The left and right movement of the decimal point is essentially to reduce and enlarge the original number according to the multiple of 10
Moving one bit to the left means that the original number will be reduced by one time of 10, that is, 0.1
To move one bit to the right means to enlarge the original number by one time of 10, that is, 10
According to the meaning of the question, if the original number is x, move one digit to the right and three digits to the left, it is actually two digits to the left
It is to reduce the original number by twice 10, that is, 0.01
According to the equation, x-0.01x = 34.65, that is, X (1-0.01) = 34.65
The original number was 35
