Numbers and Operations

TermDefinition
Natural numbers counting numbers (1, 2, 3,4...)
Whole numbers natural numbers and zero (0, 1, 2, 3...)
Integers whole numbers an their opposites (...1, 0, -1...)
Negative numbers numbers less than zero (...-3, -2, -1...)
Opposite numbers that have the same distance from 0 on a number line, but on the opposite side of 0. (-7 and 7 are opposites
rational numbers any number that can be expressed as a fraction.
absolute value a numbers distance from 0 on the number line.
Multiplication repeated addition of a number a given number of times.
product the result of multiplying two more numbers.
factors the numbers that you multiply
division separating one number into a given number of equal parts.
quotient the answer to a division problem.
dividend the number thats being divided.
divisor the number you divide by
remainder the amount left over.
divisible when a number can be divided evenly into another number with no remainder
multiples the products that result from multiplying the number by each of the whole numbers
least common multiples (LCM) the smallest multiple two or more numbers have in common.
greatest common factor (GCF) the largest common factor of two or more numbers
commutative property shows that the order of the numbers does not change the sum of an addition problem or the product of a multiplication problem. Ex: a + b = b + a a * b = b * a
associative property shows that the grouping of the numbers does not change the sum or product. Ex: (a + b) + c = a + (b + c) (a * b) * c = a * (b * c)
distributive property uses both addition and multiplication. Ex: a(b + c) = a(b) + a(c)
identity property shows the sum of any number and zero is that number and the product of any number and one is that number. Ex: a + 0 = 0 a * 1 = a
inverse property shows that the sum of a number and its opposite is zero an the product of a number and its reciprocal is one. Ex: a + (-a) = 0 a * 1/a = 1
reciprocal switching the numerator and denominator of a fraction. Ex: 1/2 & 2/1
zero property shows that the product of any number and zero is zero. Ex: 5 * 0 = 0
