Solution

The problem in the image asks for the result of the following arithmetic expression:

75+0+32+64+27 - 5 + 0 + 3 - 2 + 6 - 4 + 2

Let's solve it step by step:

  1. 75=27 - 5 = 2
  2. 2+0=22 + 0 = 2
  3. 2+3=52 + 3 = 5
  4. 52=35 - 2 = 3
  5. 3+6=93 + 6 = 9
  6. 94=59 - 4 = 5
  7. 5+2=75 + 2 = 7

Thus, the result of the expression is 7.

So, the correct answer is B. 7.
