Solve 2³ -1 • (3 + 6) + 3

P E M D A S 8 - 1 ● 9 + 3
A X U I D U
R P L V D B (3 + 6) = 9
E O T I I T 2^3 = 8
N N I D T R
T E P E T A
H N L I C
E T Y O T THE ANSWER IS 2
S N I 8 - 9= -1
I O -1 + 3 = 2
S N

pemdas parenthesis (3 + 6) are first
exponent 2^3 is next
multiply 1 ● 9 goes next
divide here was none
add 1 + 3
subtract 8 - 9

if it is division is in front of multiplication going left to right, then divide first. if subtraction is in front of addition going left to right, subtract.

hope this helps ^_^
