1. Whole Number Computation | 整数运算
Question: Calculate 248 × 37. Answer: 9,176.
题目：计算 248 × 37。答案：9,176。
Break 37 into 30 and 7. First multiply 248 by 30 to get 7,440. Then multiply 248 by 7 to get 1,736. Add the two products: 7,440 + 1,736 = 9,176. A common mistake is forgetting to carry in the ones column.
将 37 拆分为 30 和 7。先计算 248 × 30 = 7,440，再计算 248 × 7 = 1,736。把两个积相加：7,440 + 1,736 = 9,176。常见错误是在个位进位时漏加。
Second question: Divide 1,872 by 24. Answer: 78.
第二题：计算 1,872 ÷ 24。答案：78。
Since 24 × 70 = 1,680 and 24 × 8 = 192, we have 1,680 + 192 = 1,872. Therefore the quotient is 70 + 8 = 78. Always check division by multiplying.
因为 24 × 70 = 1,680，24 × 8 = 192，所以 1,680 + 192 = 1,872。因此商为 70 + 8 = 78。做除法后务必用乘法验算。
2. Fractions and Decimals | 分数与小数
Question: Add 3/4 and 2/5. Answer: 23/20 or 1 3/20.
题目：计算 3/4 + 2/5。答案：23/20 或 1 3/20。
Find a common denominator. The lowest common multiple of 4 and 5 is 20. Convert: 3/4 = 15/20 and 2/5 = 8/20. Add the numerators: 15 + 8 = 23, so the sum is 23/20. Write as a mixed number: 1 3/20.
先找公分母。4 和 5 的最小公倍数是 20。通分：3/4 = 15/20，2/5 = 8/20。分子相加：15 + 8 = 23，所以和为 23/20。写成带分数就是 1 3/20。
Second question: Convert 0.625 into a fraction in its simplest form. Answer: 5/8.
第二题：把 0.625 化为最简分数。答案：5/8。
Write 0.625 as 625/1000. Divide both the numerator and denominator by 125 to simplify: 625 ÷ 125 = 5 and 1000 ÷ 125 = 8, giving 5/8. Recognising common decimal-fraction equivalents saves time.
把 0.625 写作 625/1000。分子分母同除以 125 化简：625 ÷ 125 = 5，1000 ÷ 125 = 8，得到 5/8。熟记常见小数与分数的换算可以节省时间。
