When you calculate 1 modulo 7, you are essentially finding the remainder when 1 is divided by 7. Since 7 is larger than 1, 1 cannot be divided by 7 without going into fractions. Therefore, the remainder is simply 1.
Mathematically, this can be represented as:
1 % 7 = 1
This means that 1 modulo 7 equals 1.
