# Keeping zeros after matrix multiplication

Hello, Sage Community!

Suppose I do the following:

```
var('x y z')
u = vector([0, 1, 1])
v = vector([x, y, z])
u * v
```

The result is obviously `y+z`

. I would like to keep the zeros after the multiplication, in order to have `0x+y+z`

as my result. Is it possible?

Thanks in advance for your answers!
