Across
  1. 3. This is a combination of scientific and standard notation. It is a way of writing a number as the sum of its digits multiplied by their place values.
  2. 5. A number that results from multiplying an integer times itself. It can be represented in the shape of a square.
  3. 8. A number is negative if it is less than zero.
  4. 10. An arrangement from the smallest to the largest number (least to greatest)
  5. 13. The number written on the top of a fraction. It represents how many parts one has out of a given whole.
  6. 15. The straightforward expression of a number written in its normal form.
  7. 16. A number or ratio that can be expressed as a fraction over 100.
  8. 17. A straight line that connects two opposite corners of a shape.
  9. 18. A whole number and its opposite that can be positive, negative, or zero. Integers do not include fractions.
  10. 20. A type of number which has a whole number and a fractional part separated by a decimal point.
  11. 21. A statement or phrase that combines numbers and/or variables using mathematical operations. Expressions do not have equal signs.
  12. 22. A number that can be expressed as a fraction and whose decimal value is terminating, repeating, or shows a distinct pattern.
  13. 25. An arrangement from the largest to the smallest number. (greatest to least)
  14. 27. A straight line starting with zero in the middle and numbers placed equal distances from each other extending in both the positive and negative direction to infinity.
  15. 28. An irrational number that never ends but is usually rounded to 3.14. It is represented by the symbol below.
  16. 30. A factor of a number that can be multiplied times itself to get the original number.
  17. 31. describes how far away the number is from zero on the number line. The absolute value of a number is never negative.
  18. 35. A way of writing very large or very small numbers using a coefficient between 1 and 10 multiplied by a base of 10 raised to the power of n.
Down
  1. 1. A number that is NOT the square of a natural number. These numbers have square roots that are irrational.
  2. 2. A smaller group in which all the elements are contained within a larger set.
  3. 4. A collection of objects or elements grouped together in braces or parenthesis.
  4. 6. arranging or sorting objects into groups based on common characteristics.
  5. 7. A set of numbers including all the positive integers from 1 to infinity. These are also called counting numbers. Zero is not a part of this category.
  6. 9. A small symbol that is written above and to the right of a number or variable to show how many times it is to be multiplied times itself.
  7. 11. A set of numbers including all natural numbers and zero. They are a part of real numbers that DO NOT include fractions, decimals, or negative numbers.
  8. 12. A number whose decimal value is non-terminating, non-repeating, and shows no distinct pattern.
  9. 14. different representations that may look different by represent the same value.
  10. 19. The number written on the bottom of a fraction. It represents the number of parts into which one whole is divided.
  11. 23. A calculation using a mathematical process. The most common are add, subtract, multiply and divide.
  12. 24. The union of both rational and irrational numbers. They can be positive or negative, large or small, whole or decimal numbers and fractions.
  13. 26. A number is positive if it is greater than zero.
  14. 29. A diagram which shows the relationship between sets of data or values in an organized manner.
  15. 32. An illustration used to visually represent sets and which elements belong to each set by drawing regions around them.
  16. 33. A part of a whole in which a numerator is divided by a denominator.
  17. 34. The process of changing a value or expression from one form to another.
