Basic Math: Scientific Notation. In this section, you will occasionally be asked to answer some questions.

These two ideas together are enough to require that we think of the universe as a 4-dimensional space-time in which the time between two events depends on who measures it, and whether two things happen at the same time depends on who's asking. We can most easily understand a sequence of events by using a space-time diagram. I'll use one space dimension instead of 3, because I can't draw 4-D diagrams. The diagram shows that there is a limited region of space that we can know about: the region that lies within our past light cone. When the light hits the mirror it corresponds to "tick" and when it return to the detector that corresponds to "tock". Now consider two sets of observers, one set remaining at rest with respect to the clock and another set moving at speed v, as shown in the diagram. The second observers see a moving clock, and notice that the light must travel a greater distance.

This free scientific notation calculator and converter can perform a range of operations in scientific notation, including adding, subtracting, multiplying, and dividing numbers. It can also convert real decimal numbers to scientific notation, and vice versa. To use the scientific notation calculator, simply input the numbers in scientific notation, select an operation, and click on the "Calculate" button to generate the output. Scientific notion, which is also referred to as "Standard Form" or "Exponential Form", represents a numerical value that is recorded in the following form:. It can readily characterize both very large and very small numbers.

Use this calculator to add, subtract, multiply and divide numbers in scientific notation, E notation or engineering notation. Answers are provided in three formats: scientific notation, E notation and engineering notation. You can also do operations on whole numbers, integers, and decimal numbers and get answers in scientific notation. If you mark the check box the calculator automatically determines the number of significant figures in the answer. If you do not mark the check box, answers may contain more digits than are signficant. Caution: See note regarding significant figures calculations. Use the links below to load a sample calculation into the calculator. In each example the input forms are different, but they all produce the same answers in scientific notation and E notation.

Since what you do to the exponent term undoes what you do to the coefficient, the total number does not change. Scientific notation was invented to help scientists and science students! Actually, they are only a little more complicated to write down than powers of ten. For each place you move it to the right, subtract 1 from the exponent. For each place you move the decimal place to the left, add 1 to the exponent. What you are doing is dividing or multiplying the coefficient by 10 each time, while at the same time multiplying or dividing the exponent term by 10 each time. Exactly on the boudary between these two kinds of universe is the flat universe which is not curved at all. If you are given a number in scientific notation to raise to a power, remember that all this means is that it is used as a factor that many times. The mass of 1 hydrogen nucleus is 1. The mass of 1 helium nucleus is 4.

Convert a number to and from scientific notation, e notation, engineering notation, standard form, and real numbers. Enter a number or a decimal number or scientific notation and the calculator converts to scientific notation, e notation, engineering notation, standard form and word form formats. You can also enter numbers in e notation.

The solution is that the universe underwent a dramatic change early on that caused a small region to expand rapidly. Scientific notation was invented to help scientists and science students! The second is the flatness problem: we don't know whether the universe is open or closed, but we do know that it is not very far from flat in either direction. If you are given a number in scientific notation to raise to a power, remember that all this means is that it is used as a factor that many times. This is analagous to the clearing of a fog, so that following this transition light could stream freely through the universe. If the number is expressed in words, first write it down as an ordinary decimal number and then convert. Since each helium nucleus has less mass than the 4 hydrogen nuclei that combine to form it, the mass difference is liberated as energy in the form of gamma rays. We live in this region which now appears both very uniform and very flat. Second, start moving the decimal point in the coefficient to the right or left. In situations where addition and subtraction are mixed with multiplication and division, do the multiplication and division first, then do the addition and subtraction. In his general theory of relativity, Einstein asserted that the fundamental reference frames for making measurements are those moving with objects that fall freely under the influence of gravity. The number is now in the standard form:. Your proper age is measured by your heartbeat: wherever you go.
