Writing expression basic

Expressions Some expression 11 = (1 x 10) + 1, 12 = (1 x 10) + 2 In the above numerical expressions we have used only numbers 1, 2, 3 ... To form numerical expressions we use addition, subtraction, multiplication and division signs.

Algebraic expression An algebraic expression is a combination of variables and constants connected by arithmetic operations. Example m + 8 r – 3

x+4 t + 8 Phrase Expression 4 more than number x Writing algebraic expression that involves addition Phrase Expression 4 more than number x x+4 number y increased by 10 y + 10 8 plus number t t + 8 the sum of a number w and 12 w + 12

8 - t X - 4 y -10 8 minus number t W -12 Phrase Expression Writing algebraic expression that involves subtraction Phrase Expression 4 less than number x X - 4 Number y decreased by 10 y -10 8 - t 8 minus number t the difference between 12 and number w W -12

4x 2y t 12w Writing algebraic expression that involves multiplication Phrase Expression 4 times some number x 4x 2y twice a number y t One - third of number t the product of a number W and 12 12w

x y t w Writing algebraic expression that involves division Phrase Expression the quotient of 4 and some number x x y a number y Divided by 2 the ratio of 8 and some number t t w the quotient of a number w and 12

Try these 10 multiplied by m The quotient of a number x and 10 7 more than number y
