what is 9 x 9 - 9.......?

9 x 9 - 9
= 81 - 9
= 72

9 x 9 - 9 =
81 - 9 =
72.

If there are no signs in the parentheses, the multiplication must be done first !!

9 x 9 - 9 = 72

72

72

if it's (9*9) - 9 answer is 81 - 9 = 72
if it's 9 * (9-9) answer is 9 * 0 = 0

9*9=81
81-9=72

81 - 9
= 72
... seriously?

its like 9 x 8 which is 72

81 - 9 = 72
