# Arithmetic Aggregation Operators¶

Arithmetic expressions perform mathematic operations on numbers. Some arithmetic expressions can also support date arithmetic.

Name Description
\$abs Returns the absolute value of a number.
\$add Adds numbers to return the sum, or adds numbers and a date to return a new date. If adding numbers and a date, treats the numbers as milliseconds. Accepts any number of argument expressions, but at most, one expression can resolve to a date.
\$ceil Returns the smallest integer greater than or equal to the specified number.
\$divide Returns the result of dividing the first number by the second. Accepts two argument expressions.
\$exp Raises e to the specified exponent.
\$floor Returns the largest integer less than or equal to the specified number.
\$ln Calculates the natural log of a number.
\$log Calculates the log of a number in the specified base.
\$log10 Calculates the log base 10 of a number.
\$mod Returns the remainder of the first number divided by the second. Accepts two argument expressions.
\$multiply Multiplies numbers to return the product. Accepts any number of argument expressions.
\$pow Raises a number to the specified exponent.
\$sqrt Calculates the square root.
\$subtract Returns the result of subtracting the second value from the first. If the two values are numbers, return the difference. If the two values are dates, return the difference in milliseconds. If the two values are a date and a number in milliseconds, return the resulting date. Accepts two argument expressions. If the two values are a date and a number, specify the date argument first as it is not meaningful to subtract a date from a number.
\$trunc Truncates a number to its integer.
