I didn't got the remainder thing

Question

7% (5//2)

Answer 1

By following the PEMDAS rule alternative to BODMAS in maths, Parenthesis comes first.

Double // produces exact integer not float and not to the nearest whole number( as in rounding a number) eg. 5//2 = 2 not 2.5 or 3

Also the remainder of modulo % division is it's answer, hence

7 % (5 // 2) = 7 % 2 ( parenthesis 1st and applying double // rule above )

Also, 7 divided by 2 = 3 remainder 1

and by applying modulo rule the remainder is the answer, hence 7 % 2 = 1

Therefore:

7 % (5 // 2) = 7 % 2
= 1

Answer 2

that was very clear thanks
