We subtract the largest multiple of 26 which is less than 290. The answer we get after the subtraction is the answer.
Largest multiple of 26 is 286, because 26 * 11 = 286
290 - 286 = 4.
290 mod 26 = 4.
b). 9^(-1) mod 26 = 0.111 mod 26.
0 * 26 = 0.
The largest multiple of 26 which is less than 0.111 is 0.
We subtract this from 0.111
0.111 - 0 = 0.111
9^(-1) mod 26 = 9^(-1) = 0.111
c). -15 mod 26.
Take note this is negative numbers. But same rules applies here.
The largest multiple of 26 which is less than -15 is -26.
We subtract this from -15
-15 - (-26) = -15 + 26 = 11
-15 mod 26 = 11
