Use **events **or **values **for single input, or **values **for multiple inputs.

The following information describes this Function:

- This function is useful if you want to do some sort of mathematical expression on the input(s).
- If multiple inputs are used, it is advisable to use
**values-type**connections. - To make this function work, you must define the connection of the input tag(s) as a
**variable-name**(lets say “A”), and then use that in the mathematical expression, such as sin(A_value) or A_value*100. - If multiple inputs are needed, you must define each connection with a variable and use that in the expression. For example, “A_value + B_value”.
**Example**: (Celsius_value * 9/5) + 32 x_value +2 x_downtime *5
