| A | B |
|---|
| exponent | a number that tells how many times a factor is used |
| factor | a number multiplied with another number to get a product |
| product | the answer to a multiplication problem |
| sum | the answer to an addition problem |
| quotient | the answer to a division probleml |
| difference | the answer to a subtraction problem |
| prime number | a number with factors of 1 and itself |
| composite number | a number with more factors than 1 and itself |
| proper factors | factors of a number excluding the number itself |
| abundant number | a number whose proper factors add up to more than the number |
| deficient number | a number whose proper factors add up to less than the number |
| perfect number | a number whose proper factors add up to exactly the number |
| even number | a number that can be divided by 2 with no remainder |
| odd number | a number that has a remainder when divided by 2 |
| divisiblility rule for 6 | even number and sum of digits is divisible by 3 |
| divisibility rule for 5 | number ends in 0 or 5 |
| divisibility rule for 4 | last two digits are divisible by 4 |
| divisibility rule for 10 | number ends in 0 |
| divisibility rule for 9 | sum of digits is divisible by 9 |
| divisibility rule for 3 | sum of digits is divisible by 3 |
| common factors | factors that two or more numbers share |
| common multiples | multiples that two or more numbers share |
| order of operations | grouping, exponent, multiplication/division, addition/subtraction |
| conjecture | a prediction |
| relatively prime number | numbers with no common factors except 1 |
| prime factorization | the longest factor string for a number composed entirely of prime numbers |
| near perfect number | a number with proper factors that add to 1 less than the number- ex. 32 is a near perfect number because its proper factors add up to 31 |
| dimensions | the dimensions of a rectangle are its length and width |
| benchmark | A "nice" number that can be used to estimate the size of other numbers. For work with fractions, O, 1/2, and 1 are good benchmarks. |
| numerator | The number written above the line in a fraction. In the fraction 5/8, 5 is the numerator which means 5 parts out of 8. |
| denominator | The number written below the line in a fraction. In the fraction 3/4, 4 is the denominator which means that something has been divided into 4 equal-sized parts. |
| equivalent fractions | Fractions that are equal in value but have different numerators and denominators. For example, 2/3 and 14/21 are equivalent fractions. |
| mode | The category or numerical value that appears most often |
| median | The numerical value that marks the middle of a set of data |
| mean | The average |
| line plot | A simple way to organize data along a number line where x's or other symbols above the number indicate frequency |
| stem and leaf plot | A quick way to picture the shape of a distribution while including the actual numerical values in the the graph. The leaves indicate the ones digits |
| range | The distribution of a distribution is computed by subtracting the lowest value from the highest value |
| numerical data | Values that are nuumbers such as counts, measurements, and ratings |
| categorical data | Values that are words |
| y-axis | The vertical line on a coordinate graph |
| x-axis | The horizontal line on a coordinate graph |
