For this case we must solve the following expression:

[tex]15-7 + 2[/tex]

By law of signs of the sum we have to comply:

  • Equal signs are added and the same sign is placed.
  • Different signs are subtracted and the major sign is placed.

So, we have:

[tex]+ 8 + 2 = 10[/tex]

Finally we have to:

[tex]15-7 + 2 = 10[/tex]
