They are all three digit numbers between 200 and 699.
The first digit can be one of 2, 3, 4, 5, 6, a selection of 5.
The second digit can be any of the ten digits (0-9) that have not been already picked, namely one of a selection of the remaining 9.
The third digit can be any of the ten digits than have not yet been picked, namely one of a selection of the remaining 8.
So there are 5 x 9 x 8 = 360 numbers with no repeated digits between 200 and 699.
There are 90 positive numbers with two digits. This is because the range of two-digit numbers is from 10 to 99 (inclusive), and there are 90 numbers within this range.
Individual digits within a number have place values, not whole numbers.
The concept of place value is relevant only for digits within a number, not for entire numbers. The question, therefore, makes no sense.
There are none between 2 and 3.2 & 3 are both prime numbers though.
None.
The number is: 36725918 In descending order that is: 98765321 The pairs of numbers that have as many digits between them in both are: 3,9 5,8 6,7 So there are three pairs.
There are 90 positive numbers with two digits. This is because the range of two-digit numbers is from 10 to 99 (inclusive), and there are 90 numbers within this range.
Individual digits within a number have place values, not whole numbers.
There are 90 numbers within the range specified, that adhere to your rule.
No! The number of digits varies by country, and may vary within a country. International standards restrict the total phone number length including country code to 15 digits maximum (which would be 11 digits for the US and Canada including our country code +1), but what happens after the country code is up to that country. 10-digit and 9-digit phone numbers within a country are common. Smaller countries may have fewer digits: Iceland has 7-digit numbers. China uses 10 digits for landlines but 11 digits for mobile phones; it is effectively in a slow migration to 11 digits. Germany until a few years ago had variable length numbers from 7 to 12 digits, the subscriber (local) part being as short as 4 digits for old numbers and longer for new numbers, but since 2010 uses 10 or 11 digits total. Most countries use 2-digit area codes (with 7 or 8-digit local subscriber numbers), but that varies too, with some using 3 or 4-digit area codes. The UK uses a variable length area code: Even though UK phone numbers are 10 digits almost everywhere (9 digits for certain old numbers), the city code portion can be from 2 to 6 digits, so that large cities have a 2-digit city code and 8-digit local portion, while smaller towns have longer city codes and shorter local numbers.
there are 9 digits in the SSN The digits in the Social Security number allow for the orderly assignment of numbers. The number is divided into three parts: the area, group and serial numbers. The first three (3) digits (area) of a person's social security number are determined by the ZIP Code of the mailing address shown on the application for a social security number. Within each area, the group number (middle two (2) digits) range from 01 to 99 but are not assigned in consecutive order. For administrative reasons, group numbers issued first consist of the ODD numbers from 01 through 09 and then EVEN numbers from 10 through 98, within each area number allocated to a State. After all numbers in group 98 of a particular area have been issued, the EVEN Groups 02 through 08 are used, followed by ODD Groups 11 through 99. Within each group, the serial numbers (last four (4) digits) run consecutively from 0001 through 9999.
The concept of place value is relevant only for digits within a number, not for entire numbers. The question, therefore, makes no sense.
Not unless the larger section is repeated using D.C./D.S. markings.
There are none between 2 and 3.2 & 3 are both prime numbers though.
A Pakistani mobile number looks like +92 3XZ YYY YYYY. That's a total of 12 digits, including the country code, or 10 digits for the national significant number. Within Pakistan, you dial the trunk prefix 0 followed by the 10-digit number, for a total of 11 digits.
Quite a few countries now have 8-digit telephone numbers, in at least some part(s) of the country. Some countries, like Australia, have 8-digit local numbers throughout the country, from the largest city to the smallest village. Other countries, like the UK, have 8-digit local numbers only in certain areas, with local numbers as short as 5 digits in some other areas. Quite a few countries, including Norway and Denmark, have 8-digit or longer national telephone numbers, but you must dial the entire national number, even on local calls.Here is a partial list:Eight-digit local numbers in all areas:Australia (four area codes, each with 8-digit local numbers)Brazil (local numbers are 8 or 9 digits)ChileEight-digit local numbers in some areas:UK (London, Northern Ireland, and certain other areas)Germany (Berlin, Hamburg, Munich, Frankfurt)Mexico (Mexico City, Guadalajara, Monterrey)Japan (Tokyo and Osaka areas only)People's Republic of China (all major cities)India (major metropolitan areas)Pakistan (Karachi and Lahore)Indonesia (major cities)Iran (Tehran, Alborz, and Qom)South Korea (Seoul)Malaysia (Kuala Lumpur, Putrujaya, Selangor)Vietnam (Hanoi and Ho Chi Minh City)Taiwan/Republic of China (Taipei and Taichung)Slovakia (Bratislava)Sweden (Stockholm)Argentina (Buenos Aires)ParaguayEgypt (Cairo, Alexandria)Ten-digit local numbers in some areas:Canada (AB, BC, MB, QC, SK, most of ON, soon NS & PE)USA (all "overlay" areas)Russia (Moscow)Eight-digit (or longer) nationwide numbers:DenmarkNorwaySpain (9 digits)Portugal (9 digits)France (10 digits), including some overseas départements and territories GuadeloupeMartiniqueSaint-Barthélemy ("Saint Barts")Saint-Martin (French part)St. Pierre & MiquelonRéunionMayotteItaly (10 digits), including countries that share the Italian phone system San Marino (all landline numbers begin with 0549)Vatican City (all landline numbers begin with 06698)Czech Republic (9 digits)Belgium (9 or 10 digits)Greece (10 digits)Switzerland (10 digits)Dominican Republic (10 digits)BahrainBurkina FasoRepublic of Congo (Brazzaville)BeninBurundiAngola (9 digits)LatviaKuwaitNepalOmanQatarSingaporeMacauAlbaniaLuxembourgMaltaMonacoCosta RicaGuatemalaHaitiHondurasNicaraguaUruguayBurkina FasoCameroonCentral African RepublicChadDjiboutiEquatorial Guinea (9 digits)Ghana (10 digits)Côte d'Ivoire (Ivory Coast)LesothoMaliMauritaniaMorocco (10 digits)Mozambique (8 or 9 digits)NigerRwanda (mostly 9 digits, some 8 digits)SwazilandTanzania (10 digits)TogoNational numbers up to 8 digits in some cases:Estonia (landline numbers are 7 digits, mobiles are 7 or 8 digits)Hong Kong (7 or 8 digits)El Salvador (7 or 8 digits)Panama (7 or 8 digits)French Polynesia (6 or 8 digits)Bhutan (mobile numbers are 8 digits)Botswana (mobile numbers are 8 digits, landlines are 7 digits)Liberia (7, 8, or 9 digits)Malawi (7 or 9 digits)Mauritius (up to 8 digits)Note: the digit length shown above is as dialed domestically within each country.

8(6741)3= 8(7654)3 the digits between 8,3 are 4. 6(7)4=6(5)4 so the answer is four (8,3&6,4)
