What does this mean? 100=

x is the absolute value function. It measures how far from zero x is, whether positive or negative.
x = x if x >= 0
That is, if x is not negative, x is just haw far away x is.
x = x if x<0
So, if x is a negative value, x is still positive
Similarly, x10 is how far away from 10 x is.
So, 100 = 100
3 = 3
