Berapakah panjang lidi ini?

量竹签 = ukur lidi 竹签的左端不在零,先把左端读准:找到最近的数字再数小格。右端也照样读。两个读数相减,差就是竹签的长度。 例子:从 22 mm 到 57 mm,长 57 − 22 = 35 mm。 注意:左端过了数字以后还有小格,别漏掉。
measuring a stick = ukur lidi The left end of the stick is not at zero, so read it carefully: find the nearest number and count the small spaces. Read the right end the same way. The difference between the two readings is the length. Example: from 22 mm to 57 mm is 57 − 22 = 35 mm. Watch out: there are small spaces after the number at the left end too.

Berapakah panjang bulu ayam ini?

读数过百 = bacaan melebihi 100 右端的读数超过了 100 也一样:先读出左右两端的读数,再用大的减小的。也可以从左端开始,每 10 mm 跳一次,最后加上剩下的小格。 例子:从 70 mm 到 115 mm,长 115 − 70 = 45 mm。 注意:读到 100 以后,数字是三位数。
readings past 100 = bacaan melebihi 100 It works the same when the right end is past 100: read both ends, then subtract the smaller from the bigger. You can also jump 10 mm at a time from the left end and add the small spaces left over. Example: from 70 mm to 115 mm is 115 − 70 = 45 mm. Watch out: after 100, the readings have three digits.
Soalan 3 / 4Latihan tambahan
Sebatang pensel diletakkan dari 27 mm hingga 92 mm. Berapakah panjangnya?
用读数求长度 = cari panjang daripada bacaan 题目给了起点和终点两个读数。长度等于终点减起点。个位不够减的时候,从十位借一当十,再减。 例子:从 36 mm 到 81 mm,长 81 − 36 = 45 mm。 注意:借位以后,十位要少一。
length from readings = cari panjang daripada bacaan The question gives the start and end readings. The length is end minus start. If the ones digit is too small, regroup one ten as ten ones, then subtract. Example: from 36 mm to 81 mm is 81 − 36 = 45 mm. Watch out: after regrouping, the tens digit goes down by one.
Soalan 4 / 4Latihan tambahan
Panjang reben 38 mm. Hujung kirinya pada 15 mm. Hujung kanannya pada tanda berapa?
倒过来想 = fikir secara songsang 这题知道长度和起点,要找终点。终点在起点的右边,比起点多出一整段长度,所以用起点的读数加上长度。算好后,可以用终点减起点检查是不是等于长度。 例子:长 24 mm、起点在 30 mm,终点在 30 + 24 = 54 mm。 注意:找终点要用加法,不是减法。
thinking backwards = fikir secara songsang Here the length and the start are known, and the end is missing. The end is to the right of the start, further along by the whole length, so add the length to the start reading. Then check: end minus start should equal the length. Example: a length of 24 mm starting at 30 mm ends at 30 + 24 = 54 mm. Watch out: finding the end needs adding, not subtracting.
