I couldn't agree more. Maths is important for Accounting because of the logic skills which are taught in Mathematics. Accountants disclose information pertaining to past events which have occurred during the business' financial year.
Many students pursue a career in Accounting and many tend to change their plan as Accounting is very concerned with what had happened, last quarter/ last year rather than emphasising future plans.
The Management Accounting area tends to be more "forward-looking" as it relies on data/information to make informed decisions to try create/improve something in the future.
I agree with your point about Cash Flow, its the single most important factor that businesses need to consider it they want to be sustainable longer term. Wonderful post with great nuggets of wisdom :)
