What is the off-design calculation of decimals in the second volume of the fourth grade? Off-balance-sheet calculation, that is, recursive calculation, is an operation that completely writes out the calculation process, that is, off-balance-sheet vertical calculation. When calculating mixed operations, it is usually to work out an expression step by step (step by step, you can't write an equal sign on the original formula), and the process of each step should be written out. Generally speaking, the equal sign should go forward and not be aligned with the first line. That is, to leave the original calculation.
For example:
25+65+98
=90+98
= 188
How to calculate the distortion?
How to calculate the distortion? The main thing to master is to remember to calculate multiplication and division first, and then add and subtract. In the successive calculation of multiplication and division, it should be calculated from left to right. When you encounter parentheses, you must first calculate the inside of parentheses. In the process of separation, the operation sequence line should be drawn according to the operation sequence, and the "three checks" should be done well. First of all, check whether the numbers and symbols copied from books to exercise books are correct. Second, check whether the numbers and symbols copied from horizontal to vertical are copied correctly. Third, it is necessary to check whether the draft is copied vertically, horizontally, and whether the decimal point position is correct or not.
