Exercise 4C Q14 - Q17 | Integers & Real Numbers | Think New Syllabus 8th Edition Oxford

In this video, we dive deep into Chapter 4: Integers, Rational Numbers, and Real Numbers from the Think New Syllabus Mathematics 8th Edition (Oxford). We provide step-by-step solutions for Exercise 4C, Questions 14, 15, 16, and 17. Whether you are struggling with complex order of operations (BODMAS/PEMDAS) or word problems involving negative marks and dice scores, this tutorial will help you achieve your "Vector Victory!" What we cover in this video: Q14: Evaluating complex integer expressions (Powers, Roots, and Brackets). Q15: Solving Mathematics Olympiad word problems (Negative marking logic). Q16: How to verify your complex calculations using a calculator. Q17: Real-world application: Calculating scores based on dice rolls and prime number conditions. Questions Solved in This Video: Question 14: Evaluate the following: (a) 24 \times (-2) \times 5 + (-6) (b) 4 \times 10 - 13 \times (-5) (c) 160 \div \sqrt[3]{-8} - 20 + (-5) (d) sqrt{5^2 - 3^2} - (57 - 77) \div 2 (e) [(12 - 18) \div 3 - (-1)] \times (-4)^3 (f) (5 - 2)^3 \times 2 + [-4 + (-7)] + (-2 + 4)^2 (g) [-10 - \{12 + (-3)^2\} + 3^2] + (-3) (h) \sqrt{-2 \times (-37) - [-2(-3) + 8 \times (-2) - 8 \times 2] + 5^2} Question 15: In a mathematics Olympiad, a correct answer is awarded 3 marks, but a wrong answer is awarded -1 mark. If no answer is given, 0 marks will be awarded. Albert took part in this Olympiad. There were 30 questions. He answered 17 questions correctly and 5 questions wrongly. How many marks did he score? Question 16:Use a calculator to check your answers to Question 14. Question 17:A six-sided die is rolled. If it shows a prime number that is odd, 5 points are awarded. If it shows a prime number that is even, 9 points will be deducted. If it shows any other number, 0 points will be awarded. The table shows how many times each number is obtained when Shaha rolls the die 20 times. (Calculations based on the frequency table provided in the book).
