  1. 3. The number being multiplied by a term. In scientific notation, it is the number being multiplied by the base 10 power.
  2. 4. 3-dimensional figure with all equal sides (length, width, and height). Also the act of using a base as a factor 3 times.
  3. 5. A number whose cube root is a whole number
  4. 7. Decimals that never terminate, but never repeat and cannot be placed on a precise place on a number line without rounding; the root of imperfect radicals; fractions with irrational numbers in the numerator or denominator
  5. 8. A method of writing very large or very small numbers by using powers of 10. Written as a coefficient less than 10 multiplied by the power of 10 that would recreate standard form.
  6. 11. A number that can be expressed as a fraction made of two integers, a decimal that terminates, or a decimal that repeats
  7. 13. The positive square root of a number
  8. 17. Positive or negative rational numbers whose value is not a decimal (…-3,-2,-1,0,1,2,3…)
  9. 19. A decimal number that ends, terminates, or stops
  10. 25. An irrational number that represents the circumference of a circle compared to the length of its diameter. π ≈ 3.14 or 22/7
  11. 26. A rational or irrational number
  12. 27. 2-dimensional figure with all equal sides (length and width). Also the act of using a base as a factor twice.
  13. 28. A base multiplied as a factor 3 times to become a product

  1. 1. A number without fractions or decimals
  2. 2. A number bigger than zero
  3. 6. A rational number that can be discovered without a calculator and be used to represent an irrational number due to its proximity to the actual irrational number
  4. 9. A side of 3-dimensional figure
  5. 10. A decimal in which one or more digits repeat infinitely without terminating.
  6. 12. Positive integers and the number 0 (0,1,2,3…)
  7. 14. A number whose square root is not a whole number
  8. 15. The normal way of writing numbers expressed so there are no operations to perform to identify the number's value.
  9. 16. A number less than 0
  10. 18. A number whose square root is a whole number
  11. 20. Symbol that represents finding the root of a number √. The number in the hook of the symbol implies which root to find. √=square root, ∛=cube root, ∜=fourth root, etc.
  12. 21. Positive integers (1,2,3…)
  13. 22. The set of whole numbers and their opposites
  14. 23. A base multiplied as a factor 2 times to become a product
  15. 24. the great size or extent of something.
