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. Same shape - but different size






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






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






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






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






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






7. (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.






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






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






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






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






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






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






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






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






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






17. Numeric value that does not change






18. The reciprocal of a number.






19. 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






20. 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).






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






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






23. Same shape - but different size






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






25. 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






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






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






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






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






30. 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)






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






32. An input-output relationship that has exactly one output for each input; An equation written with two variables where only one output exists for each input; example: y = 2x +1






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






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






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






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






37. 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






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






39. 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






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






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






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






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