5. Addition
6. Subtraction

Our equation

• $\frac{7-9+(9-5)^{2}-4*2+4 }{-5-1+8-3*100}$

1. Simplifying Parentheses

• $\frac{7-9+4^{2}-4*2+4 }{-5-1+8-3*100}$

2. Simplifying Exponents

• $\frac{7-9+16-4*2+4 }{-5-1+8-3*100}$

3. Multiplying

• $\frac{7-9+16-8+4 }{-5-1+8-300}$

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

• $\frac{7+7-4 }{-5+7-300}$
• $\frac{14-4 }{2-300}$

5. Subtracting

• $\frac{10 }{-298}$

6. Dividing

• $-\frac{5}{149}$ [Simplest fractional answer]
• -0.03 [Simplest decimal answer]
