This code works because it creates two points with a known best fit line: the best fit line through (0,0) and (1,N) is y=Nx+0. [[TI-BASIC:LinReg(ax+b)|LinReg(ax+b)]] calculates this best fit line, and stores its equation to Y₁.

Then, we use [[TI-BASIC:Equ►String(|Equ►String(]] to store this equation to Str1, which now contains "NX+0" with N replaced by the numerical value of N. After that, the [[TI-BASIC:Sub|Sub(]] command get rids of the "X+0" at the end, leaving only the string representation of N.

This routine uses L₁, L₂, and Y₁, so you should [[TI-BASIC:Cleanup|clean up]] those variables at the end of your program. If you're working with the graph screen in [[TI-BASIC:Graphing_Mode#function|function]] mode, storing to Y₁ can be a problem since it will draw an unwanted line through your graphics. Use r₁ instead but make sure the calculator isn't in [[TI-BASIC:Graphing_Mode#polar|polar]] mode.

'''Note:''' This only works for real numbers. With complex numbers, such as imaginary numbers, you can use this code at the end of the first to get the same effect with ''i'' in it.
