**Mathematical Operators**

```
Var3 = Var1 + Var2;
Var3 = Var1 - Var2;
Var3 = Var1 * Var2;
Var3 = Var1 / Var2;
```

Let's start with something simple.

Below is the **NUMBERS** data set.

It contains 2 variables: VAL1 and VAL2.

Note: the yellow box below contains the code for the **NUMBERS** data set.

Copy and run the code to get the **NUMBERS** data set on SAS Studio.

To add, subtract, multiply and divide values in SAS, you can use the following mathematical operators:

**Add & Subtract**

```
Data Math1;
Set Numbers;
val3 = val1 + val2;
val4 = val1 - val2;
Run;
```

**Multiplication & Division**

```
Data Math2;
Set Numbers;
val3 = val1 * val2;
val4 = val1 / val2;
Run;
```

**Exercise**

Copy and run the **ACCOUNTING** data set from the yellow box below.

**ACCOUNTING** contains 4 variables:

**EmployeeID: **ID**Base:** Base Salary**OTHours: **Overtime Hours**Rate: **Overtime Rate

Employee's salary is calculated as Base Salary + (Overtime Hours x Overtime Rate)

Write a SAS program to calculate the salary for each employee. Create any data set or variables if necessary.

You must create a new variable that contains the salary information based on the equation provided.

Data EmpSalary;

Set Accounting;

Salary = Base + OTHours*Rate;

Run;

Note: The data set we created is called **EMPSALARY**. You do not need to follow our data set naming convention. You can name your data set any way you want. Same for the variable **SALARY**.
