155

#### Explanation:

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"

$= \textcolor{b l u e}{50} + \textcolor{red}{12 \times 10} - \textcolor{p u r p \le}{15}$

$= \textcolor{b l u e}{50} + \textcolor{red}{120} - \textcolor{p u r p \le}{15} \text{ work left to right}$

$= 155$
