Lesson 1-1. The Language of Algebra. The language of Algebra uses come and changeable stars. A variant is a symbol that displace be replaced by some(prenominal) menber of a set of numbers or separate objects. When numbers and variables be combibed using the operations of arithmetic, the result is called an algebraical expression, or simply an expression. The expression ? r ^ 2 uses the variable r and the numbers ? and 2. An algebraic expression with two variables is a + b. An algebraic sentence consists of expressions related with a verb. The most familiar verbs in algebra are = ( is constitute to ), < ( is little than ), > ( is greater than ), ? ( is less than or equal to ), ? ( is greater that or equal to ), ? ( is not equal to ), and ? ( is approximately equal to ). Some algebraic sentences are A = ? r ^ 2, a + b = b + a, and 3x + 9 < 22. Algebra is the speculate of expressions , sentences, and other relations involving variables.

Because many expressions and sentences are found on patterns in arithmetic, algebra sometimes is called generalized arithmetic. Writing Expressions and Sentences From your early memorize of algebra, you should know how to write expressions and sentences describing real situations, an! d how to evaluate expressions or sentences. fount 1 Express the cost of y groundworks of orangish juice at x cents per can. Solution 1 determination a special case. 5 cans at 60¢ per can would cost 5 * 60¢ = $3.00. That suggests multiplication. So y cans at x cents per can lead cost xy cents. Solution 2 Recognize a general stumper for multiplication. The unit cents per can, which can be written as...If you want to cut a salutary essay, order it on our website: OrderCustomPaper.com
