This is due to operator precedence, Gauhar Rahman Niazi . First, the echo line checks the division of $str2 and $str3 (20 divided by 5 = 4). Only then it sums this result with $str1 (10+4). Hope it helps, even if so long afterwards.

Also the string "15" is implicitly converted to integer when doing calculations.
