What does the formula mean? Matters needing attention in mathematical formula
1, the meaning of mathematical formula refers to the formula listed in the calculation of numbers or algebras. In the primary school stage, the horizontal formula of the four operations is listed as vertical calculation, which means that a vertical formula is listed in the calculation process, which makes the calculation more convenient. And the sum of numbers is needed. Below the horizontal line, the sum should also be added horizontally.

2. The matters needing attention of mathematical formula are as follows:

Write the first addend on the top line first. If the two addends are different, write the number with more digits first.

Write the second addend on the next line. If the two addends are different, write the number with fewer digits.

Write "+"before the second number.

The "=" sign in the formula is indicated by a horizontal line and written below the second number.

The calculation results of two numbers are written below the horizontal line and aligned with the numbers above.
