Horizontal formula is a calculation formula written in a horizontal row, which is usually calculated by symbols such as plus sign, minus sign, multiplication sign and division sign. For example, 3+7= 10 is horizontal. Its characteristic is that the calculation process is simple and clear, easy to understand and can save space. In horizontal style, priority is usually calculated from left to right.
A vertical type is an expression represented by a vertical column. Usually used in advanced mathematics or complex calculation problems. In vertical form, all numbers are arranged in vertical columns, and then bitwise addition, subtraction, multiplication or division are performed. For example, 4x 12=48 is the vertical type. The characteristic of vertical type is that each column is a number, which is very convenient to use in the calculation of complex multi-digit numbers that are difficult to write in horizontal type.
Advantages and disadvantages of horizontal and vertical.
Horizontal and vertical have their own advantages and disadvantages. For the horizontal style, its advantage is concise and clear, at a glance. And it is convenient to calculate the power of a certain number, what is the last digit and so on. , suitable for oral arithmetic or elementary school mathematics foundation. The disadvantage is that it is impossible to calculate the multiplication and division of multiple digits, and the calculation process is long and easy to make mistakes.
For vertical, the advantage is that it is suitable for multi-digit calculation and can ensure the calculation accuracy. The disadvantage is that the calculation process is complicated and not suitable for oral calculation. In addition, sometimes it is necessary to calculate vertical borrowing and carry, which is easy to make mistakes.
