If you don't know how to use times tables, they're not useful

Out of all the maths that people did at school,
why do they so often say that the times tables are the most useful?
I agree they can be useful.
If you know how to use them.
If you don't know how to use them
they're not useful.
I also find really useful:
addition, subtraction, angles, simple graphs, if a plus b = c and a plus b = d then c = d, and symmetry...
I've always liked symmetry.
