For the second item Ifound the next solution:
8 / 7 + 6 X 5 – 4 = 31.71
Your solution to the first sequence is incorrect. It fails to follow the order of operations.
8/4+6-3*7 = 2+6-21=-13.
However, 8*4-6/3+7 = 37.
All of these solutions are incorrect.
5×5+5-5:5=25+5-1=29
not
5/5+5×5-5=1+25-5=21
8*4-6/3+7=37
