Arithmetic and assignment
Slide 1 / 5Arithmetic: + - * / % (remainder) ** (power), plus ++ and -- to add or subtract 1.
10 % 3 → 1 2 ** 3 → 8
Assignment shortcuts update a variable in place:
score += 10 // score = score + 10 price *= 1.2 count++
Precedence follows maths: * and / before + and -. Use parentheses to be clear: (a + b) * c.
