The standard basic math operators are available, and you can also use Math Functions for more complex operations.
10 + 2 // 10 plus 2 = 12
10 - 2 // 10 minus 2 = 8
10 * 2 // 10 times 2 = 20
10 / 2 // 10 divided by 2 = 5
10 % 2 // 10 mod 2 = 0
10 < 2 // 10 less than 2 = false
10 > 2 // 10 greater than 2 = true
10 <= 2 // 10 less than or equal to 2 = false
10 >= 2 // 10 greater than or equal to 2 = true
10 != 2 // 10 not equal to 2 = true
10 = 2 // 10 equal to 2 = false
