The Number Zero Hidden in the Line
Foul play!
What's wrong with this?
You should've aligned the digit places correctly!
But why is there a blank after 74?
One blank
What is hidden secretly here is the number 0.
In the second line,
you shouldn't calculate 37X2
but calculate 37X20!
An invisible number that represents an empty space
Then why is 0 needed?
37 (thirty-seven) 307 (three hundred and seven)
370 (three hundred and seventy) 3007 (three thousand and seven)
If all the number zeros disappear,
we can't figure out the distance between 3 and 7.
And we can't read the numbers exactly either!
When you multiply by more than two digit numbers,
remember the number zero hidden inside the line!
The number that is less than 1 but is placed after 9
0
0 represents nothing, but it is an essential number.
