Hello, today I will talk about the civil war lets get into it,the civil war begin in April 12,1861 - May 9, 1865, The American Civil War was a civil war in the United States fought between the Union and the Confederacy.

On the eve of the civil war in 1860, four million of the 32 million Americans were enslaved black people, almost all in the South.

Science

Science, hello and today I will talk about the solar system, The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly—the natural satellites—two are larger than the smallest planet, Mercury, and one more almost equals it in size.

Math

Math, today I will talk about the Sientific Notation, Scientific notation is a way of expressing numbers that are too large or too small (usually would result in a long string of digits) to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard form in the UK. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations. On scientific calculators it is usually known as "SCI" display mode.
