# How to iterate over an “Input” function?

I wasn't sure what to name this title, I will explain this code just incase some people actually aren't running it on Mathematica..This code will ask you "what is #1 * #2", where #1 and #2 are random integers between 1 and 12 as defined by a and b.. If you get the answer right it says "Great Job" but if you get it wrong it will say "Try again"..

I guess I have 2 questions:

How can I have this repeat multiple times (well use 3 iterations), so the input window would pop ups and ask 3 different multiplication problems...

Assuming we get it wrong, how can I have the same input window ask the same question again until it is answered right?

 Clear[answer,a,b,list];

a = RandomInteger[{1, 12}];
b = RandomInteger[{1, 12}];
list = Input["what is " <> ToString[a] <> " times " <> ToString[b] <> "."];
If[list == a*b, Print["Great Job"], Print["Try Again"]]
list


Let me know if I need to clarify anything

Do[SeedRandom[];
a = RandomInteger[{1, 12}];
b = RandomInteger[{1, 12}];
list = Input[
"what is " <> ToString[a] <> " times " <> ToString[b] <> "?"];
If[list == a*b, Print["Great Job"],
While[list != a b,
list = Input[
"Try again; what is " <> ToString[a] <> " times " <>
ToString[b] <> "?"]
]
]
