That, my friend would be 98 (if i read your question correctly)
since 4 is 2 times 2 just double 7 twice: 7 doubled = 14 and then 14 double = 28
It means you double 7. So 7 * 2 = 14
The word pertaining to "seven times as much", such that double means "twice as much" is septuple.
It is 14! You double the seven! Like 7 + 7= 14 is the same as 2x7= 14!! How come you asked this question?
4+4+4+4+4

4 x 7= 28 28 x 19 = 532 A Easy way to do this is to times 28 by 10. Then double it to make 560. Then subtract 28 to make 28 x 19 = 532
1 times 7 is 7 ....... 2 times 7 is 14 ....... ....... 3 times 7 is 21 ....... ....... ....... 4 times 7 is 28 ....... ....... ....... ....... 5 times 7 is 35 ....... ....... ....... ....... ....... 6 times 7 is 42 ....... ....... ....... ....... ....... ....... 7 times 7 is 49 ....... ....... ....... ....... ....... ....... ....... 8 times 7 is 56 ....... ....... ....... ....... ....... ....... ....... ....... 9 times 7 is 63 ....... ....... ....... ....... ....... ....... ....... ....... ....... 10 times 7 is 70 ....... ....... ....... ....... ....... ....... ....... ....... ....... ....... 11 times 7 is 77 ....... ....... ....... ....... ....... ....... ....... ....... ....... ....... ....... 12 times 7 is 84 ....... ....... ....... ....... ....... ....... ....... ....... ....... ....... ....... .......
7 to the power of 5 is 16,807.
7 times 7 times 2 is equal to 98.
7 x 7 x 7 x 7 = 2401
if you want to double something straight away you can add the numbers 2 times and it would be easyer if you add them in coulems. This is an exsample : double 397you first double the numbers by adding them together (the numbers both have to be the same)397 + 7+7= 14 put a 7 in the coulem. put a 1 in the 9 coulem3971 1_____ 9+9= 18 pun an 8 in the coulem and a 1 in the hundrets coulemadd them up (theas ones are easy)
