In reality there is no answer to the question: What is the highest number known to man? With the addition of 1, any number presented as the largest can be made obsolete. In the abstract, numbers stretch on to infinity with no end to how high they can go; however, the largest number that has a name in the English language is googleplex.
Know MoreGoogleplex is built on the number googol, which is 10^{100} or 10 followed by 100 zeroes. Googleplex is 1 followed by a googol of zeroes. However, this represents a naming convention only. Googleplex plus 1 is a still higher number.
The ongoing search for the highest prime number has produced figures in excess of a googleplex. The Mersenne Prime Project builds on the work of seventeenth century French scholar Marin Mersenne, who discovered a formula for calculating prime numbers. Before his time, the discovery of prime numbers came by chance and prime numbers that fall outside his formula are still slow to be discovered. Mersenne's formula — 2^{n}-1 — has been used to discover many new prime numbers. In 2013, a professor at the University of Central Missouri discovered the 48th Mersenne prime which is 2^{57,885,161}-1, a number with 17,425,170 digits.
Learn more about NumbersIntegers proceed upward in an infinite sequence, so no number can be said to be the "highest," as it is always possible to add one and get a higher number. Infinity is generally not regarded as a number but as a concept. The highest named number is the googolplex.
Full Answer >To divide by complex numbers, multiply by the conjugate, distribute to eliminate the parentheses, simplify, combine like terms, and represent the answer in standard form: a + bi. Remember that i^2 = (-1) when sorting out constants and imaginary terms.
Full Answer >The answer to 85 percent of 352 is 299.2. To find the percentage of a number, you first have to turn the percentage into a decimal. To do this, you take the percentage and move the decimal two places to the left.
Full Answer >The answer to a subtraction problem is called the "difference." The other two numbers in a subtraction equation are called the "minuend" and the "subtrahend." The minuend minus the subtrahend equals the difference.
