hanh trung » thanh trung, hanh trang, manh trung
mot chieu » doi chieu

luong tai » dung tai, luong va
ho chieu » theo chieu, doi chieu, thi chieu
tai toan » bai toan, tap toan, tai tuan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((mot chieu) OR (ho chieu))) OR (hoc thieu)) tinh - hanh trung cua thong luong tai toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((mot chieu) OR (ho chieu))) or (hoc thieu)) tinh - hanh trung cua thong luong tai toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((((mot chieu) OR (ho chieu))) or (hoc thieu)) tinh - hanh trung cua thong luong tai toan ban*.
