So, the correct answer is $11$.

To solve $9-7+4+5$:

1. Start with the first operation: $9 - 7 = 2$.

2. Next, add 4:$2 + 4 = 6$.

3. Finally, add 5:$6 + 5 = 11$.

So, the correct answer is $11$.

To solve $15+5-10+3$:

1. Start with the first operation: $15 + 5 = 20$.

2. Next, subtract 10: $20 - 10 = 10$.

3. Finally, add 3: $10 + 3 = 13$.

So, the correct answer is $13$.

To solve $15-5-4+6$, follow these steps:

1. Start with the first operation: $15-5 = 10$.
2. Next, subtract 4: $10-4 = 6$.
3. Finally, add 6: $6+6 = 12$.

Thus, the answer is $12$.

To solve the expression $8+3-2+4$, we follow the order of operations, specifically focusing on addition and subtraction from left to right.
Step 1: Add the first two numbers: $8+3=11$.
Step 2: Subtract the next number: $11-2=9$.
Step 3: Add the final number: $9+4=13$.
Therefore, the correct answer is $13$.

To solve the expression $6-2+5-3$, follow the order of operations, performing addition and subtraction from left to right.
Step 1: Subtract the first two numbers: $6-2=4$.
Step 2: Add the next number: $4+5=9$.
Step 3: Subtract the final number: $9-3=6$.
Therefore, the correct answer is $6$.

To solve the expression $18-2-5+9$, we follow the order of operations. Since there are only addition and subtraction operations, we can solve from left to right:

$18-2$ gives us $16$.

Then, $16-5$ gives us $11$.

Finally, $11+9$ gives us $20$.

So, the correct answer is $20$.

To solve $11-3-4+8$, you apply the operations from left to right, following the order of operations.

Start with the first two numbers and subtract:

$11 - 3 = 8$

Then take the result and subtract the next number:

$8 - 4 = 4$

Finally, add the last number:

$4 + 8 = 12$

Thus, the correct answer is $12$.

To solve the expression $3+5+4-6$, follow these steps:

Step 1: Add the first two numbers: $3 + 5 = 8$.

Step 2: Add the next number to the result: $8 + 4 = 12$.

Step 3: Subtract the last number from the result: $12 - 6 = 6$.

Therefore, the answer is $6$.

To solve the expression $7+2+1-4$, follow these steps:

Step 1: Add the first two numbers: $7 + 2 = 9$.

Step 2: Add the next number to the result: $9 + 1 = 10$.

Step 3: Subtract the last number from the result: $10-4=6$.

Therefore, the answer is $6$.

According to the order of operations, we will solve the exercise from left to right since the only operations in it are addition and subtraction:

$90-2=88$

$88+9=97$

$97-8=89$

$100+5-100+5=105-100+5=5+5=10$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$25+6=31$

$31-19=12$

$12+7=19$

According to the rules of the order of arithmetic operations, we solve the exercise from left to right since it only has addition and subtraction operations:

$3+4=7$

$7-1=6$

$6+40=46$

To solve$20-4+6-5$:

1. Start with the first operation:$20 - 4 = 16$.
