Order of operations.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

We must do parenthesis first.

72 - 13 = 59

We have now
20 + 15(59) - 67 + 6
20 + 885 - 67 + 6
905 - 67 + 6
905 - 61
844

Hope this helped! If you have any questions then leave a comment.

Good morning

20+15(72-13)-67+6

= 20+15(59)-67+6

= 20+885-67+6

= 905-67+6

= 838+6

= 844


I hope that's help !


Happy Sunday :)
