Answer 2

Examples:
1) Multiplying (for 10 , 100, 1000 always moving to the right)
12.45*10=124.5*10 Moving to the right (1 "step")
37.321*100=3732.1 Moving to the right (2 "steps")
1.56789*1000=15678.9 Moving to the right (3 "steps")
2) Dividing (for 10 , 100, 1000 always moving to the left)
56.89/10= 5.689 Moving to the left (1 "step")
234.98/100=2.3498 Moving to the left (2 "steps")
78956.67/1000=78.95667 Moving to the left (3 "steps")
