Its been long enough. Thanks for the keyring Vista.
3 pistons = 30 hence a piston equals 10
a piston plus a tyre plus a tyre = 20 a piston already = 10 so tyres must equal 5
a tyre plus a pair of shock absorber plus a pair of shock absorber = 9 thus a pair of shock absorbers must = 2
Our final equation poses a tyre + a single shock absorber X a piston or 5+1x10.
Mathematics does not have a primary left to right protocol but an order of operations or rules. Some know it as BODMAS, others BIDMAS or PEDMAS.
SO when presented with an equation solve the Bracketed then Orders, Divisions, Mutiplications, then Additions and finally Subtractions. so following the RULE our equation would look like this when reordered to read left to right. 1x10+5 or 5+(1x10) or as presented 5+1x10 which equals 15
