The value 
So, 
Thus the exact value of 
21 divided by 3 is 7 then multiplying 7 to 6 which is 42 and after you're multiplying 42 to 10 which is 420.
It would be written like this, X+7< 53, because the sum of that number cannot be more than 53, you would put a less than sign to represent that, and in case the sum can be 53 as well then it would be: X+7

53
