Study Notes
Key Vocabulary in Pre-Algebra
-
Inverse: Refers to the opposite of a given operation or value.
-
Subtracting a Negative Number: Effectively means adding a positive number, changing the equation's outcome.
-
Integers: Include all whole numbers, both positive and negative, along with zero.
-
Positive Times or Divided by a Negative: Results in a negative value.
-
Negative Times or Divided by a Positive: Also results in a negative value.
-
Negative Times or Divided by a Negative: Yields a positive value.

Important Mathematical Concepts
-
Exponent: A small numerical symbol indicating how many times to multiply the base number by itself.
-
Exponential Notation: Utilizes powers of ten to represent place values in a more compact form.
-
Additive Inverse: A number that, when added to another, will total zero (e.g., 5 + (-5) = 0).
-
Hypotenuse: The longest side in a right triangle, opposite the right angle.
Properties of Operations
-
Commutative Property: Indicates that the order of numbers does not affect the result in addition and multiplication (e.g., a + b = b + a).
-
Associative Property: Allows for the regrouping of numbers without altering the outcome in operations (e.g., (a + b) + c = a + (b + c)).
-
Distributive Property: Describes how to multiply a single term by each term within a set of parentheses (e.g., a(b + c) = ab + ac).
-
Multiplicative Inverse: Commonly known as the reciprocal, it is the number that, when multiplied by the original number, results in one (e.g., 2 × 1/2 = 1).
