kira petak = 数格子 长条有 10 格，每格是 0.1。蓝色的格子表示第一个数，橙色的格子表示第二个数。把两种颜色的格子一起数，数到几格，就是几个 0.1，再把它写成小数。 例子：蓝 1 格、橙 7 格 → 0.1 + 0.7 = 0.8。 注意：不要把两个数字并排写在一起，0.3 和 0.6 合起来不是 0.36。

kira petak = count the boxes The strip has 10 boxes and each box is 0.1. The blue boxes show the first number and the orange boxes show the second number. Count both colours together; that many tenths is the answer, written as a decimal. Example: 1 blue and 7 orange → 0.1 + 0.7 = 0.8. Watch out: do not write the two digits side by side; 0.3 and 0.6 together are not 0.36.

tempat perseratus = 百分位 0.07 的 7 在百分位，0.6 的 6 在十分位，两个数字不在同一位，不能直接相加。先把 0.6 写成 0.60，对齐小数点，再把同一位的数字相加。 例子：0.03 + 0.4 → 0.03 + 0.40 = 0.43。 注意：把 6 和 7 直接相加，是把十分位和百分位混在一起了。

tempat perseratus = hundredths place In 0.07 the 7 is in the hundredths place, but in 0.6 the 6 is in the tenths place. Different places cannot be added together directly. Write 0.6 as 0.60, line up the decimal points, then add digits in the same place. Example: 0.03 + 0.4 → 0.03 + 0.40 = 0.43. Watch out: adding the 6 and the 7 straight away mixes up tenths and hundredths.

masalah harian = 应用题 题目问一共多重，所以把两个质量加起来。用竖式算：百分位加起来超过 9，要写个位数字，再向十分位进 1；十分位要记得加上进上来的 1。最后写上单位 kg。 例子：0.46 kg + 0.38 kg = 0.84 kg。 注意：忘了进位，答案会少了 0.1。

masalah harian = word problem The question asks for the total mass, so add the two masses. Use the column method: the hundredths add up to more than 9, so write the ones digit and carry 1 to the tenths. Remember to add that carried 1 in the tenths, then write the unit kg. Example: 0.46 kg + 0.38 kg = 0.84 kg. Watch out: forgetting to carry makes the answer 0.1 too small.

lompatan = 跳跃 在数线上往右跳就是加。跳一次 0.10，十分位加 1，百分位不变；跳三次就要加 3 个十分之一。最后再跳 0.04，只改变百分位。把每一次落点按顺序写下来，就不容易数错。 例子：从 0.21 跳两次 0.10，再跳 0.05 → 0.46。 注意：三次 0.10 都要跳完，不能只跳一次。

lompatan = jump Jumping to the right on a number line means adding. Each jump of 0.10 adds 1 to the tenths and leaves the hundredths alone, so three jumps add 3 tenths. The last jump of 0.04 changes only the hundredths. Write down each landing point in order. Example: from 0.21 jump 0.10 twice, then 0.05 → 0.46. Watch out: make all three jumps of 0.10, not just one.

petak berwarna = 涂色的格子 百格一共 100 小格，每小格是 0.01。先数蓝色的格子；橙色的 0.7 要先写成两位小数，看看它占多少小格。把两种颜色的格子数加起来，再写成两位小数。 例子：蓝 26 格、橙 40 格 → 0.26 + 0.4 = 0.66。 注意：0.7 是 7 整横行，不是 7 小格。

petak berwarna = shaded squares The hundred grid has 100 small squares and each one is 0.01. Count the blue squares first. For the orange part, write 0.7 with two decimal places to see how many small squares it covers. Add the two counts and write the total with two decimal places. Example: 26 blue and 40 orange → 0.26 + 0.4 = 0.66. Watch out: 0.7 is 7 whole rows, not 7 small squares.

anu dalam ayat tambah = 加法里的未知数 加法算式里缺一个加数，就用和减去已知的加数。这里要把 0.3 写成 0.30，对齐小数点再减。求出答案后，用加法检查一次。 例子：0.4 + □ = 0.96 → 0.96 − 0.40 = 0.56。 注意：0.3 是 3 个十分之一，不是 3 个百分之一，减的时候要减在十分位。

anu dalam ayat tambah = unknown in an addition sentence When an addend is missing, subtract the known addend from the sum. Write 0.3 as 0.30, line up the decimal points and subtract. Then add to check your answer. Example: 0.4 + □ = 0.96 → 0.96 − 0.40 = 0.56. Watch out: 0.3 is 3 tenths, not 3 hundredths, so take it away from the tenths digit.

digit tersembunyi = 被盖住的数字 先算百分位：两个百分位数字相加，满 10 就只写个位，向十分位进 1。再看十分位：□、另一个十分位数字和进上来的 1，加起来要等于答案的十分位。用减法求出 □，最后把整题加一次检查。 例子：0.□6 + 0.18 = 0.54 → 6 + 8 = 14 进 1，□ + 1 + 1 = 5 → □ = 3。 注意：别忘了进上来的 1，否则会多算 1。

digit tersembunyi = hidden digit Start with the hundredths: if the two digits make 10 or more, write the ones digit and carry 1 to the tenths. In the tenths, the box, the other tenths digit and the carried 1 must add up to the tenths digit of the answer. Subtract to find the box, then add the whole sum to check. Example: 0.□6 + 0.18 = 0.54 → 6 + 8 = 14, carry 1; □ + 1 + 1 = 5 → □ = 3. Watch out: include the carried 1, or your digit will be 1 too big.
