Work out the value of 2b 6 when b=9

There is no sign in between 2b and 6.

Case 1:

Assuming the sign is '+'

Then, 2b + 6 for b = 9 is given by 2 (9) + 6 = 18 + 6 = 24.

Case 2:

Assuming the sign is '-'

Then, 2b - 6 for b = 9 is given by 2 (9) - 6 = 18 - 6 = 12.

Case 3:

Assuming the sign is 'x'

Then, 2b x 6 for b = 9 is given by 2 (9) x 6 = 18 x 6 = 108.

Case 4:

Assuming the sign is ':'

Then, 2b : 6 for b = 9 is given by 2 (9) : 6 = 18 : 6 = 3.
