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






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






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






5. Same shape - but different size






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






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






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






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






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






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






12. Numeric value that does not change






13. 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






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






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






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






17. Same shape - but different size






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






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






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






21. (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.






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






23. 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






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






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






26. 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)






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






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






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






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






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






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






33. Numeric value that does not change






34. 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.






35. 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






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






37. 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)






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






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






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






41. 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).






42. 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.






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






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