#3. [(2+3)^3-4(5)]+7
My way of solving:
[(5)^3-4(5)]+7 <b>You are ok to here.</b>
[123-4(5)]+7 <b>5*3 125 not 123.</b>
[123-20]+7
[103]+7 <b> a second mistake here. 103 + 7 = 110</b>
My answer: 109 <b> the correct answer is 112.</b>

#4. [25/ (2^3-3)]*2
My way of solving:
[25/(8-3)]*2
[25/5]*2
[5]*2 <b>You are ok to here. 5^2 = 25 and not 10.</b>
My answer:10
