## Example Questions

### Example Question #21 : How To Find Order Of Operations

Explanation:

When doing operations of subtraction and addition, there is no priority but we must work from left to right. The difference on the left is . Since  is greater than  and is negative, we treat as a normal subtraction problem. The same applies for the right side in which  is greater than  and is positive. The answer is .

### Example Question #22 : How To Find Order Of Operations

Explanation:

There is multiplication and addition present. Remember PEMDAS. Multiplication comes first followed by addition.

### Example Question #23 : How To Find Order Of Operations

Explanation:

There is multiplication and addition present. Remember PEMDAS. Multiplication comes first followed by addition. Since there are two multiplication operations, we work from left to right then finally add the products.

### Example Question #24 : How To Find Order Of Operations

Explanation:

When there's multiplication and division, they have the same priority. We will work from left to right.

### Example Question #25 : How To Find Order Of Operations

Explanation:

When there's multiplication and division, they have the same priority. We will work from left to right.

### Example Question #26 : How To Find Order Of Operations

Explanation:

Although there is just addition and subtraction, a paranthesis is present. According to PEMDAS, paranthesis has priority over all operations.

### Example Question #27 : How To Find Order Of Operations

Explanation:

Even there is multiplication, addition and subtraction, a paranthesis is present. According to PEMDAS, paranthesis has priority over all operations.

### Example Question #28 : How To Find Order Of Operations

Explanation:

In PEMDAS, the paranthesis comes first followed by the exponent. We have subtraction so the difference is . We square this to get .

### Example Question #29 : How To Find Order Of Operations

Explanation:

In PEMDAS, the paranthesis comes first.

Next, multiplication and division is next and we work from left to right. Lastly, we add.
