Hmm not sure about this question. It looks like part of the equation is 98/00 and anything divided by zero is undefined. Maybe the equation is wrong?
(89)56 +89 = 5073
56 + 89 = 145
89
145
0.6292
89 + (23 x 56/7) = 89 + (23 x 8) = 273
56: 2, 7 67: 67 75: 3, 5 81: 3 89: 89
56 + 33 = 89
145.
115
It's an example of a false statement.
