The answers to this question are A, B, C, and D. You can write down the equation so that you can analyze things better. =sum(b1:b10)-2. =b1+b2+b3+b4+b5+b6+b7+b8+b9+b10 will just allow you to get the sum; =sum(b1:b8)+b9+b10-4. =sum(b1:b5)+sum(b6:b10) is just similar to the one above. =sum(b1:b10) =b1+b2+b3+b4+b5+b6+b7+b8+b9+b10 =sum(b1:b8)+b9+b10; =sum(b1:b5)+sum(b6:b10).

All of these formulas will give you the answer that you want. You cannot choose E because you will need to multiply the given numbers and F will not be ideal as well because the sum that you will get will be incorrect.
