The four fundamental operation have no intrinsic value. As the name suggests, they are operators. In fact, they are binary operators, which means that they take two values as input and their output is a single value. That value will depend on the inputs.

Lemma 2 says that if the curved area is approximated by inscribed and also by exscribed rectangles, where all rectanlges are of equal width, then the ratio of the exscribed areas summed up, to the curved area will be 1 as the number of rectangles tends to infinity. Also, the ratio of the sum of the area of the inscribed rectangles to the curved area to the curved area will be equal to 1 as the number of rectangles tends to infinity. In less technical language, the rectangles approximate the area under the curve, and as we use more and more (and thus thinner and thinner) rectangles, the approximation will get better and better; in fact we can make it as accurate as we want to. Lemma 3 says the same as the above, but drops the requirement that the rectangles all be of equal width.

The first mechanical counting device was invented by Blaise Pascal in 1642. It was primarily used as an adding machine. It could add and subtract two numbers.

Hey!

I just laid down a laminate floor. The planks were sold in packs of 8 and covered a certain square area. I had to measure my room and work out what the total area was and how many packs I needed, allowing 1 extra pack for offcuts.

When I finished I only had a few planks left in one pack, just as I had calculated.

I could not have done that if I didn't understand maths. I could either guess or:-

I would have to call someone in (at extra expense)

I would have had to keep going to the depot, to get more timber and run the chance they would sell out, or change the color.

I would be left with too many packs left over and live with the waste or take them back. (extra journey, time, waste.)

You need maths in most aspects of modern living, without it you will get ripped off or left confused. Do try to learn and do the best you can.

Hipparchus is the father of trigonometry.

nothing.

The formula for a perimeter (not rpimeter) is the sum of all the boundaries of the shape.

The first civilization to use the concept of zero is the Toltec tribe of Mesoamerica.

Pythagoras

First you have many different numbers.

Then you make a list down such as O | 7 meaning its 7, or 2 | 9 meaning its 29.

You set these all in order from 0- the last number you have.
