= 5 * 5 + 604 + 2 + 957 + 3563 + 3 + 6534 - 7
= 25 + 604 + 2 + 957 + 3563 + 3 + 6534 - 7
= 25 + 604 + 2 + 957 + 3563 + 3 + 6534 - 7
= 6511 + 2 + 957 + 3563 + 3 + 6534 - 7
= 6513 + 957 + 3563 + 3 + 6534 - 7
= 7470 + 3563 + 3 + 6534 - 7
= 11033 + 3 + 6534 - 7
= 11036 + 6534 - 7
= 17563 - 7
= 17556

Therefore, 5*5+604+2+957+3563+3+6534-7 equals 17556.
