To combine, put together two or more quantities
Any number being added
associative property of multiplication
The product stays the same when the grouping of addends is changed. (a x b) x c = a x (b x c), where a, b, and c stand for any real numbers.
A step by step method of computing
associative property of addition
The sum stays the same when the grouping of addends is changed. (a + b) + c = a + (b + c), where a, b, and c stand for any real numbers.
Any common multiple of two or more numbers
commutative property of multiplication
The product stays the same when the order of the factors is changed. a x b = b x a, where a and b are real numbers.
To decide if one number is greater than, less than or equal to another number.
commutative property of addition
The sum stays the same when the order of the addends is changed. a + b = b + a, where a and b are any real numbers.
To put together components or basic elements.
The amount that remains after one quantity is subtracted from another.
A quantity to be divided.
Any of the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9.
To separate into components or basic elements.
To separate into equal groups and find the number in each group or the number of groups.
When one of the factors of a product is a sum, multiplying each addend before adding does not change the product.
The quantity by which another quantity is to be divided.
Having the same value.
Groups that contain the same number of objects. Whenever you divide, you separate items into these.
To find a number close to an exact amount, this tells about how much or about how many.

A way to write numbers that shows the place value of each digit.
A number greater than 0 that has more than two different factors.
A set of two whole numbers when multiplied, will result in a given product.
A rule that is written as an equation
Greater than is used to compare two numbers when the first number is larger than the second number.
least common multiple
LCM. The smallest common multiple of a set of two or more numbers.
Less than is used to compare two numbers when the first number is smaller than the second number.
identity property of multiplication
If you multiply a number by one, the product is the same as that number.
is not equal to
is not that same as.
The product of a whole number and any other whole number.
identity property of addition
If you add zero to a number, the sum is the same as that number.

Length is measured in units such as inches, feet, centimeters, etc.
order of operations
A set of rules that tells the order in which to compute.
