To calculate whether a number is a multiple of 7, double the last digit and subtract it away from the rest of the number. If this following number divides by 7 without a remainder, then the number is divisible by 7. Continue the process if necessary.
In this instance, 100 - (1 x 2) = 98/7 = 14. 1 - (4 x 2) = -7/7 = -1
Therefore, 1001 is a multiple of 7.
