## Syntax

## How to use

The IMSUB function gets the difference between two complex numbers in the form x + yi or x + yj. For example:

```
=IMSUB("1+2i",3) // returns "-2+2i"
=IMSUB("3+4i","1+2i") // returns "4i"
```

In the example shown, the formula in D6, copied down, is:

```
=IMSUB(B6,C6)
```
