Answer: 399

Step-by-step explanation:

For this you are going to use

PEMDAS or Please Excuse My Dear Aunt Sally.

P-parentheses

E-exponents

M-multiplication

D-division

A-addition

S-subtraction

You will use this system for every equation. First you do whatever is in your parentheses. (20-8)=12 Then you do your exponents. Which is 4x4x4=64. You then do any multiplication or division in the problem 64x12=768. You then divide by 2 which equals 384. You then add 6 and 9. Which equals 399.

Answer is 399 !
