Question 70

What is the value of

$$36 \div 8 \times 4 + 2 \div 4 - 1 + 5 of 3 \div (4 \times 2 - 3) - 3$$?

Solution

$$36 \div 8 \times 4 + 2 \div 4 - 1 + 5 of 3 \div (4 \times 2 - 3) - 3 $$

$$ = 36 \div 8 \times 4 + 2 \div 4 - 1 + 5 of 3 \div 5 - 3 $$

$$ =36 \div 8 \times 4 + 2 \div 4 - 1 + 15 \div 5 - 3 $$

$$ =\frac{9}{2} \times 4 + \frac{1}{2} - 1 + 3 - 3 $$

$$ =18 + \frac{1}{2} - 1 + 3 - 3 $$

$$ =18 + \frac{1}{2} + 3 - 4 $$

$$ = \frac{35}{2} $$
