-对于每个整数n> 1，函数族fn，a，b由fn，a，b（x）≡ax+ b mod n定义为a，b，x整数和0
+For every integer n>1, the family of functions fn,a,b is defined
 
-对于1≤n≤N，F（N）=ΣR（n4 + 4）。 F（1024）= 77532377300600。
+by fn,a,b(x)≡ax+b mod n for a,b,x integer and 0
 
-求F（107）（mod 1 000 000 007）
+F(N)=∑R(n4+4) for 1≤n≤N. F(1024)=77532377300600.
+
+Find F(107) (mod 1 000 000 007)
