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 =___________________________=_______________

找出由120到190最大及最小质数差
质数
最大质数 = 181
最小质数 = 127
所要求的相差 = 181 - 127 = 54
在1到10间的整数(不包括10自己)将复合数(非质数)的总和减去质数的总和,找出相差,
1到10间的复合数:4 6 8 9
1到10间的质数:2 3 5 7

相差 (4+6+8+9)-(2+3+5+7)=10
