(int)(x+y)=(int)7.7=7

a % 3 *(int)(x+y)% 3/5 = 10% 3 * 7% 3/5 = 0

Note here: modular operation requires that all operands involved in the operation are integers, and the result is also integers. When all operands involved in division are integers, the result is also integers, and decimals are discarded, so the above operations are all plastic. Before /5, the answer is1; 1/5 because both sides are plastic surgery, the result is definitely plastic surgery, which is 0.

X+0 is float+int, and the final answer is of course 2.6.
