  1. Degrees Minutes & Seconds 360° in a circle 1° = 1/360 of a circle 1’ = 1/60 of one degree 1” = 1/60 of one minute 1° = 60 minutes or 3600 seconds

  2. Adding DMS • Examples 25° 22’ 15” + 60° 15’ 49” 85° 37’ 64” or 85° 38’ 04” 55° 55’ 43” + 67° 43’ 29” 122° 98’ 72” or 123° 39’ 12”

  3. Subtracting DMS • Examples 125° 43’ 32” - 44° 11’ 22” 81° 32’ 10” 235° 10’ 37” or 234° 69’ 97” - 140° 59’ 59” - 140° 59’ 59” 94° 10’ 38”

  4. Converting DMS to Decimal 94° 30’ 30” 30”/60 = .5’ add to minutes 30.5/60 = .5083° 94° 30’ 30” = 94.5083°

  5. Your Turn 55° 23’45” + 120° 45’ 33” = 44°44’44” + 25°55’23” = 132°34’ 55” - 68°49’52” = 43°35’48” - 22°56’13” = 176°09’18” 70°40’07” 63°45’03” 20°39’35”

  6. More Fun 176°09’18” 70°40’07” 63°45’03” + 20°39’35” 331°14’03” Now convert 331°14’03” to Decimal Degrees 331.2342°
