RM78 540 − RM4 926 = ?
对齐数位 = susun ikut nilai tempat 被减数是五位数,减数只有四位数。列竖式时个位对个位,减数的万位空着。从个位减起,不够减就向左边借一,每借一次左边那一位就少一。 例子:RM56 300 − RM2 150 = RM54 150。 注意:如果把四位数靠左对齐,每一位都会错位,差会小得不合理。
line up the places = susun ikut nilai tempat The first number has five digits and the second has only four. Put ones under ones and leave the ten thousands of the smaller number empty. Subtract from the ones and borrow when a digit is too small; the place on the left goes down by 1 each time. Example: RM56 300 − RM2 150 = RM54 150. Watch out: lining the four-digit number up on the left shifts every place and gives a difference that is far too small.

RM86 413.90 − RM25 708.45 = ?
带仙减法 = tolak ringgit dan sen 两个金额都有仙,小数点对齐后从最右边的一仙位开始减。仙的部分算完再算令吉。这题在个位和百位都会遇到不够减的情况,要向左边借一,借过的那一位记得少一。 例子:RM5 210.80 − RM1 105.35 = RM4 105.45。 注意:借位以后在上面写下新的数字,才不会忘记那一位已经少了一。
subtracting ringgit and sen = tolak ringgit dan sen Both amounts have sen. Line up the points and start from the rightmost sen digit, finish the sen, then do the ringgit. In this question the ones and the hundreds are both too small, so borrow from the left and remember that place is now 1 less. Example: RM5 210.80 − RM1 105.35 = RM4 105.45. Watch out: write the new digit above each place you borrow from so you do not forget it has gone down.

RM90 000 − RM1 234.60 − RM38 507.15 = ?
连减两次 = tolak dua kali 算式里有两个减号,要从左到右做两步:第一步用最前面的金额减去中间的金额,得到中间结果;第二步用中间结果再减去最后面的金额。最前面的金额是整数令吉,要写成点零零。 例子:RM5 000 − RM500 − RM1 200.50,先得 RM4 500,再得 RM3 299.50。 注意:做完第一步不要停,中间结果还要再减一次。
subtract twice = tolak dua kali There are two minus signs, so work left to right in two steps: first subtract the second amount from the first to get a middle result, then subtract the third amount from that. The first amount is whole ringgit, so write it with .00. Example: RM5 000 − RM500 − RM1 200.50; first RM4 500, then RM3 299.50. Watch out: do not stop after step 1; the middle result still has to be subtracted again.
Soalan 4 / 6Latihan tambahan
RM45 316 − □ = RM30 000. □ = ?
求减数 = cari nilai yang ditolak 方框是被拿走的金额。原来的金额减去方框,剩下题目给的金额,所以方框等于原来的金额减去剩下的金额。算好后代回去检查:原来的金额减方框,要刚好得到剩下的数。 例子:RM2 480 − □ = RM2 000,□ = RM2 480 − RM2 000 = RM480。 注意:方框一定比原来的金额小;如果比原来的还大,就是错用了加法。
find the amount taken away = cari nilai yang ditolak The box is the amount taken away. The starting amount minus the box leaves the given amount, so the box is the starting amount minus what is left. Put it back to check that the subtraction really leaves that amount. Example: RM2 480 − □ = RM2 000, so □ = RM2 480 − RM2 000 = RM480. Watch out: the box must be smaller than the starting amount; a bigger answer means addition was used by mistake.

Puan Lina ada RM12 500. Dia membeli peti sejuk RM2 899 dan mesin basuh RM1 649.90. Berapakah baki wangnya?
剩下多少钱 = baki wang 莉娜女士买了两样电器,两笔钱都付出去了,所以原来的钱要减两次。可以一个一个减,也可以先把两样电器的价钱加起来再一次减掉,两种方法结果相同。 例子:RM3 000 − RM800 − RM450.50 = RM1 749.50,或 RM3 000 − RM1 250.50 = RM1 749.50。 注意:只减一样电器的价钱,剩下的钱会多算。
money left = baki wang Puan Lina buys two appliances and pays for both, so the starting money is reduced twice. Subtract one price at a time, or add the two prices first and subtract once; both ways give the same answer. Example: RM3 000 − RM800 − RM450.50 = RM1 749.50, or RM3 000 − RM1 250.50 = RM1 749.50. Watch out: taking away only one appliance leaves too much money.

Kira dahulu.
P = RM9 000 − RM2 450.50
Q = RM8 000 − RM1 200
S = RM7 500 − RM350.75
Susun jawapan dalam tertib menurun.
降序 = tertib menurun 这题要先把三道减法都算出来,再比较三个差的大小,按从大到小的次序排好。比较金额时先比万位、千位,千位一样再比百位,一直比到仙。注意不能只看被减的数哪个大,因为减掉的也不一样。 例子:RM900 − RM100 = RM800,RM700 − RM50 = RM650,RM1 000 − RM400 = RM600,降序是 RM800、RM650、RM600。 注意:降序是从最大排到最小,升序才是从最小开始。
descending order = tertib menurun First work out all three subtractions, then compare the three answers and arrange them from biggest to smallest. Compare the thousands first; if they are the same, compare the hundreds, and so on down to the sen. Do not judge only by the first amount, because the amounts taken away are different too. Example: RM900 − RM100 = RM800, RM700 − RM50 = RM650, RM1 000 − RM400 = RM600; in descending order RM800, RM650, RM600. Watch out: descending starts with the biggest value; ascending starts with the smallest.
