Calculate 计算
A calculator and some working will be needed。需要用到计算器,并且体现计算步骤。
Change 转换
Usually convert from one unit to another;either using known metric unit conversions or the use of a conversion graph。一般是单位换算的问题。比如Change 35 cm to mm.
Complete 完成
Fill in missing values.填空,补充缺失的数据。
Describe 描述
Write a sentence that gives the features ofthe situation。书写一个句子来描述问题中的情况
Draw 画图
Produce an accurate drawing (unless asketch is being drawn。精确作图。比如说给定一个函数,在坐标系中精确画出对应的图像,而不是画草图。
Draw a sketch of 做草图
Produce a drawing that does not have to bedrawn to scale or a graph that is drawn without working out each coordinate。画一个草图,不必要依照准确的比例,或者不需要通过精确地点坐标来作图,一般是趋势图、示意图。
Expand 展开
Remove brackets。意思就是去掉表达式中的括号。
Expand and simplify 展开和化简
Remove brackets and the collect like terms。展开表达式,去掉表达式中的括号,并且合并同类项,化简表达式。
Explain 解释

Express 表达
Re-write in another form, some working maybe needed。重新写成另一种形式,可能需要书写步骤。
Factorise 因式分解
Insert brackets by taking out commonfactors。通过提取全部公因式来对表达式插入括号
Factorise fully 完全因式分解
Insert brackets by taking out all the common factors。通过提取全部公因式来对表达式插入括号
