Well maybe u can try searching for the calculator online by specifying your phone model... Or u can always try other calculators in Google play

You will have to re-flash your Intex Aqua with its stock ROM to get that original calculator app back (and since it will be running its original firmware again you'll need to re-root). You might find it easier to just look through the Play Store at the calculator apps again and just find one that does fit your needs.
