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.
