Question | Answer |
---|---|
Associative Property | for addition and multiplication, three numbers can be grouped in any order; the sum or product will be the same; for any numbers a, b, and c, (a+b)+c equals a+(b+c); (ab)c equals a(bc) |
Base | one of the factors in a power (for example, in 3 to the power of 2 the base is 3 and the exponent is 2) |
Communtative Property | for addition and multiplication, numbers can be added or multiplied in any order; the sum or product will be the same; for any numbers a and b, a+b equals b+a and ab equals ba |
Compatible Pairs | numbers that divide evenly (for example, 80 and 4800) |
Consecutive Numbers | one number following the other (for example, 19 and 20) |
Difference | the answer to a subtraction problem |
Digit | one of the ten number symbols (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) |
Distributive Property | when multiplying a number by a sum or difference, you may first multiply each number in the sum or difference, or you can first find the sum or difference and then multiply: a(b+c) = ab+ac; and a(b-c) = ab-ac |
Dividend | the number that is divided in a division problem |
Divisor | the number that goes into another number in a division problem |
Estimate | an approximate value or to find an approximate value |
Even Number | a whole number that is evenly divisible by 2 |
Exponent | a number that tells the power to which a base is raised (in 3 to the power of 2 the base is three and the exponent is 2) |
Factor | a number that divides evenly into another number |
Grouping Symbols | symbols such as parentheses or the fraction bar that tell which operations to do first |
Mean | another name for average; the sum of a set of numbers divided by the number of numbers in the group |
Median | a number in the middle of a set of numbers; or the average of two middle numbers in a set |
Number Sequence | a list of numbers in a special order or pattern (for example, 2, 4, 6, 8, 10...). Also called a number series. |
Odd Number | a whole number that is not evenly distributed by 2 |
Place Value | the number that a digit stands for (for example, in 35.6, the digit 3 stands for 30 and the digit 6 stands for 6/10ths) |
Positive Number | a number greater than zero |
Power | a product of identical factors (for example, 3 to the second power means 3x3) |
Prime Number | a number that is evenly divisible only by itself and 1 |
Product | the answer to a multiplication problem |
Quotient | the answer to a division problem |
Square Root | one of two equal factors of a number, the symbol is a checkmark |
Round Number | a number that ends in a zero or zeros |
Rounding | making an estimate that is close to the original amount; can round up or down |
Square | a number raised to the second power |
Sum | the answer to an addition problem |
Whole Number | a number that is evenly divisible by 1 (not a fraction or a decimal) |
