There are a few shortcuts you can use as well in certain circumstances. If you're going to
increment a variable by 1, you can use the increment operator instead (++): a++, instead of using
a standard assignment operation (a = a + 1).
Another instance is when you're adding to the variable in a manner like this: a = a + 4, you can
shorten that up by using the += operator: a+=4
For more information on the increment and self assigning operator, please view the Special
Operators section of the help document.
