I was wondering how modulo works. I know how it works when the bigger number comes first, but not the opposite. I know that 7 % 3 = 1 as 3 goes up to 7 2 times and the remaining is 1. However, when it's 3 % 7. I have used the calculator it shows 3. Is this because 7 goes up to 3 zero times and the remaining is 3? Is that how it works?
Your reasoning is correct. Any time the divisor is larger than the dividend, the result of the modulo operation equals the dividend.
