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 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






2. 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).






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






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






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






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






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






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






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






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






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






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






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






14. 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).






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






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






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






18. 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






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






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






21. 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.






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






23. Same shape - but different size






24. A quantity that does not vary






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






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






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






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






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






30. The reciprocal of a number.






31. Statement that two fractions or ratios are equal






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






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






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






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






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






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






38. 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






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






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






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






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