What is the value of $$90 \times 3 \div 9 + 4 \div 2 \times 3 of 4 \times 8 \div (18 \times 2 - 4)$$?

Solution

$$90 \times 3 \div 9 + 4 \div 2 \times 3 of 4 \times 8 \div (18 \times 2 - 4)$$

$$30 + 4 \div 2 \times 12\times 8 \div 32$$

$$30 + 2 \times 12\times 8 \div 32$$

$$30 + 2 \times 12\div 4$$
