How To Write Algebraic Expressions In Words Write an expression for the number of dimes. solution: let x be the number of quarters. thus, the number of dimes = 6 less than 7 times the number of quarters. = 6 less than 7x. = 7x – 6. the number of dimes is 7x – 6. learn to write algebraic expressions from phrases and word problems with introduction & examples. Translate each word phrase into an algebraic expression: 1. the difference of 20 20 and 4 4. 2. the quotient of 10x 10 x and 3 3. solution. 1. the key word is difference, which tells us the operation is subtraction. look for the words of and and to find the numbers to subtract.

You can convert any algebraic expression to word form or vice versa. for example, m 2m 2 can be written as “2“2 more than m”m”. 2a 92a 9 can be written as “9“9 more than twice a number a”a”. “5“5 less than h”h” can be written as h − 5h − 5. “4“4 times the sum of 88 and t”t” can be written as 4(8 t)4. This is the correct way to write the expression. based on the order of operations, always solve operations in parentheses first. here, you'd add 4 2, then multiply that sum by 5 —in other words, exactly what was written in the original expression. writing algebraic expressions can be confusing for some. use this lesson on writing algebraic.
