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






2. 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






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






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






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






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






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






8. 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.






9. Statement that two fractions or ratios are equal






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






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






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






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






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






15. A function whose graph is a straight line.






16. A quantity that does not vary






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






18. 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.






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






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






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






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. 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)






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






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






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






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






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






29. 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).






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






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






32. The reciprocal of a number.






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






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






35. (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.






36. 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






37. Numeric value that does not change






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






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






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






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






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






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






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






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






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






47. Statement that two fractions or ratios are equal






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






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






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