Part 1
Key Terms
- absolute value
- The absolute value of a number is its distance from on the number line.
- additive identity
- The number 0 is the additive identity because adding 0 to any number does not change its value.
- additive inverse
- The opposite of a number is its additive inverse.
- coefficient
- The coefficient of a term is the constant that multiplies the variable in a term.
- complex fraction
- A fraction in which the numerator or the denominator is a fraction is called a complex fraction.
- composite number
- A composite number is a counting number that is not prime. It has factors other than 1 and the number itself.
- constant
- A constant is a number whose value always stays the same.
- denominator
- In a fraction, written where the denominator b is the number of equal parts the whole has been divided into.
- divisible by a number
- If a number m is a multiple of n, then m is divisible by n.
- equation
- An equation is two expressions connected by an equal sign.
- equivalent fractions
- Equivalent fractions are fractions that have the same value.
- evaluate an expression
- To evaluate an expression means to find the value of the expression when the variables are replaced by given numbers.
- expression
- An expression is a number, a variable, or a combination of numbers and variables using operation symbols.
- factors
- If then a and b are factors of m.
- fraction
- A fraction is written where and a is the numerator and b is the denominator. A fraction represents parts of a whole.
- integers
- The whole numbers and their opposites are called the integers.
- irrational number
- An irrational number is a number that cannot be written as the ratio of two integers. Its decimal form does not stop and does not repeat.
- least common denominator
- The least common denominator (LCD) of two fractions is the least common multiple (LCM) of their denominators.
- least common multiple
- The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers.
- like terms
- Terms that are either constants or have the same variables raised to the same powers are called like terms.
- multiple of a number
- A number is a multiple of n if it is the product of a counting number and n.
- multiplicative identity
- The number 1 is the multiplicative identity because multiplying 1 by any number does not change its value.
- multiplicative inverse
- The reciprocal of a number is its multiplicative inverse.
- negative numbers
- Numbers less than are negative numbers.
- numerator
- In a fraction, written where the numerator a indicates how many parts are included.
- opposite
- The opposite of a number is the number that is the same distance from zero on the number line but on the opposite side of zero.
- order of operations
- The order of operations are established guidelines for simplifying an expression.
- percent
- A percent is a ratio whose denominator is 100.
- prime factorization
- The prime factorization of a number is the product of prime numbers that equals the number.
- prime number
- A prime number is a counting number greater than 1 whose only factors are 1 and the number itself.
- principal square root
- The positive square root is called the principal square root.
- rational number
- A rational number is a number of the form where p and q are integers and Its decimal form stops or repeats.
- real number
- A real number is a number that is either rational or irrational.
- reciprocal
- The reciprocal of a fraction is found by inverting the fraction, placing the numerator in the denominator and the denominator in the numerator.
- simplify an expression
- To simplify an expression means to do all the math possible.
- square of a number
- If then m is the square of n.
- square root of a number
- If then n is a square root of m.
- term
- A term is a constant, or the product of a constant and one or more variables.
