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. (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.






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






3. 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






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






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






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






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






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






9. 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.






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






11. Same shape - but different size






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






13. (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.






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






15. 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






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






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






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






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






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






22. Numeric value that does not change






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






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






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






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






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






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






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






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






31. Statement that two fractions or ratios are equal






32. A quantity that does not vary






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






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






35. 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






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






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






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






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






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






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