You begin a hike in death valley, California,at -86 meters.You hike to a point of elevation at 45 meters. What is your change in elevation

86 + 45 = ?

131

To find the change in elevation, you subtract the initial elevation from the final elevation.

Change in elevation = Final elevation - Initial elevation

Given:
Initial elevation = -86 meters
Final elevation = 45 meters

Substituting the values into the formula, we have:

Change in elevation = 45 meters - (-86 meters)

Now, to subtract a negative number, you can change the subtraction to addition and change the sign of the negative number:

Change in elevation = 45 meters + 86 meters

Performing the addition:

Change in elevation = 131 meters

Therefore, your change in elevation is 131 meters.
