How do you solve step by step (-10)+14+25+(-16)

(-10) + 14 + 25 + (-16)   Add 14 and 25
    (-10) + 39 + (-16)      Change 39 + (-10) to 39 - 10
      (-10) + 39 - 16        Subtract 16 from 39
          (-10) + 23          Change (-10) + 23 to 23 - 10
            23 - 10            Subtract 10 from 23
                13 

*Remember, you can rearrange expressions like this as long as each number keeps its sign. Notice that (-10) had its negative sign the whole time, even though we moved it around.
