4.02, first you add together 2.1 and 3.32, then once you get that answer (5.43); you subtract 1.4. Remember that when adding and subtracting to always go left to right.
Hi there! :) The answer to your question is 4.02. I did 2.1+3.32= 5.42 then I did 5.42-1.4= 4.02. That I how I got the answer.
Hope I helped! ;D
