Function to repeat number N times I am not a math person, but is it possible to repeat one number N times without programming langs or programs? If yes, which type of function can I use to do it? For example: number 2 repeat 3 times and get 222?

You could multiply it by $111 = \dfrac{10^{3} - 1}{10-1}$
Adjust the $3$ if you want a different number of repeats and the $10$s if your original number has more digits.
