You are missing the ")" so I can only guess where it should be:
7 + 8(3 by the power of 2) - 2 =7 + 8(3²) - 2 =
7 + 8 x 3² - 2 =
7 + 8 x 9 - 2 =
7 + 72 -2 =
77 -2 =
75
83 + 6*7*9 + 1 = 512 + 378 + 1 = 891
83
7 + 33 + 16 + 22 = 78
5 + 1 + 4 + 22 + 7 = 39
7 + 7 + 8 = 22
-29
169
7/83 = 73/83 or 343/512.
7*6 + 22 - 32 = 42 + 4 - 9 = 37
It depends on the order of operations. 88, minus 22, plus 7, is 73. 88 minus (22 plus 7) is 88 minus 29, which is 59.
22 plus 3 times 7 is equal to 43.
It is 9/8 plus 7/3 = 83/24
