What 1G or 2G?

In 80s, the first 1G device (the first-generation of wireless telephone technology) came out. It was called the mobile phone made by Dr Martin Cooper.

OK, it a smartphone but it better that a answering machine

Today, have lots of 2G network. By 1985 the was only Motorola DynaTAC, Nordic Mobile Telephone and Vodafone for the UK.

10 year later after the first 'wireless telephone'. 2G come out.

In 90s for the first time,you can go on the World Wide Web with out wire from a telephone line

It uses a Router connect to telephone. The Router sends signal to area around.

This was amazing. Most people use 2G today. The UK average is 6.2Mbps

After the New Year, I will do a post on 3G and 4G

Facebook is NOT your future !! Google+ is!!

It seems hard to even believe that on 15 March,Mark Zuckerberg is going to give up and shut down Facebook

The story was first reported by the Weekly World News, which has been in the past responsible for stories like "Alien Spaceships to Attack Earth in 2011", "Megan Fox is a man" and "George Clooney to Run or President".

No-one believe in Facebook closing down until Mark Zuckerberg said it to the BBC.

MySpace,Twitter or Google+ (Google Plus). Google+ is the best,will you being missing Facebook...

Equation Calculator & Solver

Quick-Start Guide

When you enter an equation into the calculator, the calculator will begin by expanding (simplifying) the problem. Then it will attempt to solve the equation by using one or more of the following: addition, subtraction, division, taking the square root of each side, factoring, and completing the square.

Variables

Any lowercase letter may be used as a variable.

Exponents

Exponents are supported on variables using the ^ (caret) symbol. For example, to express x², enter x^2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses.

Parentheses and Brackets

Parentheses ( ) and brackets [ ] may be used to group terms as in a standard equation or expression.

Multiplication, Addition, and Subtraction

For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessiary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x - 1).

Order of Operations

The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error.
