1--what is the result?
2--what are the units of measurement?
3--how can we interpret this units of measurement for the sum of 1m+1s in English with just words? For the derivative we say: "the derivative is the rate of change". What is the addition of units of measurement? The problem is that mathematics in general has no units of measurement and in order for me to gain deeper understanding of it I need units. You know?
