 MATHEMATICAl OPERATIONS Remember what each sign signifies: + means plus, or and, or added to: 2 + 3 = 5 reads: 2 plus 3 is 5, or 2 and 3 is 5, or 2 plus 3 equals 5, or 3 added to 2 is 5, or 2 plus 3 is 5.– means minus, or less, or subtracted from: 6 – 4 = 2 reads: 6 minus 4 is 2, or 6 less 4 is 2, or 4 subtracted from 6 is 2, or 6 minus 4 equals 2.x means times, or multiplied by: 2 x 3 = 6 reads: 2 times 3 is 6, or 2 multiplied by 3 is 6, or 2 times 3 equals 6.÷ means divided by, or goes into: 8 ÷ 2 = 4 reads: 8 divided by 2 is 4, or 2 goes into 8 4 times, or 8 divided by 2 equals 4. 1. Addition means to add. Add 2 and 2 and you get 4. 2 + 2 = 4 (2 PLUS 2 is 4) or (2 AND 2 is 4) 2. Subtraction means to subtract. Subtract 4 from 9 and you get 5. 9  4 = 5 (9 MINUS 4 is 5) 3. Multiplication means to multiply. Multiply 3 by 4 and you get 12. 4 X 3 = 12 (4 TIMES 3 is 12) 4. Division means to divide. Divide 18 by 6 and you get 3. 18 ÷ 6 = 3 (18 DIVIDED BY 6 is 3) 5. = is the equals sign (say is or are or equal or equals) + is the plus sign (say plus or and)  or – is the minus sign (say minus, or subtracted from: 4 subtracted from 9 is 5) X or x is the times sign (say times, or multiplied by: 3 multiplied by 4 is 12) ÷ is the division sign (say divided by,or goes into: 6 goes into 18 three times) . is the decimal point or decimal or point (say point: 3.7 = 3 POINT 7, NOT 3 decimal point 7, NOT 3 decimal 7) 6. Fractions (e.g., 1/5) and Decimals (e.g., 0.2) 1/5 = onefifth = .2 = twotenths 1/4 = onefourth = .25 = 25 hundredths 1/3 = onethird = .33 = 33 hundredths 1/2 = onehalf = .5 = fivetenths 2/3 = twothirds 3/4 = threefourths 1 1/2 = one and a half OR one and onehalf = 1.5 = one point fiveTOPIC : Mathematical Operations SOURCE : Linguistic Studies ** http://languages.forumactif.org/
