Hello it's Jesse your buddy. I also enjoy math it is great, and can help you find all kinds of things for example in science (Chemistry) since we can't actually see atoms because they are SO small we use math to find their size, and mass. I tend to get a bit off topic when I explain things because other interesting things pop up that I want to tell you about. I want to tell you about mass.Well, mass is a measurement of how much matter is in an object; weight is a measurement of how hard gravity is pulling on that object. Your mass is the same wherever you are, on Earth, on the moon, floating in space, because the amount of stuff you're made of doesn't change. But your weight depends on how much gravity is acting on you at the moment; you'd weigh less on the moon than on Earth, and in interstellar space you'd weigh almost nothing at all. This is thanks to math that we can calculate things that we can't see like atoms, or mass, or weight.
If you have any other questions about math or science or want me to explain, or something to you, because I remember you like science, i'd be more than happy to teach you about math and, or science
