Matt

6 – 4(3 – 5)2 + 30 ÷ 5
6 – 4(–2)2 + 30 ÷ 5
6 – 4(4) + 30 ÷ 5
6 – 16 + 30 ÷ 5
−10 + 30 ÷ 5
20 ÷ 5
4
Karen

6 – 4(3 – 5)2 + 30 ÷ 5
6 – 4(–2)2 + 30 ÷ 5
6 – 4(−4) + 30 ÷ 5
6 + 16 + 30 ÷ 5
6 + 16 + 6
22 + 6

Karen was wrong because the problem was supposed to be 6-4(4)+30/5 like matt did 6-(6)+30/5 , -10+30/5 , 10+6 matt was also incorrect because he added -10+30 before dividing 30/5 the answer is -4.
