Definitions Identifying Parts of Expressions
Algebraic Expression • Can have variables, numbers, addition, subtraction, multiplication, division, parenthesis, square roots, exponents… • Examples:
Variable • Symbols or letters used to represent an unknown • Examples:
Term • How many items are being added, subtracted, divided • Examples: 3 terms 4 terms
Like Terms • Same variable raised to the same power • Examples:
Coefficient • The number multiplying to a variable (in front) • Examples: 123 9 1
Exponent • The number in the superscript of a base • The number of times you multiply something to itself • Examples: 3 1 4
Base • What the exponent sits on • The part that has been raised to a power • Examples: 2 x y
Constant • A number that has no variable • It can be positive or negative • Examples: -42 5 -8
Factors • Items that are being multiplied together • Can be numbers, variables, parenthesis • Examples: 1 and 6…. Or 2 and 3 9 and x and y (x + 2) and (y – 3) 3 and (z – 9)
Sum • The answer to an addition problem Examples 3 + 5 7(4) + 1 6 – 3 + 9
Difference • The answer to a subtraction problem Examples 10 - 4 8 – 3(2) 7 + 3 - 1
Product • The answer to a multiplication problem Examples 8(4) 6÷ 3(4) 7(4+2)
Quotient • The answer to a division problem Examples 9÷ 3 7(4)÷ 2 (8+2)÷ 5
Example 1: Given the following expression, determine the number of terms, the constants and the coefficients. 3 x 2 + 4 x – 3
Quick Check! • You try!
Example 2: Simplify the expression and then identify the number of terms, the constants and the coefficients 2(x + 3) – 4(x + 2)
Quick Check! • You try!
Example 3: Identify the factors of the expression. 3(x+3)x 2
TRANSLATING EXPRESSIONS
Fill in the words!
Example 1: Translate the words into an algebraic expression The sum of 2 times a number and 4.
Quick Check! 1. The sum of a number and 10 2. The product of 8 and x squared. 3. 9 less than g to the fourth power.
Example 2: Create an algebraic expression for the situation. John is three times as heavy as Amy.
