Math is hard.

Yesterday, I provided you all with examples of why english is hard to master.

Today, I am going to tell you about why people don't know how to do math anymore. And, to do that, I am going to demonstrate how math has changed through out the decades.

I fall into the 1970's category.

In the **1950's**:

A logger sells a truckload of lumber for $100. His cost of production is four-fiths of the price. What is his profit?

In the **1970's**:

A logger exchanges a set, L, of lumber for a set, M, of money. The cardinality of set M is 100, and each element is worth $1, Make 100 dots representing the elelments of the set M. The costs of production, set C, contains 20 fewer points than set M. Represent Set C as a subset of M, and answer the following question: What is the cadinality of the profits, Set P?

As you can see by the progression of the way we teach kids math, it should be no surprise that people today can't do basic math without their phone or computer. If we are to survive as a civilization, we need to ensure people learn how to do things without technology. One solar flare could wipe out every piece of electronics on the planet, and utterly wipe out the power grid.

How long could you survive with the skills you know? And, I'm not talking about hunting or whatnot. There are people who know how to do that that will barter their food for whatever skill you posses. But, if you don't know basic math, you're screwed.

So, teach your kids how to do math without depending on a tool.

I'm not the original author of these examples. I would like to tell you who is, but honestly, I don't know. This is something I saw a long time ago. When I went to research it, the 2000's had been added.
