## 4. Operator Modules

The modules in the "Operators" category represent standard mathematical operators.
### Add

This module outputs the sum of its two inputs.
### Subtract

This module outputs its first input minus its second input.
### Multiply

This module outputs the product of its two inputs.
### Divide

This module outputs its first input divided by its second input.
### Power

This module outputs its first input raised to the power of its second input. More
accurately, its output is given by:
`
`

y(x) = | x^{p} | if x>0 |

| -x^{-p} | if x<0 |

where x and p are the two inputs.

### Mod

This module calculates its output value according to:
`
y(x) = x Mod M
`

where the input value x and modulus M correspond to the two input ports.

### Greater Than

This module has two input ports. Its output is equal to 1 if the first input value is
greater than the second one, and zero otherwise.
You might wonder why there is a "greater than" module, but not a "less than" module. Hint:
Try reversing the inputs.

### Min

This module outputs the minimum of its two inputs.
### Max

This module outputs the maximum of its two inputs.
