= 3+3+4

= 6+4

= 10

Question 2: What do you mean by extra-formal calculation? Math? Tons, kilograms and grams in the second grade of primary school

Question 3: What is off-balance-sheet calculation in grade two? Unbalanced calculation, that is, recursive calculation, is an operation that completely writes out the calculation process, that is, the calculation that deviates from the vertical.

When calculating mixed operations, an expression is usually calculated step by step (step by step), 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, leave the original calculation, such as:

25+65+98

=90+98

= 188

Question 5: What is the significance of mathematical parting calculation? The departure calculation of grade two is recursive calculation, which is an operation to write out the calculation process completely, that is, the calculation out of horizontal form.

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.

Question 6: Off-balance-sheet calculation process of senior two.

9×9+ 100 =8 1+ 100= 18 1

5×9+ 16 =45+ 16=6 1

64÷8+ 104 =8+ 104= 1 12

54÷6+65 =9+65=74

36÷4+99 =9+99= 108
