最全面最标准的数学符号、公式的英语读法大全

【国际课程】最全面最标准的数学符号、公式的英语读法大全
"+"当作运算符加号时读作plus，比如：
1+2 ➡️ one plus two
当"+"放在数字前表示正数时，读作positive，比如：
+4 ➡️ positive four
同样，“-”也有minus和negative两种读法，分别是减号和负数。
"×"两种读法都可以，国外的教授会常常读成times，可能因为比较简单吧，比如：
9x6 ➡️ nine times six
“÷”只有一种读法divided by，就是被…分成几份
1y three
注意：
其中plus和minus是不用第三人称单数形式的，因为plus和minus根本就不是动词，而是介词。
但是乘和除，的的确确是动词，出现第三人称单数的形式。
