Follow BODMAS rule to solve this question, as per the order is given below: Step-1: Parts of an equation enclosed in ‘Brackets’ must be solved first and in the bracket, Step-2: Any mathematical ‘Of’ or ‘Exponent’ must be solved next, Step-3: Next, the parts of the equation that contains ‘Division’ and ‘Multiplication’ are calculated, Step-4: Last but not least, the parts of the equation that contain ‘Addition’ and ‘Subtraction’ should be calculated. Given expression is, ⇒ 8÷4+2−(6×8÷2)+(7×4−2×2)72÷9+3−6−(2×3)+5of3−(1+5×2−2) = ? ⇒ ? = 8÷4+2−(6×28)+(28−4)72÷9+3−6−6+5of3−(1+10−2) ⇒ ?=48+2−24+24972+3−6−6+15−9 ⇒ ?=2+28+3−12+6 ⇒ ? = 5/4
