📒 The 1-minute cheat sheet
📌 Solve For X
- Do the SAME operation to BOTH sides
- Undo with the inverse: + ↔ −, × ↔ ÷
- 2x + 3 = 7 → 2x = 4 → x = 2
- Check by plugging your answer back in
📌 Order Of Operations (Pemdas)
- Parentheses → Exponents → Multiply/Divide → Add/Subtract
- Left to right within the same level
- 3 + 4 × 2 = 3 + 8 = 11 (not 14)
📌 Inequalities
- Solve like an equation
- FLIP the sign when you × or ÷ by a negative
- −2x < 6 → x > −3
✨Quick Tip
Focus on the highlighted terms — those are what the TEAS and HESI test most on algebra & solving equations.
