从坐标读价钱 = baca harga daripada koordinat 从原点出发，往右走第一个数字的格数，再往上走第二个数字的格数，看停在哪一件东西，再读它的价钱。 例子：(4, 1) 是往右 4、往上 1。 注意：次序不能反，先横后竖；找到东西以后，要读它旁边写的价钱。

reading a price from a coordinate = baca harga daripada koordinat Start at the origin, move right by the first number and up by the second, see which item you stop at, and read its price. Example: (4, 1) is 4 right and 1 up. Watch out: do not swap the order: across first, then up; once you find the item, read the price written beside it.

比的问题 = masalah nisbah 1 : 7 表示男生 1 份，女生 7 份。女生的人数是 7 份的总数，先求 1 份。 例子：比 1 : 2，大的是 30，1 份是 15。 注意：男生比女生少，答案应该比较小。

a ratio problem = masalah nisbah 1 : 7 means the boys are 1 part and the girls 7 parts. The number of girls is the total of 7 parts, so find 1 part. Example: with a ratio of 1 : 2 and the larger amount 30, 1 part is 15. Watch out: there are fewer boys, so the answer should be smaller.

比较单价 = bandingkan harga seunit 两间店的盒数不一样，要先求一盒的价钱，再比较哪一个便宜。 例子：甲 2 个 RM5（1 个 RM2.50），乙 3 个 RM6（1 个 RM2），乙比较便宜。 注意：不要只看总价，总价便宜不一定每一盒都便宜。

comparing unit prices = bandingkan harga seunit The shops sell different numbers of boxes, so find the price of one box first, then see which is cheaper. Example: X sells 2 for RM5 (RM2.50 each) and Y sells 3 for RM6 (RM2 each), so Y is cheaper. Watch out: do not compare only the totals; a cheaper total does not mean each box is cheaper.
