What is 847 in engineering notation?
Engineers tend to use the most appropriate notation for a given situation, and in many situations, 847 will be a perfectly fine way of expressing the number 847 for an engineer.The expected answer to this question most probably is 0.847E3 though, which indicates a base number (0.847) is to be multiplied by 10 to the power of 3 (103=1000), thus 0.845E3 = 0.847 * 103 = 847.Engineering notation becomes more appealing with much larger numbers, or numbers much smaller than one (regardless of the number's sign). As a rule of thumb, you should consider using engineering notation for numbers that make you squint and count the zeroes. Straight-forward numbers such as 847 do not benefit from such complication. Engineers are pragmatic people.

What is engineering notation?
Scientific notation is a way to "easily" or "conveniently" write very large or very small numbers. As these numbers are frequently encountered in the sciences, the term scientific notation was introduced to name this "neat" way to "package" these quantities so that they might be more easily grasped and understood.Scientific notation is a useful way of dealing with very large and very small numbers. It allows them to be presented in a form where their magnitude can be seen more easily. Also it can simplify calculations by allowing you to concentrate on the significant digits rather than the orders of magnitude which are very easily dealt with. This latter advantage has somewhat diminished with the widespread availability of calculators and computers. But previously, people used log tables and slide rules for multiplication and division. These calculating devices depended on thinking of numbers in their scientific notation and utilizing the significant digits.The Form of Scientific NotationThe idea behind scientific notation is to write numbers in terms of powers of ten - either positive (for very large numbers), or negative (for very small ones). As an example, consider the mass of an electron, which is approximately 0.0000000000000000000000000001 grams. An easier way to write it uses the significant digit 1 and an exponent based on a multiple of ten. The number becomes the easily represented 1 x 10-28 g.The simple rule is to take your "numbers" and move the decimal point to the left or right so that only one figure is to the left of the decimal. Then write the rest of the significant digits to the right of the decimal, and tack on the appropriate power of ten (again, either positive or negative) to restore the proper value to the figure.Coefficient and Base in Scientific NotationScientific Notation also avoids the headache and potential errors of counting lots of zeros.The number 123000000 in scientific notation is written as:1.23 x 108The first number 1.23 is called the coefficient. It is always a single digit followed by a decimal point and then the rest, but usually only two digits.The second number is called the base and in scientific notation must always be 10. In the number 1.23 x 108 the number 8 is the exponent or power of ten.How to Write a Number in Scientific NotationFor large numbers :1) Put the decimal after the first digit and drop the zeroes. In the number 123,000,000 the coefficient will be 1.232) Then write the times "x" and the base 10.3) To find the exponent count the number of places from the "new" decimal point to the end of the number. In 123000000 there are 8 places. Therefore the exponent is 8.There are some minor variations that have evolved to fill different needs, usually because not all fonts or printers allow superscripts: 123000000 can be written as:1.23 E+11 or 1.23 X 10^11 or 1.23 x 1011For small numbers :For numbers less than one we use a similar approach. These numbers all have negative exponents. For example 0.00000123 second (1.23 microseconds) is written:1.23 E-6 or 1.23 x 10^-6 or 1.23 x 10-6Take the original number 0.00000123 and shift the decimal point to the right until you get the coefficient in proper form, as above. The number of digits shifted is then the negative exponent.Notes:a) Numbers less than one all use negative exponents, but what about negative numbers, such as -0.04? We can write this as-4.0 x 10-2b) Always make sure the E is capitalized in 1.23 E-6, otherwise it can be confused with "e" the base of the natural log system.c) Some scientific and engineering fields have special rules, such as electronics where scientific notation is usually in powers divisible by three, such as -3, 3, 6, 9, 12, etc. This is because electronic components are made using standard SI prefixes such as kilo, micro, nano, or pico.d) Usually, Scientific Notation is ignored if you want to keep numbers in common formats, such as 315 microseconds, instead of 3.15 x 10-4 seconds, but this is a matter of preference.Scientific notation is normally used for numbers that are either far to large or far to small to be written conveniently in decimal notation.A,BFor example the Earth's mass is approximately: 5,973,600,000,000,000,000,000,000.0 kgIn scientific notation this would be written as:5.9736 x 1024 kg.In normalised scientific notation numbers are written in the form:A,Ba x 10nWhere:a is a number between 1 and 10n is a positive or negative whole number.In engineering notation, the n value is commonly in the form of multiples of 3. In this way the number will always explicitly match the corresponding SI prefixes.BFor example a distance of 50,000 m would be written as:Scientific Notation: 5 x 104 mEngineering notation: 50 x 103 mIn this example 103 corresponds to the SI prefix "kilo"C as such the engineering notation could be directly described verbally as "fifty kilometres" whereas scientific notation yields the much more unwieldy "five times ten to the power four metres" which is much less intuitively easy to understand, even though it is exactly the same distance.Guidance on converting to and from scientific notation is given in the related links.

The oldest branch of engineering?
The term engineering is derived from the word engineer, which itself dates back to 1325, when an engine'er (literally, one who operates an engine) originally referred to "a constructor of military engines." In this context, now obsolete, an "engine" referred to a military machine, i. e., a mechanical contraption used in war (for example, a catapult). Later, as the design of civilian structures such as bridges and buildings matured as a technical discipline, the term civil engineering entered the lexicon as a way to distinguish between those specializing in the construction of such non-military projects and those involved in the older discipline. As the prevalence of civil engineering outstripped engineering in a military context and the number of disciplines expanded, the original military meaning of the word "engineering" is now largely obsolete. In its place, the term "military engineering" has come to be used. so generally we can say that military ,categrized initially both as civil and mechanical engineering is the oldest among all the enginnering branches nowdays..

Can a negative number be expressed in scientific notation?
Yes, a negative number can be expressed in scientific notation. In scientific notation, a negative number is indicated by the negative sign (-) placed before the first significant digit. The number is then written in the form of a decimal number between 1 and 10, multiplied by a power of 10. For example, -3.2 x 10^-5 is a negative number expressed in scientific notation.

What is 3300000 in scientific notation?
Just slide the decimal point over until you have moved it some multiple of three times (3, 6, 9, 12) but without causing 0s to be the only thing left of the decimal point. 3300000 would be best expressed moving the decimal point to the left 6 places. This would give us 3.3 but we need to incorporate the notation that we have moved the decimal place. Because we moved it to the left, we must show that the actual number is bigger than 3.3 so the exponent is positive. We moved it exactly 6 places so the final answer is 3.3x106
