Page 3: Advanced Problem-Solving Techniques
This final page focuses on advanced problem-solving techniques, essential for 8th grade mathematics achievement tests and preparing for the LGS exam.
The page starts with a geometric problem involving two squares, combining concepts of perimeter, area, and algebraic equations.
Example: Two squares with a total perimeter of 16 cm and a difference in side lengths of 4 cm are used to calculate a shaded area.
Next, the guide presents a challenging number theory problem:
1001² - 999² = ?
Highlight: This problem demonstrates the application of the difference of squares formula in a non-algebraic context, a common technique in new generation math questions.
The page then explores problems involving irrational numbers and algebraic manipulation:
√2−1² = a + b√2
Vocabulary: "Tam sayılar" integers are used in this context to represent a and b.
The final section includes problems that combine multiple concepts, such as solving systems of equations and working with complex fractions.
Definition: A system of equations involves two or more equations that must be solved simultaneously.
This page emphasizes the importance of integrating various mathematical skills to solve complex problems, preparing students for high-level 8th grade math tests and beyond.
