Does AB mean the product of A and B or something else?
Hi all, Iím finding in a lot of job interviews Iím required to complete some basic aptitude tests so Iíve been checking out some examples online for practice and come across this example.
What is then AB + EE - (ED)B + (AC)E =
The answer is 103 but Iíve no idea how it was reached, getting to the 50+22 is easy enough but as soon as I hit the brackets Iím totally lost
Iím just looking for an explanation on how it was worked out and I apologize in advance if Iíve posted this in the wrong thread.

BTW hereís a screenshot of how it was expressed on the example.
I donít know to be honest Iíve no more info to offer other than that screenshot I posted, Iím just reading those letters as straight out representations of their allotted numbers until I see a + or Ė
Does (ED)B mean 210x0 or 12x0 ? Thatís assuming the those brackets indicate that the value within has to be multiplied with B which is 0
Iím totally and utterly confused
I've worked it out
5x0 = 0 + 2x2 = 4 - (20)^0 1 = 3
(10)^2 = 100
3 + 100 = 103
103 = Correctamundo
This is just a personal bugbear, but why didnít they give clear instructions to multiply the AB, EE and so on , after all they did give clear instructions to both + and Ė
So once again thanks very much emakarov & SammyS
