9 -2 = 7
If there is a missing operator (as due to browser limitations mathematical operators tend to get stripped out of questions), then your question could be one of:
9 + (-2) = 9 - 2 = 7
9 × (-2) = -18
9 ÷ (-2) = -4½ = -4.5

(2/9) * (8/9) = (2*8) / (9*9) = 16/81 and: 2/9*8/9 = 16/81 2/(9*8)/9 = 1/324 2/(9*8/9) = 1/4 it depends on where you put the brackets
2^9 = 512 9^2 = 81
