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






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






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 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.






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






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






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






8. Same shape - but different size






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






10. 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).






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






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






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






14. 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.






15. Statement that two fractions or ratios are equal






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






17. 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






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






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






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






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






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






23. A quantity that does not vary






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






25. (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.






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






27. 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






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






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






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






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






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






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






34. 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)






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






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






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






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






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






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






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






42. Numeric value that does not change






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






44. Statement that two fractions or ratios are equal






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






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