Add space between 2 columns in calculated column

Hi,

I am trying to create a calender view for my sharepoint list where the text shown for each list item is a combination of 2 or more columns in the calender view.

I have created a calculated column like this 

=Title&Score&Assigned 

This combines the text, number and choice from the 3 columns, however i would like to add a space inbetween each column to the final display is like this

Title Score Assigned

Instead of 

TitleScoreAssigned

How can i achieve this?

Thanks in advance
