Mathematical terms often have meanings that differ significantly from their everyday usage.

For Example:
  1. Mean
    • Common usage: Refers to being unkind or cruel.
      “He was mean to his little brother.”
    • Mathematical meaning: In statistics, mean is the average of a set of numbers, calculated by dividing the sum of the numbers by the count of values.
  2. Plane
    • Common usage: Refers to an aircraft or a flat surface.
      “We traveled to the city by plane.”
    • Mathematical meaning: In geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions. It has no thickness but is conceptually infinite.
  3. Right
    • Common usage: Refers to being correct, or to a direction opposite of left.
      “You got the right answer.”, “Turn right at the intersection.”
    • Mathematical meaning: In geometry, right refers to a 90-degree angle, such as in a right triangle, where one of the angles measures exactly 90 degrees.
Understanding these terms accurately is crucial for solving problems effectively. This learning dictionary is designed to help students who are unfamiliar with mathematical terminology in English by providing clear explanations, concept examples, and related problems. It aims to bridge the gap between language and mathematical understanding, making it easier to grasp the underlying concepts.

Your explanation looks well-written and clear! It effectively conveys the importance of understanding the distinct meanings of mathematical terms and encourages students in a positive tone. Below is the Korean translation:
수학 용어는 일상적인 사용과는 크게 다른 의미를 가지는 경우가 많습니다.
예를 들어, "He was mean to his little brother."에서 mean은 불친절하거나 못된 행동을 가리킵니다. 하지만, 수학적으로는 통계학에서 평균은 숫자의 집합의 합을 값의 개수로 나누어 계산된 평균을 의미합니다.

이러한 용어를 정확히 이해하는 것은 문제를 효과적으로 해결하는 데 매우 중요합니다. 이 사전은 영어로 된 수학 용어에 익숙하지 않은 학생들이 명확한 설명, 개념 예시, 관련 문제를 통해 이해를 도울 수 있도록 설계되었습니다. 언어와 수학적 이해의 간극을 줄이고, 기본 개념을 더 쉽게 파악할 수 있도록 돕기 위한 목적입니다.

이 자료가 여러분이 학습을 즐기고, 좋은 성적을 거두고, 무엇보다도 수학 공부에서 즐거움을 찾는 데 도움이 되기를 바랍니다.
