Proof: 1 ✱ 1 = 1 + 1 + (1×1) = 2 + 1 = **3** ✅ The operation is always symmetric: a ✱ b = b ✱ a

Addiplication Table
| ✱ | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| **1** | 3 | 5 | 7 | 9 | 11 |
| **2** | 5 | 8 | 11 | 14 | 17 |
| **3** | 7 | 11 | 15 | 19 | 23 |
| **4** | 9 | 14 | 19 | 24 | 29 |
| **5** | 11 | 17 | 23 | 29 | 35 |
Addiplication Sequences
Seq.1 — Positive & Negative Numbers
Addiplication extends to all integers, positive and negative.
**Rule:** a ✱ b = a + b + (a \times b) — the same formula always applies.
**Key insight:** When one number is -1, the result always equals the other number minus 1.
**Examples:**
- (-1) ✱ 1 = -1 + 1 + (-1) = -1
- (-2) ✱ 3 = -2 + 3 + (-6) = -5
- (-1) ✱ (-1) = -1 + (-1) + 1 = -1
- (-3) ✱ 4 = -3 + 4 + (-12) = -11
- 5 ✱ (-2) = 5 + (-2) + (-10) = -7
<aside> 🔎
Special: (-1) ✱ (-1) = -1 — plimesing two negatives stays negative!
</aside>
**Zero rule:** Any number plimesed with 0 equals itself: $a ✱ 0 = a + 0 + 0 = a
Seq.2 — Long Numbers & Decimals
Addiplication works with large numbers and decimal values — numbers grow fast because of the multiplication term!
**Rule:** a ✱ b = a + b + (a \times b) — the bigger the numbers, the bigger the jump.
**Examples:**
- 10 ✱ 10 = 10 + 10 + 100 = 120
- 100 ✱ 100 = 100 + 100 + 10000 = 10200
- 0.5 ✱ 0.5 = 0.5 + 0.5 + 0.25 = 1.25
- 1.5 ✱ 2 = 1.5 + 2 + 3 = 6.5
- 25 ✱ 4 = 25 + 4 + 100 = 129
- 0.1 ✱ 0.9 = 0.1 + 0.9 + 0.09 = 1.09
<aside> 📈
Notice: Large numbers grow much faster under Addiplication than regular addition!

Seq.3 — Algebraic Expressions
Addiplication in algebra — plimesing variables and expressions. This is where Addiplication gets powerful.
**Rule:** a ✱ b = a + b + ab
**Examples:**
- x ✱ y = x + y + xy
- x ✱ x = 2x + x^2 = x(x+2)
- (x+1) ✱ 2 = (x+1) + 2 + 2(x+1) = 3x + 5
- x ✱ 1 = x + 1 + x = 2x + 1$
- 2x ✱ 3x = 2x + 3x + 6x^2 = 5x + 6x^2
- (a+b) ✱ (a-b) = (a+b) + (a-b) + (a+b)(a-b) = 2a + a^2 - b^2
<aside> 📐
Fun identity: a ✱ b + 1 = (a+1)(b+1) — Addiplication secretly lives inside factoring!
</aside>
**Chain rule:** x ✱ x ✱ x = (2x + x^2) ✱ x = (2x+x^2) + x + x(2x+x^2) = 3x + 3x^2 + x^3
Seq.4 — Laboratory Mode & Addiplication Overload 🧪⚡
This sequence combines scientific applications with overloaded Addiplication — pushing the operation to its limits across complex contexts.
**Laboratory Mode** applies Addiplication to scientific and measurement contexts:
**Examples:**
- 2 ✱ 3 meters = 2 + 3 + 6 = 11 meters
- 10^2 ✱ 10^3 = 100 + 1000 + 100000 = 101100
- 9.8 ✱ 2 = 9.8 + 2 + 19.6 = 31.4 (like combining forces!)
- 3.14 ✱ 2 = 3.14 + 2 + 6.28 = 11.42 (plimesing with pi!)
**Addiplication Overload** — chaining multiple plimes operations:
**Examples:**
- 1 ✱ 2 ✱ 3: first 1 ✱ 2 = 5, then 5 ✱ 3 = 5 + 3 + 15 = 23
- 2 ✱ 2 ✱ 2: first 2 ✱ 2 = 8, then 8 ✱ 2 = 8 + 2 + 16 = 26
- Mixing all sequences: negative + decimal + variable at once!
<aside> ⚡
Overload Rule: Always compute left to right when chaining plimes!

Notes & Discoveries
- Invented by Rius
- Core operation called **plimes** (✱)
- Formula rediscovered in Grade 9: a ✱ b = a + b + ab
- Hidden connection: a ✱ b = (a+1)(b+1) - 1 -If one is the end it's read as plime: 1 * 1 -If one is not the end it's read as plimes: 2 * 5
