Question 17

$$80 \div [48- \left\{56 - (60- 36 \div 12 \times 4)\right\}] =$$

Solution

$$80 \div [48- \left\{56 - (60- 36 \div 12 \times 4)\right\}]$$

First solve the small bracket with BODMAS rule.

$$80 \div [48- \left\{56 - (60- 12)\right\}]$$

Now solve the curly bracket with BODMAS rule.

$$80 \div [48- \left\{56 - 48\right\}]$$

Lastly solve the big bracket with BODMAS rule.

$$80 \div [48- \left\{8\right\}]$$

$$\frac{80}{40}$$
