Math Translating Algebraic Expressions By: Darala Hartwell Remember: 1. A variable is a letter used to represent an unknown value. 2. A numerical expression includes numbers and operations. 3. An algebraic expression contains variables, numbers and operations. What do I represent? What am I? How did I get here? a b x I am so unknown y Variables are letters that represent unknown values. Numerical Expressions Numerical expressions include numbers and operation symbols. Algebraic Expressions An algebraic expression includes: Numbers Operations and Variables Let’s look at examples of a numerical expressions: 12 + 3 32 8 7(4) Let’s look at examples of algebraic expressions. x-4 2(5+n) b 2 Equations Algebraic expressions like phrases in English are incomplete. An equation, like a sentence, is complete. You will notice the inclusion of a very special symbol. An equation is made up of numbers, variables, and an equal sign. 3b + 5 = 26 Rewrite these verbal expressions as algebraic expressions. 1. the sum of s and 12 s+12 2. the product of 15 and some number 15n 3. n to the seventh power n7 4. 56 increased by twice a number 56+2a 5. Four less than a number n-4 Let’s write equations for these sentences. 1. Forty-three less than n is equal to 35. n – 43 = 35 2. Seven more than y is 13. y + 7 = 13 The End
