Our equation

• 
  `(7-9+(9-5)^(2)-4*2+4 )/(-5-1+8-3*100)`

1. Simplifying Parentheses

• 
  `(7-9+4^(2)-4*2+4 )/(-5-1+8-3*100)`

2. Simplifying Exponents

• 
  `(7-9+16-4*2+4 )/(-5-1+8-3*100)`

3. Multiplying

• 
  `(7-9+16-8+4 )/(-5-1+8-300)`

4. Adding (As division without simplifying isn't correct)

• 
  `(7+7-4 )/(-5+7-300)`
• 
  `(14-4 )/(2-300)`
