Introduction

Artsy can be used as a calculator to perform simple arithmetic operations. In this tutorial, we will create a basic calculator that can add, subtract, multiply, and divide numbers using operators and functions.

Setting up the program

To begin, we need to set up our Artsy program. We will create a new Artsy file and declare variables that will hold the values of our operands and the result of our calculations. We will also define a function for each operation we want to perform.

# Declare variables
declare a as int;
declare b as int;
declare result as int;

# Define functions
action int add(int num1, int num2) {
    let result = num1 + num2;
    report result;
}

action int subtract(int num1, int num2) {
    let result = num1 - num2;
    report result;
}

action int multiply(int num1, int num2) {
    let result = num1 * num2;
    report result;
}

action int divide(int num1, int num2) {
    let result = num1 / num2;
    report result;
}

Performing calculations

Now that we have set up our program, we can use it to perform calculations. To do this, we need to assign values to our variables num1 and num2 and then call the function for the operation we want to perform.

For example, to add two numbers, we would assign values to num1 and num2 and then call the add() function:

# Assign values
let a = 10;
let b = 5;

# Call add() function and print result
add(a, b);
print result;
addline;

This code will output 15.0.

Similarly, we can subtract, multiply, and divide numbers by calling the corresponding functions:

# Assign values
let num1 = 10.0;
let num2 = 5.0;

# Call subtract() function and print result
subtract();
print result;
addline;

# Call multiply() function and print result
multiply();
print result;
addline;

# Call divide() function and print result
divide();
print result;
addline;

This code will output:

5.0
50.0
2.0

Conclusion

In this tutorial, we learned how to create a basic calculator using Artsy. We defined functions for each operation we wanted to perform, and then assigned values to our variables and called the corresponding functions to perform calculations. By building upon these concepts, we can create more complex programs that perform more sophisticated calculations.
