Answer:
-9.7 + 18.6
Step-by-step explanation:
Given the expression:
-9.7 - (-18,6)
The additive inverse of -18.6 is 18.6
The product of teo negative sign will also give a positive sign, hence:
-9.7 - (-18,6) = -9.7 + 18,6
-9.7 + 18,6 = 18.6 - 9.7
18.6 - 9.7 = 8.9
Hence the expression can also be written as -9.7 + 18.6 with 8.9 being the solution
