Multiplication symbols are generally divided into "*" and "×" on the computer, which can be considered as multiplication, but the gameplay is different. "*" is in the number 8 in the upper row. You can switch the input method to English, and then press the "shift" key on the keyboard+the number 8 in the upper line. "X" requires an input method. You can enter it by pressing "Cheng" on the keyboard in turn.

163 1 year, the British mathematician William Oughtred multiplied two numbers by x for the first time in his book "The Key to Mathematics", which is a modern multiplication symbol, and later it became more and more popular. In a letter written by Leibniz to johann bernoulli on July 29th, 1698, Leibniz proposed to use a point to represent multiplication, so as to avoid confusion between the X symbol and the letter X ... which shows that multiplication is quite popular. Now European continental schools (Germany, France and other countries) stipulate multiplication. Other countries use × as the multiplication sign and decimal point. Our country stipulates that × or can be used as a multiplication sign, and the multiplication sign before letters or brackets can be omitted. Because this symbol is inconvenient to input, it is generally replaced by the English letter X in daily communication. On HTML and XHTML, you can enter an entity reference of ×, × or ×. In an arithmetic book published by Stiefel in 1545, capital letters M and D stand for multiplication and division respectively. Steven also adopted this symbol in the book published by 1634. David (159 1) regards AinB as the product of a and b, and some manuscripts and printed materials of15th century still use juxtaposition multiplication, such as 6x and 5x2. But there must be letters, because 5 means 5+ instead of 5x, and this notation is still in use. In the west, X is called St Andrews Cross, which has nothing to do with mathematics. /kloc-This symbol was used in some mathematics books published in the 6th century, but it was not used at the beginning of modern times. It represents two independent multiplication operations, such as 315172x174715 and 395903x295448, which represent modern mathematics. Diophantine diagrams in ancient China and ancient Greece did not use multiplication sign, while the latter used two numbers to represent multiplication (the same as addition). In the remnants of Bahshali in India, numbers are arranged in character codes.
