If you were at 54 on the number line you would have to cross zero and go an extra 13 steps to get to -13.
So we want the difference between 54 and -13 or 54- -13 which becomes 54+13 which is 67 - that is the range
7,000+500+2
2(3751)
7x10^3+5x10^2+2X10^0
5(1500.4)

8(8x64^2-1) factorises the lhs.
how it's equal to zero is beyond me
