**SAS Functions [1-14]**

**Mathematical Operators**

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.

*Need some help?*

**HINT: **

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

**SOLUTION: **

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**.
