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






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






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






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






5. 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






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






7. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






21. 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






22. 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).






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






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






25. A function whose graph is a straight line.






26. (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.






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






28. 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






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






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






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






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






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






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






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






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






37. Numeric value that does not change






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






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






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






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






42. A quantity that does not vary






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