Suppose I have the following code:
ti = var('ti', latex_name = 't_i')
yi = var('yi', latex_name = 'y_i')
expr1 = yi -ti
expr1 will display as $$-{t_i} + {y_i}$$
Is there a way I can rewrite expr1 so that it will display as:
$$ {y_i} -{t_i}$$
?
I've tried using hold=True like so:
expr1 = yi.add(-ti, hold = True)
but that did not work.
