Place value
|
Place value is the value of a digit depending on its place in a number.
|
|
|
Exponents
|
Exponents are shorthand for multiplication. You can write 2•2•2 as 2^3. 2 is the base and 3 is the exponent.
|
|
|
Standard form
|
A number written in standard form is 88,000.
|
|
|
Scientific notation
|
Scientific notation is a way of writing large (or small) numbers. 88,000 is 8.8 x 10^4.
|
Scientific notation consists of a number greater than or equal to 1 and less than 10, x (multiplication sign), and a power of 10. To write a number in scientific notation, count how many places you must move the decimal point to get a number greater than or equal to 1 and less than 10. The number of places you move the decimal point is the power of 10.
|
|
Factors
|
Factors are the numbers you multiply to get another number.
|
|
|
Divisible
|
The number is divisible by the factor. For instance, the factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.
|
|
|
Prime number
|
A number that can only be factored as 1 times itself is called prime. The first few primes are 2, 3, 5, 7, 11, and 13. The number 1 is not regarded as a prime, and is usually not included in factorizations, because 1 goes in to everything.
|
|
|
Composite number
|
A composite number has more than two factors.
|
|
|
Prime factorization
|
The prime factorization of a number is the list of all the prime
|
|
|
Greatest Common Factor (GCF)
|
The greatest common factor (GCF) is the greatest number that is a factor of both of them.
|
|
|
Least Common Multiples (LCM)
|
The least common multiple (LCM) is the smallest number that is a common multiple of the given numbers.Note: The LCM is the largest number or a multiple of it.
|
|
|
Fraction
|
The symbol represents a fraction where n and d are whole numbers and d is not 0.
|
|
|
Numerator
|
The top number n is the numerator.
|
|
|
Denominator
|
and the bottom number b is the denominator.
|
|
|
Equivalent
|
If fractions represent the same quantity, they are equivalent.
|
|
|
Lowest terms
|
To write a fraction in lowest terms, divide both the numerator and the denominator by the greatest common factor of each number.
|
|
|
Common denominator
|
Fractions with the same denominator are said to have a common denominator.
|
|
|
1/3
|
means “one divided by 3” or “one part out of three parts”.
|
|
|
Fractions and decimals
|
Fractions and decimals are different ways of writing the same quantity.
|
|
|
Terminating decimal
|
A terminating decimal ends. (3/5)
|
|
|
Repeating decimal
|
A repeating decimal repeats a pattern of digits. (5/9)
