Subjects : math, algebra
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Math phrase that uses variables - numbers and operation symbols






2. A number multiplied by a variable in an algebraic expression; a constant number that serves as a measure of some property or characteristic






3. The plane formed by 2 number lines that intersect at their zero points dividing the plane into 4 quadrants; A coordinate system formed by the intersection of a horizontal number line - called the x-axis - and a vertical number line - called the y-axi






4. A property indicating a special way in Which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses - such as a(b + c) = ab + ac; ex: 4(3 + 8)






5. An input-output relationship that has exactly one output for each input; An equation written with two variables where only one output exists for each input; example: y = 2x +1






6. All rational or irrational numbers; real numbers can be represented on the real number line






7. The order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction






8. A quantity obtained by multiplication; the answer to a multiplication problem






9. Changing the grouping of terms will not change the sum - (a + b) + c = a + (b + c); ex: (5+3) + 1 = 5 + (3 + 1)






10. The operation which undoes an operation - the opposite operation: subtraction is the inverse of addition - addition is the inverse of subtraction; division is the inverse of multiplication - multiplication is the inverse of division - square root is






11. A number written as the product of its prime factors; examples: 10 = 2 5 - 24 = 2^3 3 (^3 means the 3 is written smaller and to the upper right of 2).






12. The reciprocal of a number.






13. Specific form of representing ratios - examples - a/b or 2/3 (denominator cannot be zero)






14. A symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity; in the expression 2x + 3 - x is the variable






15. A function whose graph is a straight line.






16. Any of the natural numbers (positive or negative) or zero; any of the set of whole numbers and their opposites






17. States that changing grouping of factors does not change the product. (ab)c = a(bc); ex: (2 6) 7 = 2 (6 7)






18. The Zero Property of Addition. Adding 0 to a number leaves it unchanged; ex: 67+0=67 - 67+0=67






19. Any of the numbers (or symbols) that form a product when multiplied together; 3 is a factor of 9






20. Any of the numbers (or symbols) that form a product when multiplied together; 3 is a factor of 9






21. For any number a and b - a + b = b + a






22. The operation which undoes an operation - the opposite operation: subtraction is the inverse of addition - addition is the inverse of subtraction; division is the inverse of multiplication - multiplication is the inverse of division - square root is






23. A number that can be written as a/b where a and b are integers - but b is not equal to 0; an integer or a fraction; examples: 6 can be expressed as 6/1; 0.5 can be expressed as 1/2.






24. A method of measurement that uses formulas - similar figures - and/or proportions.






25. A comparison of two quantities - may be directly represented by numbers and or variables






26. An expression that contains only numbers and operations (2 3) + 1






27. An ordered list or numbers; example: 2 -4 -6 -8 -10...






28. A property indicating a special way in Which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses - such as a(b + c) = ab + ac; ex: 4(3 + 8)






29. The smallest number - other than zero - that is a multiple of two or more given numbers; The LCM of 10 and 18 is 90.






30. The number obtained by division; the ratio of two quantities to be divided; the answer to a division problem






31. A method of measurement that uses formulas - similar figures - and/or proportions.






32. A fraction in which the numerator is greater than or equal to the denominator; examples: 5/5 or 7/4






33. (mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; a fraction that has been flipped. The reciprocal of 3/4 is 4/3.






34. A diagram of an object in which the dimensions are in proportion to the actual dimensions of the object.






35. A number written as the product of its prime factors; examples: 10 = 2 5 - 24 = 2^3 3 (^3 means the 3 is written smaller and to the upper right of 2).






36. The product of a quantity by an integer; example 24 is a multiple of 3 and 8






37. A mathematical phrase involving one or more terms and operations






38. Statement that two fractions or ratios are equal






39. The point where the x-axis and y-axis intersect on the coordinate plane; (0 - 0).






40. Changing the order of the factors does not change the product; for example 10 x 9 = 9 x 10; a b = b a






41. The largest common factor of two or more given numbers; The GCF of 27 and 45 is 9.






42. A decimal in which one or more digits repeat infinitely; The repeating portion of the decimal is shown with a short line drawn over the repeating numbers.

44. The smallest number - other than zero - that is a multiple of two or more given numbers; The LCM of 10 and 18 is 90.






45. The Zero Property of Addition. Adding 0 to a number leaves it unchanged; ex: 67+0=67 - 67+0=67
