factor |
a number that is multiplied by another number to find a product Example: What are the factors of 12?3 and 4 are factors of 12, because 3 × 4 = 12. Also 2 × 6 = 12 so 2 and 6 are also factors of 12. And 1 × 12 = 12 so 1 and 12 are factors of 12 as well. |
|
|
product |
the answer to a multiplication problem |
|
|
array |
an arrangement of objects in rows and columns Example: 3 rows x 4 colums of x's give you 12 x's XXXX XXXX XXXX |
|
|
fact family |
a set of related multiplication and division equations, or addition and subtraction equations. Example: 7x8=56 8x7=56 56÷7=8 56÷8=7 |
|
|
estimate |
a number that is close to the exact amount |
|
|
Commutative Property |
the property that states that when the order of two addends or factors is changed the sum or product is the same Example: 4+5=5+4 4x5=5x4 |
|
|
Associative Property |
the property that states that you can group addends or factors in different ways and still get the same sum or product Example: 3+(8+5)=(3+8)+5 3x(4x2)=(3x4)x2 |
|
|
Property of One |
the product of any number and 1 is that number 8x1=8 9x1=9 7x1=7 |
|
|
Zero Property |
the product of 0 and any number is 0 5x0=0 7x0=0 5000x0=0 1,000,000,000x0=0 |
|
|
Distributive Property |
multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products Example: 5x(10+6)=(5X10)+(5x6) |
