Does AB mean the product of A and B or something else?
Hi all, I’m finding in a lot of job interviews I’m required to complete some basic aptitude tests so I’ve been checking out some examples online for practice and come across this example.
A=5
B=0
C=2
D=10
E=2
What is then AB + EE - (ED)B + (AC)E =
The answer is 103 but I’ve no idea how it was reached, getting to the 50+22 is easy enough but as soon as I hit the brackets I’m totally lost
I’m just looking for an explanation on how it was worked out and I apologize in advance if I’ve posted this in the wrong thread.

BTW here’s a screenshot of how it was expressed on the example.
I don’t know to be honest I’ve no more info to offer other than that screenshot I posted, I’m just reading those letters as straight out representations of their allotted numbers until I see a + or –
Does (ED)B mean 210x0 or 12x0 ? That’s assuming the those brackets indicate that the value within has to be multiplied with B which is 0
I’m 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 didn’t they give clear instructions to multiply the AB, EE and so on , after all they did give clear instructions to both + and –
So once again thanks very much emakarov & SammyS
