arithmetic
의미: The branch of mathematics dealing with basic operations on numbers: addition, subtraction, multiplication, and division. As an adjective (pronounced ar-ith-MET-ic), it means relating to arithmetic.
Arithmetic is considered the most elementary branch of mathematics and underpins all higher mathematical study. The adjective form appears in terms like 'arithmetic mean' (the simple average) and 'arithmetic progression' (a sequence with a constant difference between terms). Note the pronunciation shift: the noun is a-RITH-me-tic, whilst the adjective is ar-ith-MET-ic. It collocates with 'mean,' 'progression,' 'sequence,' 'basic,' and 'mental.'
예문
- The arithmetic mean of 4, 8, and 12 is 8, calculated by summing the values and dividing by three. 4、8和12的算术平均数是8,通过将各值相加后除以3计算得出。La media aritmética de 4, 8 y 12 es 8, calculada sumando los valores y dividiendo entre tres.4、8、12の算術平均は8で、値を合計して3で割ることで求められます。4, 8, 12의 산술 평균은 8이며, 값을 모두 더한 뒤 3으로 나누어 구합니다.
- Primary school pupils are expected to master basic arithmetic before moving on to algebra. 小学生应在学习代数之前掌握基本的算术。Se espera que los alumnos de primaria dominen la aritmética básica antes de pasar al álgebra.小学生は代数に進む前に基本的な算術を習得することが求められています。초등학생은 대수학으로 넘어가기 전에 기본 산술을 숙달해야 합니다.
- An arithmetic progression with first term 3 and common difference 5 produces the sequence 3, 8, 13, 18. 首项为3、公差为5的等差数列产生数列3、8、13、18。Una progresión aritmética con primer término 3 y diferencia común 5 produce la secuencia 3, 8, 13, 18.初項3、公差5の等差数列は3、8、13、18という数列になります。초항이 3이고 공차가 5인 등차수열은 3, 8, 13, 18의 수열을 만듭니다.
