Term | Definition |
base | when a # is written in exponent form the # used as a factor is the base. 5^4=5*5*5*5 |
composite | A # with more than 2 factors. 24's factors= 1,2,3,4,6,8,12,24 |
divisible | A # that can be divided into by a second # evenly. 16 is divisible by 1,2,4,8,and 16. |
exponent | It tells how many times the base is multiplied by itself. 3^4= 3*3*3*3 |
factor | A whole number that can divide evenly into another number. 36/3=12 |
formula | It shows up in the relationship between 2 or more factors. P= 2k+2w |
greatest common factor | The greatest # the two numbers can go into evenly. 12 and 30's GCF=6 |
least common denominator | It is the smallest denominator the fractions will go into evenly. 3/8 and 7/10 would be 40 |
least common multiple | It is the smallest multiple of both #s. 15 and 6 is 30. |
multiplicative inverse | It is the reciprocal for a #. 4/9 = 9/4 |
power | A # that can be expressed by a base & expontent. 10^2= 10*10 |
prime factorization | Basically it is breaking down a composite # to its prime factors. 12= 2*2*3 |
prime number | It is a # with 2 factors, 1 and itself. 13's prime factors = 1,13 |
rational number | It is a # that can be written in fraction form. 3=3/1 |
reciprocals | It is 2 fractions whos product is 1. 4/9*9/4=1 |
relatively prime | It is a # whos GCF is 1. 1/4,9/10,2/3 |
repeating decimal | It is a decimal with no end but, its decimals repeat indefinately. .888=.8 with a line over it. |
scientific notation | It shortens a big # into powers, 10,000,000 would be 10^6 |
terminating decimal | It is a decimal the stops or completes. .6 and .555 terminate. |
