📚 KS3 CAIE Further Maths: Vocabulary Terms Quick Memorisation Guide | KS3 CAIE 进阶数学：词汇术语速记指南

Mastering mathematical vocabulary is essential for success in CAIE KS3 Further Maths. Understanding terms like ‘coefficient’ or ‘hypotenuse’ can dramatically improve problem-solving skills. This guide provides quick memorisation tips and mnemonics to help you remember key words effortlessly.

掌握数学词汇对于在CAIE KS3进阶数学中取得成功至关重要。理解诸如‘系数’或‘斜边’等术语能极大提高解题能力。本指南提供快速记忆技巧和助记符，助你轻松牢记关键词。

1. Algebraic Expressions and Equations | 代数表达式与方程

Term: Variable – a symbol, usually a letter, that stands for an unknown number. Quick memory tip: Think of ‘vary’ – because the value can vary.

术语：变量——通常用字母表示未知数。速记：联想 ‘vary’（变化），因为它会变化。

Term: Coefficient – the number part of a term that multiplies the variable. Mnemonic: ‘Co-‘ means together, so the coefficient works together with the variable.

术语：系数——与变量相乘的数的部分。助记：’Co-‘ 表示共同，所以系数与变量共同作用。

Term: Expression – a combination of terms and operators without an equals sign. Visual tip: ‘Ex-press-ion’ sounds like ‘express without equals’.

术语：表达式——由项和运算符组合而成，没有等号。形象记忆：’表达式’ 发音类似 ‘无等号的快递’。

Term: Equation – a mathematical statement showing two expressions are equal, always containing an equals sign. Spot the word ‘equal’ inside ‘equation’.

术语：方程——表明两个表达式相等的数学陈述，总是包含等号。在 ‘equation’ 里找到 ‘equal’。

Term: BIDMAS/BODMAS – the order of operations: Brackets, Indices (or Orders), Division, Multiplication, Addition, Subtraction. Rhyme: ‘BIDMAS tells you what to do first’.

术语：BIDMAS/BODMAS——运算顺序：括号、指数（或阶）、除法、乘法、加法、减法。助记口诀：’先算括号再指数，乘除之后加减除’。

2. Integers, Powers and Roots | 整数、幂与根

Term: Integer – a whole number (positive, negative or zero). Memory hook: ‘Inte-ger’ sounds like ‘intact’ – nothing broken, no fractions.

术语：整数——正整数、负整数或零。记忆钩子：’Integer’ 类似 ‘intact’（完整），无分数。

Term: Power (exponent) – the small raised number indicating repeated multiplication. e.g. 2³ means 2×2×2. Visual: the ‘power’ lifts the number up.

术语：幂（指数）——表示重复乘法的上标小数字。例如 2³ 表示 2×2×2。形象：’幂’ 把数字举高了。

Term: Square root – a value
