Yes, parenthesis, exponents, multiplication, division, addition, subtraction.
PEMDAS
Unless, subtraction comes first (on the left)
Example:
1)
2+5*8-4
5*8 = 40
40+2 = 42
42-4 = 38
2) 4-5*8+9
5*8 = 40
40-4 = 36
36+9 = 45
Although sometimes you get the same answer from doing either first

23,598 because 513 x 40 = ( 500 x 40 ) + ( 10 X 40 ) + ( 3 x 40 ) = 20 000 + 400 + 120 = 20,520 and another partial product is 513 x 6 = ( 500 x 6 ) + ( 10 x 6 ) + ( 3 x 6 ) = 3 000 + 60 + 18 = 3,078. so 20,520 + 3,078 = 23,598
