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 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.






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






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






6. 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






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






8. (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.






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






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






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






12. Same shape - but different size






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






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






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






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






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






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






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






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






23. Numeric value that does not change






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






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






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






27. 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)






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






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






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






31. 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






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






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






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






35. The reciprocal of a number.






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






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






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






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






40. 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






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






42. A function whose graph is a straight line.






43. A quantity that does not vary






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