The given equation:
2 ÷ 2 × 312 + 12 - 54 = 0
BODMAS Rule:Interchanging the signs and using BODMAS rule:-
(i) + and -
2 ÷ 2 × 312 - 12 + 54
1 × 312 - 12 +54
312 - 12 + 54
366 - 12
354 ≠ 0
(ii) × and ÷
2 × 2 ÷ 312 + 12 - 54
2 × 0.0064 + 12 - 54
0.0128 + 12 - 54
12.0128 - 54
-41.9872 ≠ 0
(iii) × and -
2 ÷ 2 - 312 + 12 × 54
1 - 312 + 12 × 54
1 - 312 + 648
649 - 312
347 ≠ 0
(iv) + and ÷
2 + 2 × 312 ÷ 12 -54
2 + 2 × 26 - 54
2 + 52 - 54
54 - 54
0 = 0
Hence, the correct answer is "+ and ÷".
