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 ratio between the size of something and a representation of it






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






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






5. A quantity that does not vary






6. 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






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






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






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






10. 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






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






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






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






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






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






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






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






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






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






20. 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






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






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






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






24. Statement that two fractions or ratios are equal






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






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






28. A function whose graph is a straight line.






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






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






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






32. 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






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






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






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






36. 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).






37. Statement that two fractions or ratios are equal






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






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






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






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






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






43. 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.






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