Scientific notation is choose shorthand for composing very large or very little numbers. Instead of creating the number in decimal form, the number is shortened to a number multiplied by a strength of ten.

Mathematical Shorthand

In scientific notation:

The first number in the mathematics equation is called the "coefficient." The coefficient must be higher than or same to one and also less than 10. For example to develop the scientific notation for the number 256, the coefficient would certainly be 2.56.The second number in the equation is a power of 10, created as 10 v an exponent, choose 102 which stands for 10 x 10.

Combining these 2 numbers would develop this scientific notation equation because that 256 - 2.56 x 102.

A an adverse exponent shows the decimal is moved that many places to the left and also a positive exponent shows the decimal is moved that plenty of places come the right.

Multiply (4 x 104) and (7 x 105)First 4 x 7 = 28Next add exponents, 4 + 5 = 9Result is 28 x 109Rewrite in conventional form, 2.8 x 1010Divide (6 x 105) through (4 x 104)6/4 = 1.5Subtract exponents 5 - 4 = 1Answer 1.5 x 101 or 15Multiply (4 x 10-7) and also (3.25 x 109)4 x 3.25 = 13Add exponents = -7 + 9 = 2Answer is 13 x 102 or 1300

Adding and also subtraction needs that the exponents be the same, so part manipulation is needed:
