Thinking of solving problems: In practical problems, division is generally used when the keyword is average, multiplication is generally used when multiple is used, addition and subtraction are generally used when the ratio is more or less, and formulas are applied according to keywords.

Problem solving process:

(284+826)÷5

= 1 1 10÷5

=222

A: The sum of 284 and 826 is 222 times that of 5.

Extended data [vertical calculation-calculation process]: align two addend numbers, and then add the numbers in the same counting unit respectively. When the addition result exceeds 10, 1 will be added to the high position, and the high position addition needs to accumulate the result of 1 to the low position.

Problem solving process:

Step 1: 4+6=0 to the high position, 1.

Step 2: 8+2+ 1= 1, move to the high position of 1.

Step 3: 2+8+ 1= 1 to the high position.

According to the above calculation steps, the combined calculation result is 1 1 10.
