Soalan 1 / 2Latihan tambahan
2 × 3 hari 10 jam = ?
天和小时的乘法 = darab hari dan jam 用乘数分别乘小时和天。乘完先看小时栏:满二十四就换出一天加到天那一栏;不满二十四,小时就保持原样,不必进位。 例子:3 × 1 天 5 小时 → 3 天 15 小时(十五小时不满一天,不进位)。 注意:不是每一题都要进位,要先检查小时有没有满二十四。
multiplying days and hours = darab hari dan jam Multiply the hours and the days by the number. Then look at the hours: if they reach 24, change 24 hours into a day in the days column; if not, leave them as they are. Example: 3 × 1 day 5 hours → 3 days 15 hours (15 hours is less than a day, so no regrouping). Watch out: not every question needs regrouping; first check whether the hours reach 24.
Soalan 2 / 2Latihan tambahan
4 dekad 2 tahun − 9 tahun = ?
dekad 和年相减 = tolak dekad dan tahun 被减去的只有年,要写在年那一栏下面。年不够减,就向 dekad 借一个,换成十年加到年那一栏,dekad 少一;然后减年,dekad 照写。 例子:2 dekad 1 年 − 5 年 → 1 dekad 11 年 − 5 年 → 1 dekad 6 年。 注意:借了以后 dekad 要少 1;用下面的年去减上面的年是不对的。
subtracting decades and years = tolak dekad dan tahun Only years are taken away, so write them under the years column. If the years are not enough, borrow 1 dekad as 10 years, add them to the years and take 1 from the dekad; then subtract the years and copy the dekad. Example: 2 dekad 1 year − 5 years → 1 dekad 11 years − 5 years → 1 dekad 6 years. Watch out: after borrowing the dekad are 1 less, and taking the top years from the bottom years is wrong.
