Two methods of printing mathematical symbols are given, which can be learned.
How to type mathematical symbols:
Method 1:
1, because in the input method
In this way, mathematical symbols can be obtained directly.
Method 2:
1. When you want to input content, press and hold the Shift+Ctrl key to bring up the sogou input method.
2, through the sogou input method, right-click to select the soft keyboard, and then you can select mathematical symbols, which can be found.
3. Click on the mathematical symbol to be entered, and the symbol will be typed.
Extended data:
Symbols commonly used in mathematics:
1, sign of quantity: for example, I, natural logarithm base e, pi.
2. Operation symbols: such as plus sign+,minus sign-,multiplication sign ×, division sign ÷, union of two sets ∨, intersection ∩, logarithmic log, differential d, integral ∫, etc.
3. Relative symbols: for example, "=" is equal sign, ""or ""is approximate sign, "≦" is unequal sign, ">" is greater than sign, "
4. Combination symbols: such as parentheses (), square brackets [], braces {} and enclosed lines.
5. Natural symbols: such as positive sign "+",negative sign "-"and absolute value sign "∨".
6. Omitted symbols: sine sin, limit lim, because ∵, so ∴, sum ∑, multiply ∏, take out all different combinations of R elements from N elements at once, factorial! Equal sign.
