some operators go first disregaring order in which they are seen on the screen.
for example:
1 + 2 * 3 == 7
because * has precedence over + so * is done first
2*3 = 6
1+6 = 7
0
+ sign: Plus (5 + 6 = 11)
- sign: Minus (5 - 6 = -1)
* sign: Multiply (5 * 6 = 30)
/ sign: Divide (6 / 4 = 1.5)
% sign: Remaining (4 % 6 = 2, 2 % 10= 0)
// sign: Divide without decimal (5 // 2 = 2, 10 // 8 = 1)
Note that it doesn't round the number up, it simply removes it, so even a result of a division that is 1.9, it'll turn to 1.
