- 1, 2, 3, 4, 5
- 1.0, 2.0

declaration + initialization
- int num = 17;
- double num = 25.0;
- char temp = 'c';
- String name = "Charlie";

modular arithmetic
- remainder
- mudlo takes the same arguments as division, but outputs only the remainder
- ex: 9 mod 7 = 2 because 9/7 = 1 remainder 2
- modulo "wrap around" property
- consider a clock, where we are taking all values and modding them by 12
