Multiplication and Division Flashcards
a rectangular arrangement of elements, such as squares or dots, organized in rows and columns
array
this property states that the product of a set of numbers is the same no matter how the numbers are grouped
Associative Property of Multiplication
a counting number that has more than two unique facts. More than one rectangular array can be drawn to represent each kind of this number.
composite number
sets that have no members in common.Even and Odd numbers are an example
disjoint sets
this property states that multiplying a number times the sum of two numbers gives the same result as multiplying a number times the first of two numbers then adding that to the product of the number and the second of two numbers. Written:
a * (b+c) =(ab)+(ac)
distributive property of multiplication over addition
this property states that multiplying a number times the difference of two numbers gives the same result as multiplying a number times the first of two numbers then subtracting that from the product of the number and the second of two numbers. Written:
a * (b-c) =(ab)-(ac)
distributive property of multiplication over subtraction
the quantity in a division problem that is being divided
dividend
the quantity in a division problem by which another quantity is to be divided
divisor
a number divisible by two. Numbers with 0,2,4,6, or 8 in the ones place.
even numbers
a number that divides exactly into a given whole number
factor
the greatest counting number that is a common factor of two or more numbers
greatest common factor
a number (1) that can be multiplied by any other number, which results in a product that is the other number
identity for multiplication
the set of members that two or more sets have in common
intersection
the least number that is a common multiple of two or more numbers
least common multiple
a number that is a product of a given number and a whole number
multiple
a number that is not divisible by 2. Numbers with a 1,3,5,7, or 9 in the ones place are examples
odd number
a counting number that has exactly two unique factors, 1 and the number itself
prime number
the answer to a multiplication problem
product
the answer to a division problem
quotient
the quantity that is left over when the quotient is not a whole number result
remainder
a number that is equal to a counting number times itself
square number
a pictorial method of representing relationships between sets, where the circular area represent groups of items with common properties.
