Get Ahead in 12th Business Maths Exercise 6.2 with Detailed Solutions

Introduction

Are you struggling to solve the Exercise 6.2 problems in your 12th grade Business Maths syllabus? Don’t worry, we’ve got you covered! In this article, we will provide detailed solutions to the Exercise 6.2 questions, along with insights on how to approach similar problems in the future. Mastering Exercise 6.2 will not only help you in your exams but also give you a solid foundation in mathematics, which is essential for various career paths.

Understanding Exercise 6.2

Exercise 6.2 is centered around the concept of Matrices. Matrices are rectangular arrays of numbers, symbols, or expressions arranged in rows and columns. Exercise 6.2 comprises questions that cover Matrix operations such as addition, subtraction, transposition, and multiplication. These are essential concepts that have wide applications in various fields like physics, engineering, and computer science.

Matrix Addition

Question 1 of Exercise 6.2 deals with Matrix addition. To add two matrices, we need to add their corresponding elements. For example, if A and B are two matrices of the same order (same number of rows and columns), then A + B will be a resultant matrix, where each element is the sum of the corresponding elements of A and B.

Example:

A = [1 2 3; 4 5 6; 7 8 9]

B = [9 8 7; 6 5 4; 3 2 1]

A+B = [10 10 10; 10 10 10; 10 10 10]

Matrix Multiplication

Question 2 of Exercise 6.2 covers Matrix multiplication. To multiply two matrices, we need to follow a specific rule. Suppose A and B are two matrices, where A is of order m x n, and B is of order n x p, then the resultant matrix AB will be of order m x p.

Example:

A = [1 2 3; 4 5 6]

B = [1 4; 2 5; 3 6]

AB = [14 32; 32 77]

Insights and Tips

Here are some tips that will help you get ahead in Exercise 6.2:

– Practice regularly: The more you practice, the better you’ll get at solving Matrix problems.

– Understand the concepts: Don’t just memorize solutions; try to understand why and how they work.

– Use diagrams: Diagrams can help you visualize the problem and make it easier to solve.

Conclusion

In conclusion, Exercise 6.2 is a crucial part of the 12th-grade Business Maths syllabus that covers Matrix operations. By mastering these concepts, you’ll not only score good grades in your exams but also develop a strong foundation in mathematics that will help you in various career paths. Remember to practice regularly, understand the concepts, and use diagrams to get ahead in Exercise 6.2.
