chapter 2

base when a number is written in exponential form, the number that is used as a factor is the base. 5^2 5=base
composite number a number greater than 1 that has more than two factors 4 = composite number
equivalent fractions equivalent fractions are fractions that name the same amount 1/2 and 2/4 are equivalent fractions
factor a whole number that divides another hole number with a remainder of zero 1,2,3,4,6,12,18,and 36 are all factors of 36
greatest common factor (GCF) the greatest common factor is the greatest factor that two numbers share the GCF of 12 and 30 is 6
improper fraction the numerator is larger than the denominator 45/3 is an example of an improper fraction
exponent an exponent is how many time a base is multiplied by it self 5^2 2 = exponent
least common multiple (LCM) the least multiple between two numbers the LCM of 10 and 20 is 20
mixed number a mixed number is the sum of a whole number and a fraction 3 1/2 is a mixed number
multiple a number that is the product of that number and any nonzero number 39 is a multiple of 13
power a number that can be expressed using an exponent 3^4, 5^2, and 2^10 are powers
prime factorization In number theory, integer factorization or prime factorization is the decomposition of a composite number into smaller non-trivial divisors, which when multiplied together equal the original integer the prime factorization of 12 is 2x2x3 or 2^2x3
prime number a number that is only divisible by two numbers 1 and itself 1 and 13 are examples of prime numbers
rational number a number that can be written as a quotient of two integers, where the divisor 1/3, -5, 6.4, 0.666..., -24/5, 0, and 7/3 are rational numbers
repeating decimal a decimal that repeats with out end 0.888... is a repeating decimal
scientific notation a number that is written as the product of two factors 37,000,000 is written as 3.7x10^7 in scientific notation
simplest form a fraction is in simplest form when the numerator and denominator have no common factors other than one the simplest form of 3/9 is 1/3
terminating decimal a decimal that stops or terminates both 0.6 ad 0.7265 are terminating decimals
least common denominator (LCD) the smallest whole number that is divisible by each of the denominators the LCD of the fractions 3/8 and 7/10 is 40
