Concept:The highest aim of mathematics is to develop the ability to think mathematically, which includes logical discussion, understanding abstractness, and mathematical thinking.
Explanation:According to NCF-2005, the main goal of mathematics education is mathematization of children's minds.
George Polya described two kinds of aims: broader and narrower.
The higher aim is to develop resources for logical reasoning, handling abstraction, and pursuing assumptions to conclusions.
This includes problem-solving, logical discussion, use of heuristics, estimation, optimization, patterns, visualization, reasoning, proof, and mathematical communication.
All these skills together form the highest aim of mathematics.
Therefore, logical discussion, understanding abstractness, and mathematical thinking are all part of this higher aim.
Answer:D. All of the above
