Vertical type means that each transition number is changed by the last transition number, and then the single digits of the last transition number are multiplied by 2. If carry is needed, proceed to 1, then increase the unit number by ten digits, and so on, and add a new operand to the unit number.
Extended data:
The method of vertical calculation:
add
The same numbers are aligned. If the sum exceeds 10, it will move forward to 1. (The numbers should be aligned. ) such as:
435
+697
———
1 132
subtraction
If the same number is aligned, borrow 1 from the previous number as 10 if it is not reduced enough. For example:
756
-569
————
187
increase
The i-th bit of one number is multiplied by the j-th bit of another number.
It should be added to i+j- 1 bit of the product.
separate
For example, 42 divided by 7.
On a scale of 4 [from high to low]. When calculating the division vertically, start from most significant bit, such as: 42 from most significant bit 4; If it is not divisible, such as: 4 is not divisible by 7, then use the highest bit and the next bit to synthesize a number to be divisible until it can be divisible by the divisor; For example, 4 in 42 is not divisible by 7, and 4 and 2 can be combined into a number. 42 divided by 7, the quotient is 6.
Find the arithmetic square root
1, because each complement needs two digits, so when the number of roots is more than one, make sure that the complement can't clip decimal points. For example, three digits must be operated separately from hundreds, and ten digits and one digit are added when complement is added.
