表達加減乘除

表達 (X) 加幾 (Y),可透過 add X and Y (together) add X to YIf you add 2 and 3, you get 5. ( 235)  Add five to six to get eleven. ( 5611) 另外,表達 (X) 加幾 (Y),也可透過 X plus Y ( plus 在此作介系詞用 )Two plus three is five. ( 23等於5)  4 plus 5 equals 9. ( 45等於9)
還有,表達 幾個數字相加的總和是多少 (Z) 或等於多少 (Z),可透過 be Zadd up to Zequal Z ( equal 作動詞 )be equal to Z ( equal 作形容詞 )make Z 等:2 and 6 is 8. 2 and 6 are 8. ( 26等於8)  The four angles of a parallelogram always add up to 360 degrees. ( 平行四邊形的四角總和永遠為360度。)  4x plus 2y equals 100. ( 4x2y等於100)  2 imperial pints or 40 imperial fluid ounces are equal to 1 imperial quart. ( 2英制品脫或40英制液盎司等於1英制夸脫。)  3 and 5 make(s) 8. ( 35等於8)  One hundred pence (= pennies) make(s) a pound. ( 100便士等於1英鎊。) 表達 (X) 減幾 (Y),可透過 subtract Y from Xtake Y (away) from X X take away YIf you subtract 5 from 11, you get 6. ( 1156)  3 subtracted from 12 equals 9. ( 123等於9)  Take 2 (away) from 6 and the remainder is 4. ( 624)  Eight take away two is six. ( 82等於6) 另外,表達 (X) 減幾 (Y),也可透過 X minus Y Y from X ( minus from 在此都作介系詞用 )10 minus 2 leaves 8. ( 1028)  Eight from twelve is four. ( 128等於4) 表達 (X) 乘幾 (Y),可透過 multiply X by Y multiply X and Y (together)Multiply 4 by 2 to get 8. ( 428)  Three multiplied by five equals fifteen. ( 35等於15)  Multiply the length and width (together) to calculate the area. ( 長寬相乘以計算面積。) 另外,表達 (X) 乘幾 (Y),也可透過也可透過 X times Y ( times 在此作介系詞用 ) X Ys4 times 3 is 12. ( 43等於12)  Two threes are six. ( 23等於6) 表達 (X) 除以幾 (Y),可透過 divide X by YIf you divide thirty by ten, you get three. ( 30除以103)  4 divided by 2 is 2. ( 4除以2等於2)  16 can be divided by 4. ( 16 可以被4整除。) 另外,表達 某個較大的數 (X) 可以被某個較小的數 (Y) 整除幾次 (Z),可透過 Y divides into X Z timesY goes into X Z times Y(s) into X goes Z (times)20 divides into 80 four times. ( 80可被20 整除4次。)  How many times will five go into sixty? ( 60可以被 5 整除幾次?)  Four(s) into twelve goes three (times). ( 12可以被 4 整除3次。)
