📚 Essential Maths Book 7F: Compressed Question Types Explained | 核心数学练习册7F：核心题型全解析

The Essential Maths Book 7F for Key Stage 3 covers a broad range of foundation topics. This compressed review highlights the most common question types found in the book, from place value and arithmetic to algebra, geometry, and data handling. Working through these examples will help Year 7 students master key skills and prepare confidently for tests.

针对 KS3 编写的 Essential Maths Book 7F 覆盖了广泛的基础主题。这篇浓缩复习梳理了书中最常见的题型，涉及位值、算术、代数、几何和数据处理。通过练习这些精选例题，七年级学生能够掌握核心技能，并为考试做好充分准备。

1. Whole Numbers and Place Value | 整数与位值

Typical questions ask you to read and write large numbers, such as ‘Write 560 082 in words’ or ‘What is the value of the digit 7 in 3 472 105?’. The answer to the second question is 70 000, because the 7 is in the ten-thousands place. You must understand place value columns: millions, hundred-thousands, ten-thousands, thousands, hundreds, tens and units.

常见题型要求读、写大数，例如 ‘用文字写出 560 082’ 或 ‘数字 3 472 105 中，数位 7 的值是多少？’。第二题的答案是 70 000，因为 7 在万位上。你必须理解各个位值：百万、十万、万、千、百、十、个。

Multiplying and dividing by 10, 100 or 1000 is another key skill. When you multiply a whole number by 100, each digit moves two place value columns to the left, and you can simply write two zeros at the end. For example, 34 × 100 = 3400. For decimals, move the decimal point right: 5.6 × 100 = 560.

乘或除以 10、100、1000 是另一项核心技能。当你把整数乘以 100，每个数字向左移动两个位值，可以直接在末尾加两个零。例如，34 × 100 = 3400。对于小数，把小数点右移：5.6 × 100 = 560。

2. Addition, Subtraction, Multiplication, Division | 加减乘除

Foundation exercises require formal written methods: column addition, column subtraction, short and long multiplication, and short division. For addition, align the numbers by place value and carry when a column totals 10 or more. A question like ‘Calculate 345 + 678’ works step by step: 5+8=13, write 3 carry 1; 4+7+1=12, write 2 carry 1; 3+6+1=10, so the total is 1023.

基础练习要求使用标准的笔算方法：竖式加法、竖式减法、短乘/长乘法、短除法。加法时，按位值对齐数字，当某一位之和为 10 或更多时需进位。如 ‘计算 345 + 678’ 逐步运算：5+8=13，写 3 进 1；4+7+1=12，写 2 进 1；3+6+1=10，总和为 1023。

Multiplication by a two-digit number involves multiplying by tens and units separately. For 23 ×
