a. = 3 + 3 ·30 = 3 + 90 = 93
b. = 5 · ( 120 - 60 ) = 5 ·60 =300
c. = 2 · ( 150 : 50 ) = 2 · 3 = 6
b. = 5 · ( 120 - 60 ) = 5 ·60 =300
c. = 2 · ( 150 : 50 ) = 2 · 3 = 6
a. (3 x 30) + 3 = 90 + 3 =93.
b.5 x (120 - 60) = 5 x 60 = 300
c.2 x (150 : 50) = 2 x 3 = 6.
b.5 x (120 - 60) = 5 x 60 = 300
c.2 x (150 : 50) = 2 x 3 = 6.
