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






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






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






4. 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.






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






6. 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






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






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






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






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






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






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






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






14. 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






15. Same shape - but different size






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






17. A quantity that does not vary






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






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






20. 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






21. 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






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






23. 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)






24. Statement that two fractions or ratios are equal






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






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






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






28. 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






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






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






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






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






34. 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).






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






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






37. The reciprocal of a number.






38. Numeric value that does not change






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