Problem Solving

Manu collected 183 stamps in January. By March he had 834. How many stamps did he add to his collected in February?

834 - 183 =
800 - 180 =620
34 - 3 =31
620 + 31=651

So what i know is that i can not take away 30 from 80 so what i do is combined 80 and 100 which is =180 So 180 - 800=620 then i am left with 34 and 3 then i do 34 - 3=31 then i add them all up together so 620 + 31=651
