1. **Problem:** Prepare for your exam by understanding key math concepts clearly and simply. 2. **Irrational Numbers:** Numbers that cannot be written as fractions, like $\sqrt{5}$. 3. **Scientific Notation:** Express big or small numbers as $a \times 10^n$, where $1 \leq a < 10$ and $n$ is an integer. 4. **Algebra Basics:** Simplify expressions by combining like terms and using distributive property, e.g., $(x+5)(x+3) = x^2 + 8x + 15$. 5. **Inequalities:** Solve and graph inequalities like $2x - 10 \geq 14$ by isolating $x$. 6. **Geometry:** Use formulas like perimeter and area for shapes; e.g., perimeter of rectangle = $2(\text{length} + \text{width})$. 7. **Pythagoras' Theorem:** For right triangles, $a^2 + b^2 = c^2$ helps find side lengths. 8. **Fractions:** Add, subtract, multiply, and divide fractions by finding common denominators or multiplying across. 9. **Exponents:** Multiply powers with the same base by adding exponents: $x^{11} \times x^7 = x^{18}$. 10. **Percentages:** Increase by a percentage using multipliers, e.g., increase by 30% means multiply by 1.3. 11. **Practice:** Solve problems step-by-step, check your work, and review mistakes. Good luck on your exam!
