Hi does this mean I make a= 1 and b=3 ? then I do the formula, 3 + 1*3 and that times two?

Uh, so you mean taking 2 Operators times X? I dont really get it
Hi! I solved it, thx for your help! Now I get what they´re saying, at first I did NOT interpret the question right so to speak.. I took 2 Op (3 + 1*3), that gave me -> 3 + 2(3 + 3) = 15
