Question

Take any product from the 7 times table, say 63.
Multiply the ones digit by 5 (3 × 5) = 15
Add the tens digit to the product (15 + 6) = 21
Multiply the ones digit from the sum by 5.
(1 from 21 in this example) (1 × 5) = 5
Add the tens digit (5 + 2) = 7
Try the same with other products of 7. What do you notice?
