MATHS IN DAILY LIFE

Buying groceries:
comparing unit prices
estimating how much your total bill will be

Balancing your checkbook

Tracking your finances in general, especially if you invest your money (calculating interest)

Paying your taxes

Gambling (necessary if you want to be good at Texas hold-em)

Estimating how much paint you need to buy to paint a wall/house (you need to calculate areas, estimate coverage, etc. You will need math whenever you do house-stuff, like fixing up your basement, installing new insulation.

Time management (you only get 24 hours per day!)

Estimating how long it will take you to make a trip in a car (given average speed, distance to drive)

I could probably think of more examples, but I doubt any involve calculus.
