The factor pairs of 21 are:1, 213, 7Therefore, the number 21 has two pairs of positive integer factors.
To find the pairs of whole numbers that sum to 110, we can express one number as ( x ) and the other as ( 110 - x ). The pairs are formed by choosing different whole number values for ( x ) from 0 to 110. This results in a total of 111 pairs, including (0, 110) and (110, 0), as well as all combinations in between. Thus, there are 111 pairs of whole numbers that sum to 110.
There are infinitely many pairs of numbers including many pairs of positive integers. An easy pair to remember is 1 and 675.
3 pairs of whole numbers add up to 7: 1 +6, 2+5, 3+4 (0+7 also equals 7, but zero is not a whole number)

The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
it is a whole number, it has two digits, it is not a prime number, it is positive, 4 months have this many days
