I could go a few days without using maths at work but rarely a week.
The amount of maths I use varies based on the timeline of where I am in a project, there is alot more maths during the design and implementation stages, as I work things out, than during the test stages.
But I also use maths to work out my hours every week. I have flexible hours so I can work shorter hours Monday and Tuesday but then I have to work out where I can work longer hours for the rest of the week while also making sure I take enough time off for lunch/breaks.
