The first things to do is to count the number of TERMS.
These are separated by + and - minus signs.

Find an answer for each term first and then in the last step, add or subtract the answers to get the final result.

#50 color(orange)+ 24÷2xx10 color(orange)- 15 " has 3 terms"#

#color(blue)50 + color(red)(24÷2xx10) - color(purple)15 " get 3 answers"#

#=color(blue)50 + color(red)(12xx10) - color(purple)15#

#=color(blue)50 + color(red)(120) - color(purple)15 " work left to right"#

#=155#
