克减克 = gram tolak gram 个位 0 不够减 5,向十位借 1:10 − 5 = 5;十位 6 − 1 − 4 = 1;百位 7 − 3 = 4。答案 415 g。 例子:930 g − 214 g = 716 g。 注意:425 g 是个位倒过来 5 − 0;1 kg 105 g 是做成了加法。
grams minus grams = gram tolak gram The ones digit 0 is less than 5, so borrow a ten: 10 − 5 = 5; tens 6 − 1 − 4 = 1; hundreds 7 − 3 = 4. The answer is 415 g. Example: 930 g − 214 g = 716 g. Watch out: 425 g does 5 − 0 backwards in the ones, and 1 kg 105 g adds instead.

difference between the duck and the chicken = beza jisim itik dan ayam 3 kg 25 g − 2 kg 100 g. 25 is less than 100, so borrow 1 kg: 3 becomes 2 and the grams give 1 025 − 100 = 925; kilograms 2 − 2 = 0. The difference is 925 g, less than 1 kg. Example: 2 kg 50 g − 1 kg 300 g = 750 g. Watch out: 1 kg 75 g does 100 − 25 backwards; when the kilograms come to 0, write only the grams.

Ibu ada 10 kg beras. Ibu menggunakan 3 kg 450 g. Berapakah jisim beras yang tinggal?
剩下多少 = berapa yang tinggal 用掉了就用减法:10 kg − 3 kg 450 g。克栏 0 不够减,借 1 kg:10 变 9,1 000 − 450 = 550;公斤 9 − 3 = 6。还剩 6 kg 550 g。 例子:5 kg 面粉用了 1 kg 200 g,剩 3 kg 800 g。 注意:7 kg 550 g 借了位却没把 10 改成 9。
how much is left = berapa yang tinggal Using some up means subtracting: 10 kg − 3 kg 450 g. The gram column 0 is too small, so borrow 1 kg: 10 becomes 9 and 1 000 − 450 = 550; kilograms 9 − 3 = 6. There are 6 kg 550 g left. Example: 5 kg of flour with 1 kg 200 g used leaves 3 kg 800 g. Watch out: 7 kg 550 g borrows but does not change 10 to 9.
