Why do we need to learn math if we aren't going to use math in our lives?

I'll challenge you to describe a life that doesn't use math.
I'll even bet you money that you can't do it.

Even if you move to a remote Pacific island, where only two
or three other people live, wear banana leaves for a skirt, and
hunt, trap, fish, and pick fruit for food, you can't do it.

The first time you catch 200 fish and your neighbor picks
150 coconuts, you need some coconuts and he needs some fish,
so you decide to trade some of yours for some of his. You both
need to agree on how many coconuts are worth how many fish,
and how long the fish will stay edible before they begin to stink. 
Then you need to know how to count fish, coconuts, and days.
None of that can happen without some math.

I promise you ... The only way you're going to live a life without math
is if you decide right now that you refuse to learn any, and you grow up
not knowing any.  Then you'll be lucky to get a job, and if you do then
you'll never know if you're getting paid the right amount or being cheated. 
You'll never know what you can buy and what you can't, and you'll go
through life totally broke. 
You'll wake up one day and say to yourself "Self ! How can you call this a life ? ! ?"

I'm not sure exactly but my best guess would be 1/4
