  • Scientific Notation
    A method expressing numbers as a coefficient multiplied by ten raised to an exponent, simplifying calculations with very large or small values.
  • Exponent
    A value indicating the power to which ten is raised, determining the scale or magnitude in scientific notation.
  • Coefficient
    The numerical factor in scientific notation that is added or subtracted when exponents are equal.
  • Decimal Places
    The number of digits to the right of the decimal point, which determines the precision of the final result.
  • Precision
    The degree to which repeated calculations yield the same result, maintained by matching decimal places in answers.
  • Transformation
    The process of adjusting a value so its exponent matches another, enabling direct addition or subtraction.
  • Calculation
    A mathematical process involving addition or subtraction of values, often performed without a calculator for accuracy.
  • Value
    A quantity expressed in scientific notation, consisting of a coefficient and an exponent.
  • Constant
    A property of the exponent in scientific notation during addition or subtraction, ensuring it remains unchanged.
  • Accuracy
    The closeness of a calculated result to the true value, achieved by following proper addition or subtraction rules.
  • Communication
    The clear expression of numerical results, enhanced by using correct scientific notation and precision.
  • Method
    A systematic approach for adding or subtracting values in scientific notation, especially without a calculator.
