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 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.






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






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






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






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






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






7. Statement that two fractions or ratios are equal






8. 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)






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






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






11. Statement that two fractions or ratios are equal






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






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






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






15. 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






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






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






18. 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






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






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






21. 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)






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






23. Same shape - but different size






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






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






26. 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.






27. 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






28. 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






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






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






31. A function whose graph is a straight line.






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






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






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






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






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






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






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






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






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






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






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






43. 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.






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






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