To be good in mathematics, one needs to

Options

A. create and formulate problems through abstract thinking and logical reasoning
B. memorise formulae
C. remember solutions
D. have mastery over calculations

Answer

To solve the question "To be good in Mathematics, one needs to...", we will analyze the provided options step by step.

### Step 1: Understand the Question
The question asks what is essential to be good in Mathematics. We need to evaluate each option based on its relevance to mathematical skills.

**Hint:** Think about the skills that contribute to success in Mathematics.

### Step 2: Evaluate Option A
Option A states: "create and formulate problems through abstract thinking and logical reasoning."
- This option emphasizes the importance of problem formulation and reasoning, which are critical skills in Mathematics. Being able to think abstractly and logically is fundamental to solving mathematical problems.

**Hint:** Consider how abstract thinking and logical reasoning are used in solving mathematical problems.

### Step 3: Evaluate Option B
Option B states: "memorize formulae."
- While knowing formulas can be helpful, Mathematics is not solely about memorization. Rote learning does not contribute to a deep understanding of mathematical concepts.

**Hint:** Reflect on whether understanding concepts is more important than memorizing them.

### Step 4: Evaluate Option C
Option C states: "remember solutions."
- Similar to option B, simply remembering solutions does not help in understanding how to arrive at those solutions. Problem-solving requires applying concepts rather than just recalling answers.

**Hint:** Think about the process of solving problems rather than just the end result.

### Step 5: Evaluate Option D
Option D states: "have mastered your calculations."
- While calculation skills are important, making mistakes is part of the learning process in Mathematics. Mastery of calculations alone does not encompass the broader skills needed in Mathematics.

**Hint:** Consider how making mistakes can lead to learning and improvement in Mathematics.

### Conclusion
After evaluating all options, we conclude that **Option A** is the best choice. It highlights the importance of abstract thinking and logical reasoning, which are essential for excelling in Mathematics.

**Final Answer:** Option A: create and formulate problems through abstract thinking and logical reasoning.
