By now, you are already familiar with algebraic expressions. The expression x and x+3 are algebraic expressions. In expressions, w is a variable. Variables may be used to represent patterns in expressions. Suppose that in a certain rectangle, the length is 3 inches more than the width. There are possible values for the length and width as shown in the table below.
Can you see the pattern?
From the table above, the pattern that exists between the width and the length is summarized by the algebraic expressions w and w+3, respectively. That is the length, the length of the rectangle is 3 inches more than its width.
Many words and phrases suggest mathematical operations . The following common words and phrases indicate addition, subtraction, multiplication, and division.
Translating in mathematics usually involves changing a verbal phrase, or sentence, into a mathematical phrase, or sentence. In this lesson we will do the reverse. We will translate a mathematical phrase, or sentence, into a verbal phrase.
Another example of translating in mathematics usually involves changing a verbal phrase, or sentence, into a mathematical phrase, or sentence.
