Answer 2

a)
= [43 + (3 + 2 x 7) x 2 - 45] x 2
= [43 + (3 + 14) x 2 - 45] x 2
= [43 + 17 x 2 - 45] x 2
= [43 + 34 - 45] x 2
= [77 - 45] x 2
= 32 x 2

= 64
---------------------------------------------------------------------
= {44 - [(32 - 27) x 3 - 2] x 2} + (42 - 27) x 3
= {44 - [(5 x 3 - 2] x 2} + 15 x 3
= {44 - [15 - 2] x 2} + 45
= {44 - 13 x 2} + 45
= {44 - 26} + 45
= 18 + 45

= 63
