The  value of 4 × 3 ÷ 2 of 3 × 2 ÷ (4 + 5 × 4 ÷ 4 of 5 - 4 ÷ 4 × 4) is :

4

Using BODMAS, 4 × 3 ÷ 2 of 3 × 2 ÷ (4 + 5 × 4 ÷ 4 of 5 - 4 ÷ 4 × 4) = 4 × 3 ÷ (2 × 3) × 2 ÷ (4 + 5 × 4 ÷ (4 × 5) - 4 ÷ 4 × 4)

= 4 × [3 × \(\frac{1}{2}\) × \(\frac{1}{3}\)) × 2 ÷ (4 + 5 × 4 × \(\frac{1}{4}\) × \(\frac{1}{5}\) - 4 × \(\frac{1}{4}\) × 4)

= 4 × \(\frac{1}{2}\) × 2 ÷ ((4 + 1) - 4)

= 2 ×  2 ÷ 1

= 2 × 2 = 4
