For example:
The vertical division of 84 divided by 6 is as follows:
Take 75 divided by 5 columns as an example. First, the highest dividend, that is, the tenth 7, is divided by 5, and the quotient is 1. The remainder is 2, and then the quotient is 5, so the final result of the vertical form is 15.
In mathematics, suàn shììì refers to the formulas listed when calculating numbers (or algebraic expressions), including numbers (or letters instead of numbers) and operation symbols (four operations, powers, roots, factorials, permutations and combinations, etc. ). According to the different calculation methods, the formulas are generally divided into horizontal and vertical. Different from expressions, expressions are meaningful expressions that connect data of the same type (such as constants, variables, functions, etc.). ) Use operation symbols according to certain rules.
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.
Summary 1: When dividing vertically, start with the highest dividend.
2. If it can't be divided, then use the highest bit and the next bit to synthesize a number to divide until it can be divided by the divisor.
3. When calculating the division vertically, start the division from the highest bit, and align the digits in the process of column verticality.
