Evaluate the following :
`-77+(-84)+318`

Answer

To evaluate the expression \(-77 + (-84) + 318\), we will follow these steps:

### Step 1: Rewrite the expression
The expression is given as:
\[ -77 + (-84) + 318 \]
We can rewrite it by recognizing that adding a negative number is the same as subtracting that number:
\[ -77 - 84 + 318 \]

### Step 2: Combine the negative numbers
Now, we will combine the negative numbers \(-77\) and \(-84\):
\[ -77 - 84 = -(77 + 84) \]
Calculating \(77 + 84\):
\[ 77 + 84 = 161 \]
So,
\[ -77 - 84 = -161 \]

### Step 3: Add the result to 318
Now we will add \(-161\) to \(318\):
\[ -161 + 318 \]
To perform this addition, we can think of it as:
\[ 318 - 161 \]

### Step 4: Calculate \(318 - 161\)
Now, we will calculate \(318 - 161\):
\[ 318 - 161 = 157 \]

### Step 5: Determine the sign
Since \(318\) is greater than \(161\), the result will be positive. Therefore, the final answer is:
\[ \boxed{157} \]
