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. 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






2. The reciprocal of a number.






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






4. 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).






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






6. Numeric value that does not change






7. Specific form of representing ratios - examples - a:b or 2:3






8. 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)






9. Same shape - but different size






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






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






12. An equation whose solutions form a straight line on a coordinate plane; example: y = 3x - 1






13. The number that indicates how many times the base is used as a factor






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






15. An equation whose solutions form a straight line on a coordinate plane; example: y = 3x - 1






16. Statement that two fractions or ratios are equal






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






18. The ratio of dimensions of the new image to those of the original figure






19. 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






20. 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






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






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






23. 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






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






25. 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






26. A pair of numbers that can be used to locate a point on a coordinate plane.






27. 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






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. A pair of numbers that can be used to locate a point on a coordinate plane.






30. A decimal number that ends or terminates; example: 6.75






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






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






33. A decimal number that ends or terminates; example: 6.75






34. 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






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






36. 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.






37. 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.






38. The ratio between the size of something and a representation of it






39. Fractions that name the same amount or part - 1/2 and 2/4 are equivalent fractions






40. 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






41. The x- and y-axes divide the coordinate plane into four regions. Each region is called a quadrant.






42. (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.






43. 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.






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