`100 xx 10 - 100 + 2000 div 100` = ?

Options

A. 29
B. 920
C. 980
D. 1000

Answer

To solve the expression \(100 \times 10 - 100 + \frac{2000}{100}\), we will follow the BODMAS/BIDMAS rule, which stands for Brackets, Orders (i.e., powers and square roots, etc.), Division, Multiplication, Addition, and Subtraction.

### Step-by-step Solution:

1. **Identify the operations**: The expression consists of multiplication, subtraction, addition, and division.
\[ 100 \times 10 - 100 + \frac{2000}{100} \]

2. **Perform the division**: According to BODMAS, we first handle the division.
\[ \frac{2000}{100} = 20 \]
Now, substitute this back into the expression:
\[ 100 \times 10 - 100 + 20 \]

3. **Perform the multiplication**: Next, we perform the multiplication.
\[ 100 \times 10 = 1000 \]
Now, substitute this back into the expression:
\[ 1000 - 100 + 20 \]

4. **Perform the subtraction**: Now, we subtract 100 from 1000.
\[ 1000 - 100 = 900 \]
Now, substitute this back into the expression:
\[ 900 + 20 \]

5. **Perform the addition**: Finally, we add 20 to 900.
\[ 900 + 20 = 920 \]

### Final Answer:
The final result of the expression \(100 \times 10 - 100 + \frac{2000}{100}\) is \(920\).
