to do it the long way do it by long division to do it the short way put it in the calculator 2 digits numbers are just the numbers between10-99 and one digits numbers are just the numbers between 0-9.
A positive number is greater than a negative number. If a positive number is greater than another, the corresponding negative numbers are smaller. For example, since 4 > 3, -4 < -3. For two positive numbers: The number with more digits is greater. If they have the same number of digits, the number with the greater first digit is greater. If they are equal, look at the second digit, which will decide which number is greater, and so forth, up to the last digit. For example, 12500 is greater than 12480: they have the same number of digits, the first two digits are the same, but the third digit is the tie-breaker. For numbers with decimals, first apply the rules above for the whole part. If they are equal, check the first digit after the decimal point, then the second, etc., until you find a "tie-breaker". For example, 0.2522 is more than 0.2517. Once again, the first two digits are the same, the third is the tiebreaker.
If x - y > 0, then x is greater than y.The greater positive number is the one further from zero.Which number is greater can be worked out on a digit by digit basis:To compare numbers starting with the highest place value column compare the digits, moving right a place value column until either all digits have been considered or one digit is higher than the other - the number with the higher digit is the greater number. (If a place value column is empty, its digit value is 0).
Every six-digit number is greater than any five-digit number.
yes
oo..this one is very hard.
With 123 digits you can make 123 one-digit numbers.
For now, I'll assume for simplicity that the numbers are positive. The number with the greatest amount of integer digits (before the decimal point, if any) is larger. If both numbers have the same number of integer digits, compare each digit in turn until you find one digit that is different. The number with the largest digit in this place is larger. Examples: 1234 is greater than 430, because it has more digits. 125 is greater than 117, because in the first digit they differ (second position from left), it has the greater digit. 0.007 is greater than 0.0009, because in the third digit to the right of the decimal point (the first digit where they differ), it has the greater digit (7 is greater than 0).
There are 5460 five digit numbers with a digit sum of 22.
Not necessarily. Consider 444. The digits are not different. The first and second digits are not multiples of 3 The first digit is not greater than the second digit. In spite of all that, 444 is a 3-digit number
There are 9 digits that can be the first digit (1-9); for each of these there is 1 digit that can be the second digit (6); for each of these there are 10 digits that can be the third digit (0-9); for each of these there are 10 digits that can be the fourth digit (0-9). → number of numbers is 9 × 1 × 10 × 10 = 900 such numbers.
