Answer 1

14°15' + 15°14' = 29°29'

29°40' - 13°15' = 16°25'

6°24' × 2 = 12°48'

6°24' : 3 = 2°8'

47°47' + 42°43' = 89°90' = 90°30'

6° - 3°54' = 5°60' - 3°54' = 2°6'

15°13' - 13°15' = 14°73' - 13°15' = 1°58'

30°48' : 6 = 5°8'

27°14' + 72°46' = 99°60' = 100°

23°14' × 2 = 46°28'

73°29' + 64°37' = 137°66' = 138°6'
