分解再乘 = cerakin dan darab 把金额分成整千和剩下的部分，两部分分别乘七，再把两个积加起来。最后看答案卡时，一位一位对照，因为有的卡只是把数字调换了位置。 例子：3 × RM1 200 = 3 × RM1 000 + 3 × RM200 = RM3 000 + RM600 = RM3 600。 注意：零头那一部分也要乘七，漏乘它会得到太小的数。

break up and multiply = cerakin dan darab Split the amount into whole thousands and the rest, multiply each part by 7 and add the two products. When checking the answer cards, compare digit by digit, because some cards only swap digits around. Example: 3 × RM1 200 = 3 × RM1 000 + 3 × RM200 = RM3 000 + RM600 = RM3 600. Watch out: the smaller part must be multiplied by 7 too; missing it gives an amount that is too small.

从整数金额减 = tolak daripada ringgit bulat 被减的金额是整数令吉，先写成点零零。仙和个位、十位、百位都是零，要一路向左借，借过的零变成九。算完用加法检查：差加上减去的金额，要刚好等于原来的金额。 例子：RM5 000 − RM1 250.50 = RM3 749.50，检查 RM3 749.50 + RM1 250.50 = RM5 000。 注意：一路借位时，每一位都要改对，最常错的是千位忘了少一。

subtract from whole ringgit = tolak daripada ringgit bulat The first amount is whole ringgit, so write it with .00. The sen, ones, tens and hundreds are all zero, so borrow all the way along; the zeros passed over become 9. Check by adding: the difference plus the amount taken away must equal the starting amount. Example: RM5 000 − RM1 250.50 = RM3 749.50; check RM3 749.50 + RM1 250.50 = RM5 000. Watch out: change every place when borrowing along; the thousands place forgetting to drop by 1 is the most common slip.
