Math History
Far more interesting than one might first expect, the history of mathematics is filled with bitter rivalries, political machinations, and incredible innovations by some of the most amazing minds in history. Post all questions concerning individual mathematicians, the development of mathematical theories, and the sociological impact that resulted into this category.

Im bored with your real-life is this bad?
Answer How can you be bored with my real life? I think that your question should be I'm bored with my own real life, is this bad? One might think that it's bad and others may say, not really depending on who you talk to. Sometimes life has it's up's and down's and sometimes we get fed up with so many downs. There is no easy solution to this problem with the possible explanation that whatever it is that is making you feel down all the time, needs to be explored, discussed with a proffessional and dropped out of your life so that you feel better about you and perhaps the people around you.
It is: (151*12)+1 = 1,813 inches in height
The mode is the value that occurs most often. So just find what number appears the most and you have your mode. A good way to remember this is to think, mode = most.
18,24,24,26,30,30,30,38,44?
So in this case the mode is (30)
look at the figures the most comn figures will be the mode
e.g 10,13,14,8/10,10
the mode is 10
How do you convert 1m3 of concrete to kilogram?
To do this you would need to know the density of unmixed concrete (i.e what is the weight of concrete per unit of volume), and the ratio of concrete to water required. (I assume you mean 1m^3 of mixed concrete (with water) to kg, rather than the unmixed concrete powder). With these bits of information the conversion is relatively simple, however I don't know where to find this information from. Alternatively, just the density of mixed concrete would suffice.
