Study Notes
Algebraic Properties
- Commutative Property of Addition: Order of terms does not affect the sum; e.g., a + b = b + a.
- Commutative Property of Multiplication: Order of factors does not alter the product; e.g., ab = ba.
- Associative Property of Addition: Grouping of terms does not change the sum; e.g., (a + b) + c = a + (b + c).
- Associative Property of Multiplication: Grouping of factors does not impact the product; e.g., (ab)c = a(bc).
- Distributive Property: Multiply each term inside parentheses by the term outside; e.g., a(b + c) = ab + ac.
Algebraic Expressions
- Expression for "the total of a number a and a number b" is a + b.
- Expression for "9 increased by a number a" is 9 + a.
- Expression for "a number b plus the quotient of 8 and a number b" is b + 8/b.
- Expression for "the product of 4 and the difference of 10 and a number b" is 4(10 - b).
- Expression for "25 less than a number b" is b - 25.
- Expression for "a number x divided by 4" is x/4.
- Expression for "100 decreased by a number k" is 100 - k.
- Expression for "6 more than the product of 8 and a number x" is 8x + 6.
- Expression for "3 less than the quotient of a number y and 4" is y/4 - 3.
Components of Expressions
- Coefficient: Numerical factor in a term containing a variable, e.g., in 10c, 10 is the coefficient.
- Constant: A term without a variable, e.g., in 12 + 10c, 12 is the constant.
- Variable: Symbolic representation of one or more numbers.
Identifying Components
- In the expression 12 + 10c, the coefficient is 10 and the constant is 12.
- In the expression g + 15 + 9g, the coefficients are 1 and 9, while the constant is 15.
Special Properties of Numbers
- Addition Property of Zero: The sum of any number and 0 equals the number itself; e.g., a + 0 = a.
- Multiplication Property of Zero: The product of any number and 0 yields 0; e.g., a * 0 = 0.
- Multiplication Property of One: The product of any number and 1 equals the number; e.g., a * 1 = a.
