Explicație pas cu pas:
a) 33⁰18'+44⁰24' = 77°42'
d) 125⁰-24⁰53' = 124°60'-24°53' = 7'
g) 135⁰:4 = 33°+3·60':4 = 33°45'
j) 34⁰18'23''+18⁰25'32'' = 52°43'55''
b) 25⁰38'+28⁰53' = 53°91' = 54°31'
e) 27⁰13'×4 = 108°52'
h) 122⁰50':5 = 24°+(2·60'+50'):5 = 24°34'
k) 5×(41⁰10'11'') = 205°50'55''
c) 75⁰53'-28⁰23' = 47°30'
f) 27⁰53'×5 = 135°265' = 139°25'
i) 80⁰-113⁰6':3 = 80°-(37°+126':3) = 80°-37°42' = 79°60'-37°42' = 42°18'
l) 171⁰53'48''-63⁰29'34" = 108°24'14''
------------------------
1° = 60' ; 1' = 60''
