Order of Operations 0.3 Practice Problem 24

Based on the PDF the answer is 3, but I computed it manually and using a calculator. the answer is 5. and I’m getting the answer on both systems.
here’s the question:
(13+(-3)^(2)+4(-3)+1-[-10-(-6)])/({[4+5]-:[4^(2)-3^(2)(4-3)-8]}+12)

thank you for clarifications.
