? WRITING EQUATIONS AND ANSWERS CORRECTLY


This forum uses plain text, not LaTeX, so please format equations using scientific notation and simple symbols.

1️⃣ Powers and Roots 
Use the caret (^) for powers and sqrt() for roots. 
Examples: 
• 10^2 = 100 
• A = π * r^2 
• c = sqrt(a^2 + b^2)

2️⃣ Scientific Notation 
Large or small numbers should use E notation (“×10 to the power of”). 
Examples: 
• 3.0×10^8 → write as 3.0E8 
• 6.67×10^-11 → write as 6.67E-11 
• 1.6×10^-19 → write as 1.6E-19

3️⃣ Common Symbols 
| Concept | Symbol | Example | 
|----------|---------|---------| 
| Multiply | * | F = m * a | 
| Divide | / | v = d / t | 
| Power | ^ | E = m * c^2 | 
| Root | sqrt() | sqrt(4) = 2 | 
| Delta/change | Δ or d | ΔT = 5°C | 
| Approximation | ≈ or ~ | π ≈ 3.14 |

You can copy Unicode characters like Δ, μ, Ω, ° directly into posts. 

4️⃣ Code Blocks 
Use

Code:

tags to preserve spacing: 
[code]
F = (G * m1 * m2) / r^2
a = F / m

5️⃣ Example Formulas 

Code:

1. Newton’s Second Law:
  F = m * a

2. Gravitational Force:
  F = (6.67E-11 * m1 * m2) / r^2

3. Ideal Gas Law:
  P * V = n * R * T

Good Practice: 
✔ Always explain symbols the first time you use them. 
✔ Include units. 
✔ Focus on clarity over style.
