　　分數(shù)：fractions

　　分子：numerator

　　分母：denominator

　　分數(shù)的加減乘除：addition，subtraction，multiplication and division of fractions

　　繁分數(shù)和假分數(shù)：mixed number and improper fraction

　　繁分數(shù)是指一個數(shù)由一個整數(shù)和一個分數(shù)構(gòu)成。

　　假分數(shù)是指分子大于分母的分數(shù)。例如：7/3

　　小數(shù)：decimals

　　科學(xué)計數(shù)法：scientific notation

　　Sometimes decimals are expressed as the product of a number with only one digit to the lt of the decimal point and a power of 10. This is called scientific notation. For example, 231 can be written as 2.31×102 and 0.0231 can be written as 2.31×10-2. When a number is expressed in scientific notation, the exponent of the 10 indicates the number of places that the decimal point is to be moved in the number that is to be multiplied by a power of 10 in order to obtain the product. The decimal point is moved to the right if the exponent is positive and to the lt if the exponent is negative. For example, 20.13×103 is equal to 20,130 and 1.91×10-4 is equal to 0.000191.
