Answer 1

9/20+3(4-1)-7+
`2^(3)`

BODMAS stands for B-Brackets, O-Orders (powers/indices or roots), D-Division, M-Multiplication, A-Addition, S-Subtraction.

=9/2+12-3-7+
`2^(3)` Brackets is solved ..........3(4-1

=9/2+12-3-7+8 Orders(powers................
`2^(3)`

=4.5+12-3-7+8 Division.............................9/2

=16.5-3-1 Addition..............................4.5+12 & -7+8

=12.5
