Add 11 once and remove 7 thrice
80+11 = 91
7X3 = 21
91-21 =70

Yes, because 80 + 11 - 7 = 84 is a multiple of 7.

You have to fill numbers in place of question marks. The numbers that you can use are 1, 3, 5, 7, 9, 11, 13 and 15. You can repeat the numbers if you like.

Start with a three-digit number and repeat the digits to make a six-digit number, for instance 379379. Now divide by 7, then divide the answer by 11 and then divide this answer by 13.
