Solution:
According to PEMDAS rule,
- [First parenthesis]
[tex] = 14 + 16 \div {2}^{3} - (12 + 9 ) \div 7 + 2 \times ( - 5)[/tex]
[tex] = 14 + 16 \div {2}^{3} - 21 \div 7 + 2 \times ( - 5)[/tex]
- [Then exponents]
[tex] = 14 + 16 \div 8 - 21 \div 7 + 2 \times ( - 5)[/tex]
- [Then multiplication]
= 14 + 16 ÷ 8 - 21 ÷ 7 - 10
- [Then division]
= 14 + 2 - 3 - 10
- [Then addition]
