No, the number 2 is the only even prime number. All other even numbers (4, 6, 8, etc.) are divisible by 2. (This is due to the definition of an even number as divisible by 2.) Thus, 2 is the only even number that can still be prime - the rest have at least one divisor other than 1 and themselves.

Some scientific calculators can't handle complex or imaginary numbers. If you happen to have a special calculator that does, probably the manual will tell you how to enter them.

The HP 48 and up series does. It depends on if your calculator is in Polar Coordinate mode or X-Y coordinate mode, but a quick way to get the imaginary number i (regardless of which mode the calculator is currently in), is to press -1, then 'square root' button.

Cubed means to take whatever number and multiply that number by itself three times. So 40 cubed means to take 40 times itself three times. Be very careful because it's not 40 times 3, which is a very common mistake! It's 40 times itself 3 times.

666 is the sum of the first 36 numbers: 1+2+3+4... + 36 = 666.

In the book of Revelation, it was most likely intended as a gematria reference; the sum of the numerals represented by hebrew letters in a name. Various candidates have been suggested throughout history.

For example, the hebrew letters of "Caesar Nero" would sum to 666. The roman numerals in "Ellen Gould White" add to 666 (interpreting W as VV and U as V). If you use the code A=101, B=102, etc, then "Hitler" will add up to 666.

Actually, if you can make up the rules as you go along, it's not hard to do with any name at all. Just pick a favorite bogeyman, say "Bill Gates", and try various codes. Aha! the ASCII values in "BILL GATES" (all caps) sum to 663, and then you can add 3 since he's really Bill Gates III.

It's been done with Martin Luther, Muhammad, Ronald Reagan, etc. If necessary, spell the name in Latin, or make up an official-sounding title and add up its roman numerals, and then find lots of subjective and cherry-picked evidence supporting why your target is the Beast of Revelation. For example:

The Roman numerals in the blasphemous title of the pope who claims to substitute for God, forgiving sins, etc., VICARIVS FILII DEI, V=5, I=1, C=100, L=50, D=500; add up to 666: 5+1+100+1+5+1+50+1+1+500 +1 = 666.

The first beast of Revelations 13 is an empire which had seven heads that persecuted God's people. First was Egypt where they were slaves to the pharaohs, second Assyria captured the 10 tribes of northern Israel, third Babylon captured the two remaining tribes of Judah, fourth Medo-Persia, fifth Greece (five are fallen, in John's time, and one is) sixth Rome destroyed the temple, seventh the papacy with the pope ruling from the fall of Rome until the deadly wound of 1798 when Napoleon captured the pope and confiscated all the papal lands. Italy's Benito Mussolini healed the wound, restoring the Vatican City by the Lateran Treaty in 1929. The seventh, restored, became the eighth.

In 1776 a country rose to power on another continent, creating a religious system derived from the Protestant daughters of the great whore, keeping the traditions of man above the commandments of God, trading Passover for Easter, Sabbath worship for "sun"day worship, etc. These were sanctified by the pope, not by the apostles; they are not mentioned in the Bible. Receive the mark of the beast by obeying the pope's laws while disobeying God's laws.

Percentages, Fractions, and Decimal Values

To convert a fraction to a percent, you first divide the numerator by the denominator. And then multiply by 100, which moves your decimal point two places to the right.

Another way to do it, or check your answer, is to make the fraction equivalent to a denominator of 100. So if you were to convert 8/25 to X/100, your new numerator would be the percentage.

32+42=52

9+16=25

You can keep this pattern going, too:

3² + 4² = 5²

6² + 8² = 10²

9² + 12² = 15²

12² + 16² = 20²

And so on and so forth...

Yes, the bar over the 2, means that the digit (or digits) are repeated forever.

so 0.2 (with bar over 2) = 0.2222222222..... is decimal for 2/9 (fraction)

and 0.2 (no bar) = 0.200000000 which is 2/10

you could look at it a few ways.

0.2222222.... = 0.2 + 0.0222222.... which is greater than 0.2

or compare 2/9 & 2/10, 2/9 = 20/90 & 2/10 = 18/90

with the same denominator 20 > 18, so 2/9 > 2/10
