๐ข Algebra Fundamentals
What is Algebra?
Algebra uses letters (called variables) to represent unknown numbers. It helps us solve problems and find patterns!
Think of it this way:
If you have 3 boxes of cookies and each box has x cookies, you have 3x cookies total!

๐ฏ Understanding Probability
Probability measures how likely an event is to happen, from 0 (impossible) to 1 (certain).
๐ฒ Example: Rolling a Die
What's the probability of rolling a 3?
- Favorable outcomes: 1 (just the number 3)
- Total outcomes: 6 (numbers 1-6)
- Probability = 1/6 โ 0.167 or about 16.7%
