7-%28-13%29-%28-4%29%2B%28-9%29%2B2.....recall, subtracting a negative number is the same as adding a positive; so, 7-%28-13%29=7%2B13

7%2B13-%28-4%29%2B%28-9%29%2B2....minus%2Aminus=plus; so,-%28-4%29 is actually -1%2A%28-4%29 and it is 1%2A4=4

7%2B13%2B4%2B%28-9%29%2B2....minus%2Aplus=minus; so,%2B%28-9%29 is actually %2B1%2A%28-9%29 and it is -9

7%2B13%2B4-9%2B2

26-9
