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.
