VALUE1
-
VALUE2
The - operator subtracts the numeric value on the right from the numeric value on the left.
Parameters
This operator has two parameters:
value1 – The first numeric value.
value2 – The second numeric value.
Description
This operator performs subtraction just like you learned in grade school. You can subtract integers:
5-2 ☞ 3
And you can also subtract floating point values:
5.75-2.5 ☞ 3.25
Error Messages
Cannot subtract a number from text (or text from a number) – Both operands must be numbers. If either or both operands are text values you must use the val( function to convert the value to a number before subtracting.

- * -- multiplies the numeric value on the left by the numeric value on the right.
- / -- divides one numeric value by another.
- \ -- performs integer division.
- ^ -- raises a number to a power.
- + -- works differently depending on the type of operands used with it.
If both operands are numeric, it does numerical addition.
If either operand is text the + operator concatenates (joins together) the two operands.
