In Python, numbers without a decimal point are called Integers - just like they are in mathematics.
Integers are simply whole numbers, positive or negative. For example, 3 and -3 are both examples of integers.
Arithmetic can be performed as you might expect:
2 + 1
# 3
2 - 1
# 1
2 * 2
# 4
3 / 2
# 1.5 (a float)
This one is actually a bit different - division on two integers will actually produce a float. A float is, as you may have guessed, the number type that allows for decimal values.
