Arithmetic

a is 3

b is 2

a + b is 5

a - b is 1

a * b is 6

a / b is 1.5

a % b is 1

a ^ b is 9

-a is -3

Relational

a is 3

b is 2

a == b is false

a ~= b is true

a < b is false

a > b is true

a <= b is false

a >= b is true

Logical

a is 3

b is 2

a < b and b < a is false

a < b or b < a is true

a < b is false

not (a < b) is true
