Middle Grade Math And Basic Algebra

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






2. Math phrase that uses variables - numbers and operation symbols






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






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






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






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






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






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






9. 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






10. A real number that cannot be expressed as a rational number






11. Letter that represents a number; variable amounts may change






12. Statement that two fractions or ratios are equal






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






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






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






16. 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






17. The distance from zero to the real number on a number line.






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






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






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






21. (mathematics) one of a pair of numbers whose sum is zero






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






23. A function whose graph is a straight line.






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






25. Expressions that contain the same variables to the same power






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






27. The reciprocal of a number.






28. 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.






29. Same shape - but different size






30. Numeric value that does not change






31. 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






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






33. 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






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






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






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






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






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






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






40. 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






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






43. 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)






44. Numeric value that does not change






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






46. A real number that cannot be expressed as a rational number






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






48. 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.






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






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