Upper Case Ascii starts with 65 to 90 Lower Case Ascii Starts with 97 to 122 use the parenthesis to get the correct outcome Encrypt Upper Case String with Ascii Code C = (M + K) mod 26 + 65 Decrypt Upper Case String with Ascii Code M = (C - K) + 26) mod 26 + 65 Encrypt Lower Case String with Ascii Code step 1 C = ((M + K) mod 97) step 2 C = mod 26 + 97 Decrypt Lower Case String with Ascii Code M = (C - K) + 26) mod 97

u the best

Time (14:50) the m2+k2 its 0+8=8 and it's the only one that you do not follow the equation 8-26=12 but for some reason you don't do that and it is staying as 8. Please tell me why it is staying like this. I don't get it
