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. Statement that two fractions or ratios are equal






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






3. Numeric value that does not change






4. 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






5. The reciprocal of a number.






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






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






8. 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






9. 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.






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






11. 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.

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






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






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






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






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






18. 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).






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






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. 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).






22. 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)






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






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






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






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






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






28. A quantity that does not vary






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 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






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

34. 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






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






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






37. (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.






38. Numeric value that does not change






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






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






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

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






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






47. 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
