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






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






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






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






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






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






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






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






9. 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






10. Same shape - but different size






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






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






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






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






15. 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.






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






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






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






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






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






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






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






23. Numeric value that does not change






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






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






26. 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).






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






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






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






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






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






32. 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.






33. 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)






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






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






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. The reciprocal of a number.






38. Same shape - but different size






39. The reciprocal of a number.






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

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






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