加減乘除的運算用英語怎麼表達?常用的數學符号有哪些?
英語中加法運算、減法運算、乘法運算、除法運算的單詞分别為:
addition, subtraction, multiplication, division。
運算過程英語表達中,一般“加”用and或者plus;“減”用minus;“乘”用times或者 multiplied by;“除”用into或者divided by;
“等于”英語用be或者make或者equal表示;
注意:表示加法和乘法的算式中,謂語動詞可用單數形式和複數形式;在減法和除法的算式中,隻用單數形式。常用單數。舉例如下:
加法 5 9 = 14
讀作Five plus nine is/makes/equals fourteen.(謂語動詞單數)
或者Five plus nine are/make/equal fourteen.(謂語動詞複數)
減法16 - 7 = 9
讀作Sixteen minus seven is/makes/equals nine.(謂語動詞單數)
乘法6 x 8 = 48
讀作Six times eight is/makes/equals forty-eight.(謂語動詞單數)
或者Six times eight are/make/equal forty-eight.(謂語動詞複數)
或者Six multiplied by eight is/makes/equals forty-eight.(謂語動詞單數)
或者Six multiplied by eight are/make/equal forty-eight.(謂語動詞複數)
除法50 ÷ 5 = 10
讀作Fifty into five is/makes/equals ten.(謂語動詞單數)
或者Fifty divided by five is/makes/equals ten.(謂語動詞單數)
特殊數學符号英語表達方式如下:
“小于或等于”英語表達為 is less than or equal to,
例如:5 ≤ 6 讀作 five is less than or equal to six;
“大于或等于”英語表達為 is greater than or equal to;
例如:8 ≥ 7 讀作 eight is greater than or equal to seven;
“不大于” 用英語表達為 is not greater than;
例如:10 ≯ 11 讀作 ten is not greater than eleven;
“不小于” 英語表達為 is not less than;
例如:12 ≮ 11 讀作 twelve is not less than eleven;
“小于” 英語表達為 is less than;
例如:5 < 6 讀作 five is less than six;
“大于” 英語表達為 is greater than;
例如:7 > 6 讀作 seven is greater than six;
“約等于” 英語表達為 is approximately equal to;
例如:7.2 ≈ 7 讀作 seven point two is approximately equal to seven.
