小时乘法 = darab jam 只有 jam 一个单位，用乘法表：9 × 6 = 54，答案 54 jam。 例子：7 jam × 4 = 28 jam。 注意：15 jam 是把乘号当成加号；56 jam 是乘法表背错了。

multiplying hours = darab jam There is only one unit, so use the times table: 9 × 6 = 54, giving 54 jam. Example: 7 jam × 4 = 28 jam. Watch out: 15 jam treats the times sign as a plus sign, and 56 jam is a times-table slip.

两倍 = darab 2 个位 8 × 2 = 16，写 6，进 1；十位 3 × 2 = 6，加 1 得 7。答案 76 minit，单位保持 minit。 例子：29 minit × 2 = 58 minit。 注意：66 minit 忘了加进位；40 minit 是做成了 38 + 2。

doubling = darab 2 Ones: 8 × 2 = 16, write 6 and carry 1; tens: 3 × 2 = 6, plus 1 makes 7. The answer is 76 minit, still in minutes. Example: 29 minit × 2 = 58 minit. Watch out: 66 minit forgets the carry, and 40 minit works out 38 + 2 instead.

秒乘 3 = darab saat dengan 3 4 × 3 = 12，写 2，进 1；6 × 3 = 18，加 1 得 19。答案 192 saat。 例子：52 saat × 3 = 156 saat。 注意：182 saat 忘了进位；1 minit 92 saat 把 100 当成 1 minit，可是 1 minit 只有 60 saat。

multiplying seconds by 3 = darab saat dengan 3 4 × 3 = 12, write 2 and carry 1; 6 × 3 = 18, plus 1 makes 19. The answer is 192 saat. Example: 52 saat × 3 = 156 saat. Watch out: 182 saat forgets the carry, and 1 minit 92 saat treats 100 as one minute, but a minute is only 60 seconds.

乘 7 = darab dengan 7 “27 minit 乘 7”。个位 7 × 7 = 49，写 9，进 4；十位 2 × 7 = 14，加 4 得 18。答案 189 minit。 例子：19 minit × 5 = 95 minit。 注意：149 minit 忘了加进位；1 jam 89 minit 把 100 当成 1 jam，1 jam 只有 60 minit。

multiplying by 7 = darab dengan 7 The question asks for 27 minit × 7. Ones: 7 × 7 = 49, write 9 and carry 4; tens: 2 × 7 = 14, plus 4 makes 18. The answer is 189 minit. Example: 19 minit × 5 = 95 minit. Watch out: 149 minit forgets the carry, and 1 jam 89 minit treats 100 as an hour, but an hour is only 60 minutes.

三位数乘法 = darab nombor tiga digit 个位 5 × 3 = 15，写 5，进 1；十位 1 × 3 = 3，加 1 得 4；百位 2 × 3 = 6。答案 645 saat。也可以用格子法：06、03、15 沿斜线相加。 例子：132 saat × 2 = 264 saat。 注意：635 saat 忘了进位；218 saat 是把乘法做成加法。

multiplying a 3-digit number = darab nombor tiga digit Ones: 5 × 3 = 15, write 5 and carry 1; tens: 1 × 3 = 3, plus 1 makes 4; hundreds: 2 × 3 = 6. The answer is 645 saat. The lattice method works too: 06, 03 and 15 added along the diagonals. Example: 132 saat × 2 = 264 saat. Watch out: 635 saat forgets the carry, and 218 saat adds instead of multiplying.

两位数小时 = jam dua digit 个位 6 × 6 = 36，写 6，进 3；十位 1 × 6 = 6，加 3 得 9。答案 96 jam。 例子：13 jam × 7 = 91 jam。 注意：66 jam 忘了加进位的 3；22 jam 是 16 + 6。

two-digit hours = jam dua digit Ones: 6 × 6 = 36, write 6 and carry 3; tens: 1 × 6 = 6, plus 3 makes 9. The answer is 96 jam. Example: 13 jam × 7 = 91 jam. Watch out: 66 jam forgets the carried 3, and 22 jam is 16 + 6.

分栏乘 = darab setiap lajur minit 栏：13 × 3 = 39；jam 栏：2 × 3 = 6。答案 6 jam 39 minit。 例子：1 jam 20 minit × 2 = 2 jam 40 minit。 注意：6 jam 13 minit 只乘了 jam；2 jam 39 minit 只乘了 minit。

multiplying each column = darab setiap lajur Minutes: 13 × 3 = 39; hours: 2 × 3 = 6. The answer is 6 jam 39 minit. Example: 1 jam 20 minit × 2 = 2 jam 40 minit. Watch out: 6 jam 13 minit multiplies only the hours, and 2 jam 39 minit multiplies only the minutes.

被乘 = didarab dengan “4 minit 11 saat 乘 5”。saat 栏：11 × 5 = 55；minit 栏：4 × 5 = 20。答案 20 minit 55 saat。 例子：2 minit 9 saat × 6 = 12 minit 54 saat。 注意：20 minit 11 saat 忘了乘 saat 栏；4 minit 55 saat 忘了乘 minit 栏。

multiplied by = didarab dengan The question means 4 minit 11 saat × 5. Seconds: 11 × 5 = 55; minutes: 4 × 5 = 20. The answer is 20 minit 55 saat. Example: 2 minit 9 saat × 6 = 12 minit 54 saat. Watch out: 20 minit 11 saat forgets the seconds column, and 4 minit 55 saat forgets the minutes column.

乘 8 = darab 8 minit 栏：7 × 8 = 56，比 60 小，照写；jam 栏：3 × 8 = 24。答案 24 jam 56 minit。 例子：2 jam 6 minit × 9 = 18 jam 54 minit。 注意：11 jam 15 minit 是每栏都加 8，不是乘 8；24 jam 7 minit 忘了乘 minit 栏。

multiplying by 8 = darab 8 Minutes: 7 × 8 = 56, below 60, so write it down; hours: 3 × 8 = 24. The answer is 24 jam 56 minit. Example: 2 jam 6 minit × 9 = 18 jam 54 minit. Watch out: 11 jam 15 minit adds 8 to each column instead of multiplying, and 24 jam 7 minit forgets the minutes column.
