1Absolute Value
2The Structural Procedure
  1. Absolute value represents distance on a number line, never direction
  2. Distance is always positive or zero: |-7| = 7 and |7| = 7
  3. Context: Magnitude of temperature, debt, elevation regardless of sign
3Mathematical Word Bank
  • Integers and Absolute Value (Enteros y valor absoluto) — Integers are whole numbers and their opposites; absolute value is their distance from zero.
  • Integer (Número entero) — Whole numbers and their opposites, like -2, -1, 0, 1, 2.
  • Positive (Positivo) — A number bigger than zero, to the right of zero on a number line.
  • Negative (Negativo) — A number smaller than zero, to the left of zero on a number line.
  • Absolute value (Valor absoluto) — How far a number is from zero. It is never negative.
  • Opposite (Opuesto) — Two numbers the same distance from zero, on opposite sides, like 3 and -3.
4Watch out
  • A common mistake in Integers and Absolute Value is judging size by the digits alone instead of position on the number line — students think -8 is 'more' than -3 because 8 > 3, when really -8 sits farther left (colder, deeper, or lower) and is actually the SMALLER integer. Absolute value measures distance from zero and is always positive or zero, but that distance does not decide which integer is greater — only left-to-right order on the number line does. Before you submit, ask: am I comparing distance from zero (absolute value) or position on the number line (greater/less than)?

  5. 5 MULTIPLE CHOICE

    Captain Vega compares |-12| (a deep cave) and |7| (a hilltop). Which absolute value is GREATER?

    1. A|-12| because 12 > 7
    2. B|7| because 7 is positive
    3. CThey are equal
    4. D|-12| = -12, so |7| is greater
