★ Special symbols, such as root sign, open the right-click menu on the icon of the soft keyboard of the input method to select mathematical symbols or Greek letters, which contain many commonly used mathematical symbols. For your convenience, I put the commonly used special symbols at the top of the post title. Please look at the right side of the post title at the top of the math page. Copy it here if you can't find it in the input method? 0? 2 ? 0? 1 ? 0? 5 ? 0? 6 ? 6? 6 ? 6? 7 ? 6? 8 ? 6? 9 ? 6? 0 ? 6? 1 ? 6? 2 ? 0? 1 ? 6? 8 ? 6? 6 ? 6? 0 ? 6? 2 ? 6? 7 ? 6? 8 ? 6? 3 ? 6? 4 ? 0? 1 or

/f？ kz=4947394

★ Fraction one third1/3,7/x. "/"is used as the division symbol, so 3+4/2+2=3+2+2=7 instead of 3+4/2+2 = 7/2+2 = 3.5 or = 7/4,2/3x =

four

1+ -

x+ 1

★ superscript, power? 0? 2 ? 0? 1 ? 0? 5 ? 0? 6 ? 6? 6 is represented by 0, for example, 2 3 represents the cube of 2. The operation level of power is higher than that of multiplication and division, such as 2 3 * 9 = 8 * 9 = 72, 2 (3 * 2) = 2 6 = 64.

Copy the special symbol above and write it as 2? 0? Six is much better. As for other times, the font is too small and is not recommended.

Press ALT and then 186? 0? 2. the same ALT+ 185? 0? 1，ALT+ 178？ 0? 5、ALT+ 179？ 0? 6, but? 6? 6 can't be pressed out, do you want to use code in the post? express

★ Subscript? 6? 8 ? 6? 9 ? 6? 0 ? 6? 1 ? 6? 2...？ 6? 2

Use the above method Alt+832+ The number you want to dial can be represented by x2 or x2 without causing confusion, and brackets are recommended when representing the series a(n+ 1).

★ Root number √ code?

√3. If the radical sign is very long, put brackets √(3x+7).

Suggest beautiful typesetting

√3x+7

Multiple radicals and multiple radicals can be assisted by equal signs.

The root number of the third degree can be written as above, or it can be expressed as (x+ 1) (1/3).

★ Spaces and Baidu Forbidden Words

When n≥2 consecutive half-width spaces are put together, Baidu will replace it with 1 space, disfigure your post. Replace 2 half-width spaces with 1 full-width spaces before posting.
