1. 3. numbers is a real number that is less than zero.
  2. 6. the top number (the numerator) says how many parts we have.
  3. 9. The bottom number in a fraction.
  4. 12. expression is a mathematical phrase that can contain ordinary numbers, variables
  5. 16. product or scalar product (sometimes inner product in the context of Euclidean space, or rarely projection product for emphasizing the geometric significance), is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors) and returns a single number.
  6. 17. number that a numerator and denominator becomes when it is reduced by its greatest common factor.
  7. 19. coefficient is defined as a fixed number that is multiplied to a variable. So in the expression. 3x + 2y + 4. as Aswini says, 3 is the coefficient of x, 2 is the coefficient of y, but, in my example, 4 is not a coefficient, as it is not being multiplied by a variable. It is a fixed value.
  8. 20. Number can be divided evenly only by 1, or itself. And it must be a whole number greater than geometry The branch of mathematics that treats the properties, measurement, and relations of points, lines, angles, surfaces, and solids.
  1. 1. is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.
  2. 2. common factor 2 numbers is the smallest number that they both divide evenly
  3. 4. common factor between 2 numbers is the largest factor that they have in common. One good way to find this number is to write down all the factors of both numbers and then find the biggest one that appears in both lists.
  4. 5. numbers which follow each other in order, without gaps, from smallest to largest. 12, 13, 14 and 15
  5. 7. expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials.
  6. 8. a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression
  7. 10. expression A real number that can NOT be made by dividing two integers.
  8. 11. test what is used to factor polynomials of the form Ax� + Bx + C. A, B, and C represent constants and x is the variable.
  9. 13. The highest number that divides exactly into two or more numbers?
  10. 14. uses letters (like x or y) or other symbols in place of values, and plays with them using special rules.
  11. 15. numbers Numbers can be positive, negative or zero.
  12. 18. The top number in a fraction.
