    Study Notes

    Negative Numbers

    • Negative numbers represent values less than zero.
    • The further a negative number is from zero, the smaller its value.
    • For example, -3 is smaller than -1.

    Adding and Subtracting Integers

    • When adding a positive number to a negative number, the result is closer to zero.
    • When subtracting a positive number from a negative number, the result is further from zero.

    Real World Application

    • Luisa's starting location is 43 feet below sea level, represented as -43 feet.
    • Climbing a 14 feet ladder moves her 14 feet closer to the surface.
    • To determine her new location, we subtract 14 from -43, resulting in -29 feet.

    Calculating Elevation Differences

    • Mount Whitney's elevation is 14,494 feet above sea level, represented as +14,494 feet.
    • Death Valley's elevation is 282 feet below sea level, represented as -282 feet.
    • The difference in elevations is calculated by finding the sum of their absolute values: 14,494 + 282 = 14,776 feet.

    Temperature

    • -3° is a negative temperature

    Word Problems

    • Luisa is 43 feet below ground level and climbs 14 feet up.
    • To find her new location, subtract the distance she climbed from her initial depth: -43 feet + 14 feet = -29 feet
    • Therefore, Luisa's new location is 29 feet below ground level.

    Elevation

    • Mount Whitney is at 14,494 feet above sea level.
    • Death Valley is 282 feet below sea level.
    • To find the difference in elevations, add the absolute values of the two elevations: 14,494 feet + 282 feet = 14,776 feet.
    • The difference in elevation between Mount Whitney and Death Valley is 14,776 feet.

    Number Line and Integers

    • -3° is a negative number and represents a temperature below zero degrees.

    Adding and Subtracting Integers

    • Luisa starts at -43 feet underground and climbs 14 feet up.
    • Her new location is -29 feet underground.

    Elevation Differences

    • Mount Whitney's elevation is 14,494 feet above sea level.
    • Death Valley's elevation is 282 feet below sea level.
    • The difference in elevations is 14,776 feet.
