Anyway they could also have shown a neuron firing to into synapse, ie how did you work it out > I thought about it (duh)
or drawn a picture of a calculator.
I had to think a little bit to work it out in my head, I normally work out how much it costs for said amount of items and then subtract that away from the total amount of monies
so other way around of what you did above
2 * £0.35 = £0.70
£2.00  £0.70 = £1.30

Under BODMAS that is the same as "total  qty*price" or in this case "2.00  2*0.35"
not sure why someabc put brackets around it... That would of been incorrect, if the teacher was feeling mean :P

what's bodmas stand for again and brackets would of been correct as the b in bodmas stands for brackets which means to do that part of the calculation first then do the rest of it although it should of been
2(0.35*2)
