找出由120到190最大及最小質(zhì)數(shù)差
質(zhì)數(shù)
最大質(zhì)數(shù) ＝ 181
最小質(zhì)數(shù) ＝ 127
所要求的相差 ＝ 181 － 127 ＝ 54
在1到10間的整數(shù)（不包括10自己）將復(fù)合數(shù)（非質(zhì)數(shù)）的總和減去質(zhì)數(shù)的總和,找出相差,
1到10間的復(fù)合數(shù)：4 6 8 9
1到10間的質(zhì)數(shù)：2 3 5 7
∴
相差 （4＋6＋8＋9）－（2＋3＋5＋7）＝10
find the difference between the largest prime number and smallest prime number from 120 to 190.
find the difference between the largest prime number and smallest prime number from 120 to 190.
larget prime number =
smallest prime number =
the requied difference =__________-__________=___________.
for integers that lie between 1 to 10 (excluding 10 itself),subtract the sum of all the prime numbers from the sum of all the composite numbers,find the difference.
composite numbers between 1 and 10:____________________________
prime numbers between 1 and 10:_______________________________
∴
thw difference =___________________________=_______________
