Hi! I need help with some math questions. Not problems though, I’ll show what I mean. It says, “Why do you think it is important to include negative numbers in our number system?”, and, “What is special about zero (0)?”

Would appreciate it if you helped!

Negative numbers are most important especially in the field of physics and chemistry. They help us in real life geometry and in almost everything. The discovery of the number system has changed the human civilization to such a great extent, that, without it, we can't even think of architectures and the nature's law(by calculus).

Dominantly, zero is the most ever used number and is very important to express anything.

Without it, you couldn't have the digital world (simply, no computers, no phones, no machines and no A.I.).

As we all know, Dr. Aryabhatta, the legendary guy, who made the no. '0', holds the credits!

I hope it will be useful.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
