5. Remember that Order of Operations says that when it is just addition and subtraction you go from left to right
OpenStudy (mathlegend):
-10 + 25 = 15
15 - 8 = 7
OpenStudy (mathlegend):
6. Order of Operations just addition and subtraction again so we move from left to right again
OpenStudy (mathlegend):
-30 + 14 = 16
16 - 8 = 8
OpenStudy (mathlegend):
16 * - 9 = -144
-144 * 3 = -432

So we have addition and subtraction which calls for us to move from left to right
OpenStudy (mathlegend):
-12.8 + 2.6 = -10.2
-10.2 - 11.9 = -22.1
-22.1 + 6.2 = -15.9
-15.9 + 0.9 = -15
