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






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






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






4. 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






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






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






7. Statement that two fractions or ratios are equal






8. 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.






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






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






11. 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






12. 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






13. 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).






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






15. (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.






16. A function whose graph is a straight line.






17. 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.






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






19. 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






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






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






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






23. The reciprocal of a number.






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






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






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






27. 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






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






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






31. 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)






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






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






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






35. 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






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






37. The reciprocal of a number.






38. 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






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






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