COMPOUND ASSIGNMENT
7+
in this section, we will work with our compound assignment operators

9+
10+
declare an integer variable with the value of 1
11+
then, using compound assignment and the System.out.println() operation to check your results,
12+
complete the following steps in order:
13+
1. add 3 to your variable
14+
2. multiply your variable by 4
15+
3. subtract 8 from your variable
16+
4. divide your variable by 2
17+
5. modulus your variable by 3
18+
19+
the final result should be a variable that holds the original value of 1
