what does the E mean in a calculator's answer?
The "E" in a calculator's answer usually represents scientific notation or exponential notation. It indicates that the number is written in a compact form, where the "E" represents "times 10 raised to the power of." For example, if a calculator displays "2.5E+6," it means 2.5 multiplied by 10 raised to the power of 6, equalling 2,500,000. Similarly, if it displays "3E-4," it means 3 multiplied by 10 raised to the power of -4, equalling 0.0003.
The "E" in a calculator's answer represents scientific notation or exponential notation. It is used to denote large or small numbers that are expressed as a number multiplied by a power of 10.
For example, if a calculator displays 3.2E+5, it means 3.2 multiplied by 10 raised to the power of 5, which is equivalent to 320,000. Similarly, If a calculator displays 4.5E-3, it means 4.5 multiplied by 10 raised to the power of -3, which is equivalent to 0.0045.
In scientific notation, the "E" followed by a positive or negative exponent indicates how many places the decimal point needs to be moved to specify the number precisely.
The "E" in a calculator's answer, often seen in scientific or engineering calculations, represents "exponent" or "power of ten" notation. This notation is used to express very large or very small numbers in a more compact form.
For example, if you see "2.5E+4" on a calculator display, it means 2.5 multiplied by 10 raised to the power of 4, which is equal to 25,000. Conversely, "3.2E-3" would represent 3.2 multiplied by 10 raised to the power of -3, which is equal to 0.0032.
To calculate with numbers expressed in this scientific notation, you need to follow a simple rule. In "aEb" format, the value "a" multiplied by 10 raised to the power of "b" gives you the final result. Positive "b" indicates a large positive value, and negative "b" indicates a small decimal fraction.
For instance, if you have "5.2E+2," it means 5.2 multiplied by 10 raised to the power of 2, which equals 520. On the other hand, "1.6E-4" represents 1.6 multiplied by 10 raised to the power of -4, which equals 0.00016.
