To convert an octal number to decimal. The number given is "35". The "(10)" indicates the target base is decimal. The "-(2)2" part is interpreted as subtracting the decimal value 2, which is represent

Step 1: Interpret the problem.
The problem asks to convert an octal number to decimal. The number given is "35". The "(10)" indicates the target base is decimal. The "-(2)2" part is interpreted as subtracting the decimal value 2, which is represented as $10_2$ in binary.

Step 2: Convert the octal number $35_8$ to decimal.
To convert $35_8$ to base 10, we use the formula $d_1 \times 8^1 + d_0 \times 8^0$.

$$35_8 = 3 \times 8^1 + 5 \times 8^0$$ $$35_8 = 3 \times 8 + 5 \times 1$$ $$35_8 = 24 + 5$$ $$35_8 = 29_{10}$$

Step 3: Convert the binary number $10_2$ (from "-(2)2") to decimal.
We interpret "-(2)2" as subtracting the decimal value 2. In binary, the decimal number 2 is represented as $10_2$.
To convert $10_2$ to base 10, we use the formula $d_1 \times 2^1 + d_0 \times 2^0$.

$$10_2 = 1 \times 2^1 + 0 \times 2^0$$ $$10_2 = 1 \times 2 + 0 \times 1$$ $$$$
