Answer:
First, let's divide 1563 by 47, so
So, first, we select 2 numbers from 1563 because 47 has two numbers. However, 15 is lower than 47, so we need to select one number more and get 156.
Now, we need to find a number that multiplied to 47 is 156 or closer to 156. This number is 3 because 47 x 3 = 141. We subtract 141 from 156 to get 15.
Then, we take another move down the 3, and we work with 153. So, again, we need to find a number that multiplied to 47 is 153 or closer. This number is again 3 because 47 x 3 = 141.
Subtract 141 from 153 to get 12. Since 12 is lower than 47 and there are no more numbers to move down, the division is ended.
Now, let's multiply 67 x 78
In this case, we first multiply 8 x 7 = 56, we type 6 and write the 5 in another place. Then, 8 x 6 = 48. But we have 5, so we type 48 + 5 = 53.
Then, we multiply 7 x 7 = 49, so we type 9 one place to the left and let the 4 in another place. Now, multiply 7 x 6 = 42, but we write 42 + 4 = 46.
Finally, we need to add the numbers. So, the result is 5226.
