  数词加减乘除的表示法
 
  1. “加”用plus,and或add表示;“等于”用is,make,equal等词表示。
 
  2+3=? 可表示为: How much is two plus three?
 
  2+3=5
 
  Two plus three is five.
 
  Two and three is equal to five.
 
  Two and three make five.
 
  Two added to three equals five.
 
  If we add two to/and three, we get five.
 
  二加三等于五
 
  2. “减”用 minus或 take from表示
 
  10-6=? How much is ten minus six?
 
  10-6=4
 
  Ten minus six is four.
 
  Take six from ten and the remainder is four.
 
  Six (taken) from ten is four.
 
  十减去六等于四
 
  3. “乘”用time(动词)或multiply表示
 
  3X4=? How much is three times four?
 
  3X4=12
 
  Three times four is/are twelve.
 
  Multiply three by four,we get twelve.
 
  Three multiplied by four makes twelve.
 
  三乘以四等于十二
 
  4. “除”用divide的过去分词形式表示
 
  16÷4=? How much is sixteen divided by four?
 
  16÷4=4
 
  Sixteen divided by four is four.
 
  Sixteen divided by four equals/gives/makes four.
 
  十六除以四等于四。
 
  五、分数表示法
 
  1. 分数是由基数词和序数词一起来表示的。基数词作分子,序数词作分母,除了分子是“1”以外,其它情况下序数词都要用复数形式。
 
  3/4 three fourths或 three quarters
 
  1/3 one third或a third
 
  24/25 twenty-four twenty-fifths
 
  3 1/4 three and one fourth或 three and one quarter
 
  1/2 a half
 
  1/4 one quarter或a quarter
 
  1 1/2 one and a half
 
  1 1/4 one and a quarter
 
  2. 当分数后面接名词时,如果分数表示的值大于1,名词用复数;小于1,名词用单数。
 
  1 1/2 hours 一个半小时(读作 one and a half hours)
 
  2 3/4 meters 二又四分之三米(读作two and three-fourths meters)
 
  4/5 meter 五分之四米
 
  5/6 inch 六分之五英寸
 
  3. 表示“n次方”的说法:指数用序数词,底数用基数词。
 
  10的7次方 the seventh power of ten(ten to the seventh power)
 
  6的10次方 the tenth power of six(six to the tenth power)
