How to Write Variable Expressions in Words

Variable expressions use variables, operators, and constants to convey a mathematical relationship.

Young children often question why they must learn about subjects such as mathematics. A way to make math more interesting is to allow students to take variable expressions and change them into words. Variable expressions are composed of variables, operators and constants that convey a mathematical relationship. For example, the variable expression "2a + 3" would read "the sum of twice the number of apples and three" if 'a' represented the number of apples. This method allows students to better relate to the subject material.

Instructions

1. Take the variable expression and split each part into separate components. Each variable, operator and constant should be isolated. This allows for the translator to look at each piece of the expression one at a time.

2. Convert each part of the variable expression into a word. For example, a "+" sign becomes "sum," a "-" becomes "difference," an "x" becomes "product," a "/" becomes "quotient," and a "^2" becomes "squared." The variables are already in word form and cannot be translated.

3. Put the words back together to form a verbal expression. Ensure that the order of the words is correct. For example, a verbal expression should read "the product of a and b" rather than "a product b."
