Answer 2

Answer:

Here given

80+[20×{20-(10÷5)}]

we have solve these by using BODMAS rule

so, in these first we are talking inner bracket value. i.e 10÷5 = 2

Next second inner bracket

{20-(10÷5)} = {20-2} = 18

take next bracket. i.e [20×{20-(10÷5)}]

= [20×{20-2}] = [20×18] = 360

next substitute the above value in the given problem. i.e 80+360

440

Ans:- 440
