Numbers

Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

Are there any even prime numbers other than two?

User Avatar
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.

How do you enter an imaginary number in a scientific calculator?

User Avatar
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.

How do you write 60 million in number form?

Something that is a million starts on the left of 6 digits before the decimal point. For instance, 1 million is 1,000,000.0. Then, 60 million in number form is: 60,000,000

What numbers add up to make 666?

User Avatar
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.

What is 40 cubed?

User Avatar
To cube a number means simply to multiply that number by itself 3 times. To work out 40 cubed you would simply go: 403 = 40 x 40 x 40 40 x 40 = 1,600 1,600 x 40 = 64,000 403=64,000 Therefore, 40 cubed equals 64,000. The phrase "multiply that number by itself 3 times." can cause confusion. Sometimes, instead of multiplying it thrice (the number itself) others, due to confusion, just multiply the number by 3... take note it's cube... What do you get if you multiply 40 by itself once? Nearly everyone would say 1,600 which is 40². Multiply that by 40 then seems to mean multiply the answer by 40, giving 64,000 which is then 40 multiplied by itself twice! Of course some people will say it doesn't matter how many times you multiply 40 by itself you'll always get 1,600. Just think of 40³ as meaning 3 40s multiplied together and you should avoid any problems.

Is 0.2 with a horizontal line over it greater than 0.2 without the line?

User Avatar
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

What is a decimal of 140 percent?

User Avatar
The percent sign % can be defined as "divide by 100". So the decimal of 140% would be 140/100 or 1.4 So if you wanted to know what 140% of any number was you could multiply by 1.4 i.e. 140% of 50 is 50 x 1.4 = 70, or since multiplication is distributive you could also do this (140 x 50)/100 which will also give you 70 1.4

When the lesser of two consecutive integers is added to three times the greater the result is 43 Find the integers?

User Avatar
Let the two integers be m-1 & m, so the lesser integer is m-1, and the greater integer is m: (m-1) + 3*m = 43 --> 4*m -1 = 43 --> 4*m = 44, m = 11 & m-1 = 10, so 10 & 11 Check: 11 times 3 is 33, add 10 is 43

Is 55 an even number?

User Avatar
no because a full number would be divisible by 2, in this case it is not. Hints: If the final digit is odd the full number is odd. If it is even or 0, the whole number is divisible by 2: if 0 the answer will end in 5.

What does the word product mean in math?

User Avatar
When you multiply, your answer is called a product. In math, the word "product" implies multiplication. If you are asked to find the product of two numbers, you should multiply them together. So the product of 3 and 4 would be 3*4=12 Product is the answer you get when you multiply Example:2×6=12,so 12 is the product
