In the third grade, compatible numbers are estimated figures that are used to make mental arithmetic simpler. Compatible numbers are very close to the actual numbers and yield a similar result with less work.
A:The prime numbers less than 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97. A prime number is any number that is only divisible by itself and 1. The number 1 is not considered a prime number.
A:A landmark number is a number that makes math simpler by virtue of it being easy to relate to and calculate with, such as the number "10." Most landmark numbers are multiples of 10.
A:The Mayan number system is a base-twenty system that was developed by the Mayan civilization around the fourth century A.D. Only three symbols are used to represent all numeric values: a shell for zero, a bar for five and a dot for one. These symbols are arranged in columns that are read from top to bottom, and the columns are arranged in powers of 20.
A:Pi is a real number, as all numbers that exist on a number line are real. Real numbers include all rational and irrational numbers; pi is defined as an irrational number.
A:A non-real, or imaginary, number is any number that, when multiplied by itself, produces a negative number. Mathematicians use the letter "i" to symbolize the square root of -1. An imaginary number is any real number multiplied by i. For example, 5i is imaginary; the square of 5i is -25.
A:A distance of 500 meters is the same as a distance of 0.31 miles. The one-step conversion of meters to miles is found by multiplying the number of meters by 0.00062137.
A:Zillion has an indeterminate number of zeroes. Despite the popular misconception, zillion actually is not a true number. Rather, zillion is defined as an indeterminately large number.
A:A linear pattern exists if the points that make it up form a straight line. In mathematics, a linear pattern has the same difference between terms. The patterns replicate on either side of a straight line.
A:A Roman numerals list includes Hindu-Arabic numerals with a corresponding set of symbols. The letters I, V, X, L, C, D and M are used as symbols by Romans in a unique system of representing numbers.
A:According to Joy of Pi, the value of pi to 100 decimal places is expressed as 3.1415926535897932384626433832795028841971693993751058209749445923078 164062862089986280348253421170679. Pi is an irrational number with a limitless, non-repeating decimal expansion.
A:Every integer is not a whole number, but every whole number is an integer. An integer is any number, positive, negative or zero, that is able to be represented without a fraction or decimal, according to Reference.com. The number of possible integers is infinite.
A:A number is a theoretical concept, and a numeral is the way that people denote that concept. A numeral contains one or more written symbols, but a number can be expressed in a range of ways. Number and numeral are often used interchangeably, but there is a slight difference between them.
A:Standard notation is when a number is completely written out using numerical digits. Some examples of numbers written in standard notation are 64,100 and 2,000,000.
A:A whole number belongs to the set of integers that are equal to or greater than zero. For example, the set of numbers {0, 1, 2, 3, 4, 5, ...} contains all of the whole numbers.
A:Compatible numbers are simple or simply added numbers with close values to more difficult numbers, substituted in their place for ease of calculation. An example would be substituting 15 and 3 when trying to multiply 14.8 and 2.6.
A:Multiples of 17 are numbers by which 17 can be exactly divided, such as 34 or 51. A multiple of 17 is any number that is a product of 17 and an integer.
A:Some basic mathematical symbols include + (addition sign), - (subtraction sign), x (multiplication sign), ÷ (division sign) and π (pi). A few more complex symbols are ∞ (infinity), |x| (absolute value), sin (sine), cos (cosine) and tan (tangent).
A:It is widely believed by historians that Leonardo Fibonacci was never married. While little is known about his personal life, there is no record of a wife or children.
A:A googol has 100 zeroes in expanded notation, and in exponent notation, it is 10 to the power. A googol is written by writing the digit one and then putting 100 zeroes after it.
