From the sum of `233` and `-147 , ` subtract `-284`

Options

A. -370
B. 86
C. 370
D. -86

Answer

To solve the problem step by step, we need to follow these instructions:

**Step 1: Find the sum of 233 and -147.**

To do this, we can rewrite the operation as:
\[ 233 + (-147) \]

Since adding a negative number is the same as subtracting that number, we can rewrite it as:
\[ 233 - 147 \]

Now, we perform the subtraction:
\[ 233 - 147 = 86 \]

So, the sum of 233 and -147 is 86.

**Step 2: Subtract -284 from the sum obtained in Step 1.**

Now we need to subtract -284 from 86:
\[ 86 - (-284) \]

Subtracting a negative number is the same as adding its positive counterpart. Therefore, we can rewrite it as:
\[ 86 + 284 \]

**Step 3: Perform the addition.**

Now, we add 86 and 284:
\[ 86 + 284 \]

To do this, we can align the numbers:
```
86
+284
____
```

Now, we add the digits:
- Start from the right: \( 6 + 4 = 10 \) (write down 0 and carry over 1)
- Next column: \( 8 + 8 = 16 \), plus the carry over 1 gives \( 17 \) (write down 7 and carry over 1)
- Finally, the leftmost column: \( 2 + 1 = 3 \)

So, we have:
```
86
+284
____
370
```

Thus, the final result is:
\[ 370 \]

**Final Answer: 370**
